    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

    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

    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

    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

    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

    Cant connect without ethernet

    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)

    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

    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

    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)

    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

    Bables for your next update,, this is from android kernel config CONFIG_SSV6051=m CONFIG_SSV6051_P2P=y CONFIG_SSV6051_SDIO=y because my H96Max+ has a SV6051P chip thanks

    Sorry, looking at dmesg (android) firmware is in /vendor/etc Yesterday,, another non-booting dtb, grr

    nytoc,, by the way, most firmware is distro and version agnostic ,, byte-order certainly matters, but probably not arch Sometimes it is in non-default locations and doesn't load, sometimes the package manager forces unnecessary restrictions sometimes ethernet has firmware --more-- Since you have a rooted android?? ,, you already have the firmware,, /vendor/lib/firmware/some-directory-with-8723-in-it's-name

    >Did you check if any mmcblk0\1\2 appeared ? I don't understand what you mean here? This was under rooted android,, so if I wanted to I could have dd'd them somewhere Under your distro, I have never seen any mmc devices, bad dtb I think >You need to try the tools to extract the firmware file. Maybe then you can get the dtb. You mean fdtdump? Initially, did not work, had to strip leading 2k to magic d00dfeed So far, all the dts that I have looked at are a MESS, pointing to non-existant clocks, phandle confusions, missing lines etc. It's a miracle that they boot Like there is 100 years of cruft in them, hard to believe these are newish devices if you can get a boot,, dmesg> to-something-to-study,, lots to fix (the initrd has dmesg in it, but unless it recognizes a usb stick you nowhere to write to) Nytoc, is the wifi loading the firmware?, dmesg | grep firmware Balbes's distro doesn't seem to come with firmware, apt-get
