  1. understand, uboot and kernel have different dtb, that is why h96max+ starts, with uboot as seen by serial cable, but then when hands over to kernel dtb does not power uSD slot, something non-standard with regulators. So, it can't find its root filesystem, because slot is dead, no power You see no hdmi display until quite late in the boot, so it seems dead, just can't read uSD slot It there is a usb stick ALSO plugged in, will find root fs on usb stick.. uSD slot continues dead, unpowered easyb and hexdump have made dtb for h96max+/T9 that make regulators work. I don't know about other models
  2. I hope you don't expect me to do it for you? I am going to assume that you have broken that image up into the partition images I don't know if you are using win or linux, no matter There are hexeditors for both, a gui vesion is my recommendation, wxHex or okteta or ghex, I tend to use okteta load kernel.img into hexeditor, control f , make sure the hex button is selected, enter the signature above. It will be a good sign if it is found at the begining of the line, make a note of the address, keep searching. Then, in calculator, set decimal , address/1024, should be even, no remainder If so,, try dd if=kernel.img of=test bs=1024 skip=(above number) count=70 (Input file, output file, block size) Check test, load into hexeditor, should begin with signature, if not, you screwed up Then try to decompile, as usual If you don't find it appended to kernel, search in other images
  3. Are you saying that there is no resource.img? You do know that the dtb is 2K into resource.img (IIRR)? use dd to strip Sometimes the dtb is appended to the kernel,,, anyway search, with a hexeditor for D0 0D FE ED 00, at an even K boundry d00dfeed00 it the "signature" for dtb's. Most dtbs are about 60-65K in size Most of the resource.img is an (graphic) image file (or 2) for the splash screen I haven't found android dtbs to be very useful And, BTW how well does easyb's dtb work for you,, does everything work, both usb, ethernet? I have 46d uptime, I seldom reboot
  4. Digit: with a working and non-working situation,, compare lsusb ,,, lsusb | wc -l ,,, dmesg | tail -15 (just after dongle inserted,, ie unplug, replug) as root/sudo,,, lsmod | grep ath ,,, ifconfig If it doesn't show with lsusb, check the other port, for me, hexdump's dtb conflicts usb2 and debug, doesn't work,, and usb3 locks hub on a daily basis, needs a replug, 3 different hubs Haven't tried easyb's dtb yet
  5. I am wondering what version of linux is this running under? I am not familiar with libre-elect
  6. >I have tried the conversion from dts to dtb but i not have success. Try again,,, dtc -h,, must be dtb,,, dts is only for editing/altering,,, kernel wants dtb Let us know how it goes Because of the symbolic names, if you don't have a compile environment it probably won't work
  7. I guess you have not read much of this thread, last5-6 pages would be good t9.dtb for 4.4.x kernel seems OK, I have not tried any 5.x, slightly different dtb (guess) Not on ups, 10d uptime,, H96max+, wifi dongle a bit unstable, needs powered hub, x11vnc Oh, and if hub back-feeds (many do) must unplug for reboot or power off For example, a 2 second power "blink", you will think box is dead, until you unplug hub power too
  8. @hexdump Thanks for your t9.dtb,, works fine with H96 max+ for me I could never figure out how the regulators worked, somehow you did Only thing lacking is module for SSV6051 I guess I should try to put patch in right place and make a kernel
  9. Board is labeled RK3328_8D4_V1.1, same as yours, wifi chip is indeed different, SV6051P Serial connection as shown in your photo I think the problem with sd card is power to socket, if you read this thread I have a few posts previous
  10. I have H96 max+,32gb, board is same, wifi is sv6051, no bluetooth Like you, most of the dtb give root fs not found, no /dev/block/mmc.... ,, or for the android versions a black screen, serial shows only a few lines of kernel load (<5) --edit-- you can make it work by writing image to both a uSD card and a usb stick, it will probably find the stick and run from it. The uSd can be small and slow Not so good with only 2 usb sockets
  11. Can you quote some specific models? My H96max+, android8.1 seemed OK,, SuperSU installed OK, root checker said all was well
  12. Err,, adb is not "android",, android is the graphical shell,, hypothetical example,, if you had firefox installed,, typing firefox in adb would NOT startup firefox But, for sure , adb is very powerful, despite being a considerable pain More on point, adb uses the su in /sbin,, android uses the su in /system/xbin,, it is no good
  13. Clearly,, you have not read whole thread,, about 5 pages back, but differently in adb# ,, ls -l /sbin/su; ls -l /system/xbin/su ,, notice that they are not the same? (google) verity off; mount -o remount,rw /system; cd /system/xbin; mv su su.bak; cp /sbin/su . and then root will work in android FWIW
