  1. It's looks like I'm wrong. If it's mentioned on the download page then there is support. I'd give it a try. Cheers, Steven
  2. Hi, I don't think that Armbian supports the Nano. I've managed to get my Nano running (except for power-off) with the standard kernels (e.g. 5.16.11) but if you need the Nvidia graphics driver then I think you're stuck with the 4.9.253 kernel supplied by Nvidia. Also, it's not as easy as you might expect to update U-Boot. I'm assuming you have a Nano developer kit where the board has 4GB flash and an SD-card. U-Boot does exist on the SD-card but if you reload the relevant partition you'll also need to update the checksum at the start of the partition. I've tried to work out how to calculate the digest but given up and it seems to be an Nvidia secret. Regardless of this, the boot code on the card isn't used anyway. The boot sequence runs tboot, then cboot, then U-Boot. But all these files are sourced from the 4GB flash rather than the SD-card. It is possible to write to the flash but again the relevant checksum must be written. The code to do this is probably buried in some of the Nvidia x86 programs but these are not open-source. Back in the L4T 4.4 days the boot code sourced U-Boot from the SD-card. But when L4T 4.6 came out the process was changed and U-Boot was added to the flash code and cboot changed to read U-Boot from this flash partition. So changing U-Boot requires re-flashing the relevant partition. All the above is from my research and might not be correct. The Nano is quite a powerful little board but unless you need the Nvidia AI specials then maybe it's not worth playing with due to all the Nvidia specials. If anybody here knows the checksum algorithm then please let me know. Cheers, Steven
  3. Hi, Thanks for the tip. I've added "system-power-controller" to the 77620 node but it has no effect. The Nvidia kernels contain driver code for the "tmpm32xi2c" which seems to be associated with system power. But there is no such code in the standard kernels (e.g. 5.16.5). This is why I was asking if people here were using a standard kernel or a modified one. Cheers, Steven
  4. No, the log is what happens with all the 5.1x kernels (including your 5.10.60 and 5.16.4). The Nvidia kernels (4.9.140 and 4.9.253) do power off the Nano correctly. What I've noted here is that the "Tegra System Off: operation not handled." message appears in the Nvidia cboot code which is in one of the partitions on the SD card and also in the later versions (e.g. 4.6) of the code in the QSPI EMMC.
  5. Hi, Thanks for your work here. I've been playing with the 5.1x kernels on my Jetson Nano and using your configuration has solved some problems for me. One outstanding issue is that I can't power the unit off. "halt -p" goes through the shutdown motions but I end up with the error list below. The standard Nvidia 4.9 kernels do work here.

Are you using the standard kernel or are patches required ? Thanks, Steven
  6. Hi, Great news that you've got somewhere. With the "eth0" name being changed to "eth............", this occurs because the kernel (or udev or something) wants to include the MAC address in the name. This can be stopped by adding "net.ifnames=0" in the kernel bootargs command line. I was chasing a bad idea because I figured your board was an "HC2" and U-Boot was intended for an "xu4". But apparently they're the same or compatible at least. But note the single line "if" test under the 4 lines that set fdtfile for various boards. It's a long line that checks for a file called ".next" and if it's not found the code sets fdtfile to ".....xu3". The check for whatever file was 88701 bytes was a clue. As you say, adding a dummy file called ".next" to your /boot directory probably would solve the problem here. From a software distribution viewpoint I would add the "net.ifnames=0" to the bootargs so the DEVICE= clause doesn't have to be changed for every board and the standard "DEVICE=eth0" should work for all boards. Also I don't see why the ".next" file is missing. Most Armbian distributions contain such a file (size 0) and this is detected by the U-Boot script and tells it to use the mainline kernel (and ....dtb in your case). But it's great that it's working now so I'd leave things as they are and all the work you've done will help anybody else that hits the same problems. Cheers, Steven
  7. Hi, In one of your previous posts you listed some U-Boot code that changed the fdtfile variable depending on the board name and you noted that your board wasn't mentioned. The U-Boot log shows it is loading a flattened device tree file that is 88701 bytes long. Can you check in your /boot/dts directory and check if the .dts file for your board is 88701 bytes ? Somefile.dts files provide hardware details for the drivers and using the wrong one might cause all sorts of problems. What I.m checking here is that U-Boot is loading the correct .dts file for your board. -- Steven
  8. Hi, Good to see you've got the monitor. Can you check that the correct .dts is being loaded ? See if the one you should use is 88701 bytes ? If not you could override the choice in boot.scr (setenv fdtfile .....). Cheers, Steven
  9. Hi, What OrangePi board do you have ? I have an early model OrangePi A20 board and the .dtb you mention does work, This is when using a 5.x.x kernel. It will also run with an old 3.4 kernel but this doesn't use a .dtb and I don't think the standard boot.src will boot it anyway. Cheers, Steven
  10. Granted it's not a very attractive suggestion. It does involve purchasing a specialised device and then learning how to use it. And it won't actually provide a solution, just some clues hopefully. Can you download the software release again and try with a different uSD card ? Or just try some other release to verify that the hardware is okay ? Cheers, Steven
  11. Hi, The M=/sr/src/... looks wrong to me. Shouldn't it be M=/usr/src/... ? Update: I think that this make has to be done on the system that built the kernel. This was the case with the old Realtek drivers I built for RPi kernels. The make needs a valid "build" softlink in the modules directory. This softlink is only valid where the modules were created. Cheers, Steven
  12. Hi, I think you need a serial cable connected to the UART0 port (try 115200 8N1). This will show you the U-Boot output. The U-Boot output should end with "Starting kernel ...". If you see nothing after this then either the kernel isn't starting or its bootargs are specifying the wrong console for output. The primary console in the bootargs should be "ttyS0,115200". I hope this helps. I don't know the board and are assuming it uses the standard Armbian boot script. Cheers, Steven
  13. Hi, Thanks for the pointer to the patches. I've applied some to the Denx master and it now works. I suspect the clock patches were the critical ones. Cheers, Steven
  14. Hi, I'm trying to generate a U-Boot for my OrangePi Plus board (H3). I'm using the Denx 2021.10 release and have tried the standard defconfig for this board and also variations of this config. Starting the kernel is fine but the kernel crashes/hangs when starting if I'm using HYP (nonsec) mode. Starting in sec mode works but this only enables one of the four CPU cores. The kernel crash/hang occurs while executing "udevadm trigger --action=add" but I can't determine exactly what is being enabled when the error occurs. Trying different kernels (including the Armbian 5.10 version) show no difference. The Armbian U-Boot (2021-10 dated August 2021) does work but I can't get a similar version even when I use the Armbian config from apt.armbian.com. Can anyone provide a link to the Armbian source so I can find out what has been fixed for this H3 board. Perhaps a board_init function has been added. Thanks, Steven
  15. To enable U-Boot to boot an old kernel the U-Boot option CONFIG_ARMV7_NONSEC must NOT be selected. I suspect it is selected in the Armbian U-Boot. There is also the CONFIG_OLD_SUNXI_KERNEL_COMPAT option that apparently slows DRAM access and is sub-optimal for new kernels. I've tested with this option not selected and the OrangePi A20 board here works fine with both old and new kernels booting with this new U-Boot. Cheers, Steven
