How did you dump this log? I mean under what kind of situation?
This looks like a boot log but not flash log. Recovery mode is to put device into a status that can get flashed.
And it has nothing to do with the software running on it. This process is totally a hardware triggered case.
I mean even the emmc is totally formatted, it should still be able to get flashed.
hi,
I got this log by connect the UART pin of the 40-pin exp header on the carrier board to my computer and use minicom software to read the output on Linux. right now, I can not force into recovery mode by pressing the switchs on the carrier board. I think to force into recovery mode, the bootloader must be running first, but from the log, it seems my bootloader is broken and it can not run. maybe i am wrong. I think I have to fix the boot software so I can get into recovery mode and then flash os, but I have no idea what to do
but I have another four tx2, all of them can get into recovery mode with my steps, and every day i would flash os into the board several times, and they all succeed. Why only this board can not work? Or did my board have hardware damage ?
Can we do some cross check by switch the carrier board and module here?
For example, you have 4 normal TX2 and 1 NG TX2, how many carrier board do you have? Is it possible to take the NG TX2 to the carrier board of other normal TX2 and then try to flash?
Also, can you describe how you put device into recovery mode?
thanks, I have 4 third-party carrier board and 4 original nvidia carrier board and I have already tried to switch the carrier board, and it did not work.
my steps is, press the power switch then press the recovery switch and hold it, and wait for about 5s~7s, then press the reset switch and wait for 3s ~ 5s then release the recovery switch