  14. I have one of these, in the simple shell ls -l /dev/block will show at best mmcblk1 (the emmc), (almost) never the sd card I think it's something to do with the regulator,, pwm does not seem to work,, the android dtb seem to use simpleReg vrs rk805-regulator I did a "hack" bypassing gpio, barely works, lots of errors in dmesg (regulator errors,, boots and runs from sd) The other method is to copy rootfs to a usb stick, rename the partitions (e2label)
  15. Dmesg , if all is well, will give a message, ie (dmesg |grep firmw) usb 1-1.4.3: rtl8xxxu: Loading firmware rtlwifi/rtl8192cufw_TMSC.bin for a usb dongle
  16. Well, it varies, alas. The firmware files can be bin or fw or other. Usually from /lib/firmware or a folder there BUT can be in /usr/somewhere, this is not common I don't know how the ko knows where to find the firmware Firmware are for the wifi chip, are version and OS independent It is 1 of them, there are 9 or 10 in total plus uboot and miniLoader and ? Maybe I'm telling you something you already know, / in Android is only in mem, loaded from the boot part, a gz cpio. Most of the folders in / (android ) are links to the appropriate partition I would guess that these are the ones you need, try copy them to lib/firmware/rtlwifi
  17. As I said, usually an android dtb won't work for linux, but it is a guide on how to change an almost working dtb For wifi,, 3 things have to be "right". A reference in the dtb, a module, and the firmware You will really have to get dtc (device tree compiler) and learn how to use it, it is not that hard.. Harder is making the "right" device tree IMO,, you really should have a "perfect" boot with sdcard (everything works, no glitches) before thinking about overwriting emmc ----more-- For wifi the reference in the dtb is not at all important, only if you want it to work during boot. I have seen wrong wifi chip referenced in dtb, modprobe right module (if firmware is there) and the wifi works This assumes it is talking to the right gpio There is a discussion about that in this thread a few pages previous
  18. No, mmcblk0 is almost certainly your sdcard, just from the partitions on it It's really common for android to have boot0, boot1, rpmb on the emmc, that is likely where it is (blk2) If you have checked your evb.dtb by turning it into a dts, check dwmmc@ff500000, and @ff520000 for bus-width = < 0x04 >; or 0x08 and the aliases { ,, then you will know for sure You do know this will wipe out your android? Before you do that, it would be good to extract the android dtb because it is sometimes hard to get the right image for your hardware, there are so many slightly different images
  19. There are dozens of different tv boxes, easy to get wrong image, usually does not "work out" in output/Image (specifically my box, h96max+-ssv, from the vendor, ssv is wifi) ls -l *.img -rw-rw-r-- 1 d d 1048576 Nov 11 12:35 baseparameter.img -rw-rw-r-- 1 d d 1708536 Nov 11 12:35 boot.img -rw-rw-r-- 1 d d 19036180 Nov 11 12:35 kernel.img -rw-rw-r-- 1 d d 49152 Nov 11 12:35 misc.img -rw-rw-r-- 1 d d 168060 Nov 11 12:36 oem.img -rw-rw-r-- 1 d d 8971308 Nov 11 12:35 recovery.img -rw-rw-r-- 1 d d 5592576 Nov 11 12:35 resource.img -rw-rw-r-- 1 d d 1547079912 Nov 11 12:36 system.img -rw-rw-r-- 1 d d 4194304 Nov 11 12:35 trust.img -rw-rw-r-- 1 d d 4194304 Nov 11 12:35 uboot.img -rw-rw-r-- 1 d d 163962992 Nov 11 12:36 vendor.img and in output -rw-rw-r-- 1 d d 162126 Nov 11 12:33 boot.bin drwxrwxr-x 4 d d 4096 Nov 30 01:54 Image/ -rw-rw-r-- 1 d d 162126 Nov 11 12:35 MiniLoaderAll.bin -rw-rw-r-- 1 d d 724 Nov 11 12:35 package-file -rw-rw-r-- 1 d d 981 Nov 11 12:35 parameter.txt Still have to extract dtb from resource.img
  20. Ah, android.. No, if you run fdisk -l on your mmcblk2 file you will see 3 4mB partitions,, where is the rest?? 15 or 30 gB missing, right? The rest is in a mtd filesystem,, under the stanza "chosen" you may see something like this bootargs ......... mtdparts=rk29xxnand:0x00002000@0x00002000(uboot),0x00002000@0x00004000(trust),\ 0x00002000@0x00006000(misc),0x00000800@0x00008000(baseparameter),0x00008000@0x00008800(resource),\ 0x00010000@0x00010800(kernel)...and so on (#'s are blocks/sectors,,,, length@offset (+12M)) You want the first 70k of resource, starts 2k in, magic is 0xd00dfeed, about 64k long. The rest is 2 png or jpg, the splash screen, 1st is for 720p, 2nd (larger) for 1080p I don't know how to mount mtd filesystems, AND I have had no luck converting android dtb to linux dtb,, nothing that I have found on google either Usually it just doesn't boot, fails very early on kernel load (serial console) ----- but usually with these tv boxes you have root in adb,, have you tried? If so, cd to proc, somewhere in there is the device tree, use busybox tar and write it to sdcard, and then to your computer (on an ext fs), then expand and use dtc -fs on the expanded directory,, then you will have the android dtb Or,, easier, if you have adb root,,, find which partition resource is , /dev/mmcblk2p??? ,, dd 70k to internal sdcard (I think this is ext fs,, vfat will lose permissions etc) then to computer, chop leading 2k, trim excess from end (hexeditor and dd) BTW the reason adb has root but not android... the su in /system/xbin is no good,, the one in /sbin is the right one Use verity off to make /system rw, then you can mv xbin/su xbin/su.bak and /sbin/su -> xbin and then get su in android
  21. Err, I have a mt7601u,, 148f:7601,, I don't think it is so good,, in iwconfig I see Tx excessive retries:35031 Invalid misc:1837 Missed beacon:0 (this is with uptime 9d 13h)
  22. A bit late, but I have narrowed down the problem, for at least my TV box It is a problem with the regulators both linux and android have problems (at least their dtbs') linux uses rk805,, android pwm/simple with 805,, 00 1e 01 ,, sdio doesn't work, so no mmc (gpio, offset, function) sdmmc-regulator with pwm 02 04 01 and 02 05 01 half fails (there is power to cpu and not cooked),, no gpu and debugfs vdd-center, vdd-log That is why the liantong had mmc but no vid, uses pwm, same as any other android dtb I did luck into a blodge, works for armbian but not Balbes' TV (cut out gpio0, go directly to pwm, not sure what to do with pinctrl-0, sorta works) Clearly,, a dtb is a looong way from a bios,,, it would be really helpful if as much as possible,, if phandle , if they corresponded to real hardware, had the same value as linux devices,,ALWAYS Standards are a wonderful thing --later-- A report on new wifi-dev, No sd found for rk3328-8d4-v1.1 ,, h96Max+ of the 5 dtbs, both liantong and evb-android crashed z28 no mmc,,,. roc-cc emmc, no sd,,,, evb emmc, noticed sd but no p1,p2 no usb2 (phy-supply) --a day later-- wanted to try my "blodged" dtb,,,,,Unable to read file my.dtb but uboot ls saw it OK, had been lower-cased, so change extlinux.conf, , a uboot artifact, had NOT been lower cased,,, then tried one of the originals Unable to read file rk3328-roc-cc.dtb,, spelling correct,, uboot ls sees it ?????,, nothing on google
  23. And now, after trying about 20 dtb's, only the liantong (all 3) see mmc0 and mmc2 and the partitions (and despite running dtdiff until my eyes are crossed I don't see anything significantly different in dwmmc) Unfortunatly they all stop, about 4 seconds into the kernel load with rockchip-dmc dmc vop bandwidth to dmc rate (all 3 liantong) I don't think this is something tuneable in a dtb The post above, those are spurious error msgs,, but about 1/2 of all the others have (early,,8x) rockchip_mmc_get_phase invalid clock rate all those apparently dangling clocks point to the clock name, I have no idea what is in that I don't have enough hd space or a powerful enough box to compile, alas --edit-- the 2nd and 3rd liantong are essentially the same, only fastest cpu removed
  24. Bables,, after viewing about 20 dmesg logs, I see some things in common (re no mmc,, ls -l /dev/block) The 1 and only 1 showing any mmc was the legacy dev with roc-cc ,,Ubuntu_bionic_dev_4.4.161_desktop,, and I see rpmb, boot0 and boot1,, that's all I think lacking (in init) is rkpart for the rest of mmcblk0 (the emmc) Most dtb lack (in aliases) mmc0 = "/dwmmc@ff500000"; and so on This is an error in all? most anyway I don't know how severe this is (all? most) rockchip-dmc dmc: Cannot get the regulator "center" (missing stanza?) dwmmc_rockchip ff510000.dwmmc: No vmmc regulator found (also ff500000 and ff520000) dwmmc_rockchip ff510000.dwmmc: No vqmmc regulator found and minor error dwmmc_rockchip ff500000.dwmmc: num-slots property not found, assuming 1 slot is available and probably not related rk-vcodec ff360000.rkvdec: vcodec regulator not ready, retry many of the uboot are older, and for roc-cc --edit-- and yet, when I try with normal armbian (console=both) there are no errors in any dwmmc lines, but no mmcblk devices or partitions are discovered (except by uboot, kernel, initrd and dtb get loaded OK)
  25. I must say that I am most un-impressed with the dtb system I have been struggling with it for days, with almost NO success at first I thought I was a fuck-up none of my modified dtb's seemed to work, now,, after getting a serial connection (which is very little help, except for scroll back), I see that it is not me,, ** Unable to read file /dtb/rockchip/an-untouched-dtb ** and then the dtb',s every one different, pin#'s ,clocks, everything I even tried making a dtb -fs from a running android, (tarred /proc/device-tree) lots of errors in android dmesg, a wonder that it booted, and then edit androidisms out,, that didn't work either What a pain,, I'm starting to think this is more trouble than it is worth --edit-- It could find the dtb, previous 2 lines retrieving file,, reading file oops the retrieving and reading lines were in error, the file didn't exist Too many different versions, easy to lose track
