Custom Board always in Force Recovery Mode

Hi
we have made a custom board using Tegra TK1. We have just done memory characterization and trying to flash L4T.
we have successfully reached till the step where log shows Boot downloaded successfully but getting an error at system.img (which is the last step during flashing)
error: failed flashing Ardbeg (seems USB problem according to related questions on the forum)

Now my question is that when we power up our board, it always remains in force recovery mode, even we do not press the force recovery button. is it a normal thing or there is some problem with the board.
Do you have any idea?
Thank you

Hi, can you please post full log of download here?

Could you share what have you done for “memory characterizatio”?

yes, I tested memory characterization by running “runme_instead_TK1_Full.bat”
and tested at 204MHZ. I shared my logs and config file at this thread.

if you need more information, please let me know.
Thanks

Does your flash procedure always halt at the same line with “4194304” bytes send?
Is this flash package working okay on original tk1 board?

no sir, it halts at different bytes. but there are some 3 or 4 different values at which it halted.
we have not yet tested it on original tk1 board.

Not yet have any idea. Could you describe what have you changed between original tk1 board and your board?

I have just changed DDR. I created a config file by creating its param file using memory characterization.
I updated the config file name in jetson-tk1.conf in Linux for Tegra directory.
These are the only things that are changed from the original procedure and board.
The part number for the DDR I am using is
MT41K256M16TW-107 AUT:P
we have also tried flashing using HUB but no still no luck. If you have any suggestion, please let us know.
Thanks

Do you use your own BCT? Why I saw there is " --bct PM375_Hynix_2GB_H5TC4G63AFR_H5TC4G63CFR_RDA_924MHz.cfg" in your log?

actually, I rename my BCT with this name instead of changing in jetson-tk1.conf
but I also tried by replacing my BCT name in jetson-tk1.conf, I am getting the same results.

I also notice your system.img is larger than our original one from jetpack.
Could you try to use your package on our board first?

Hi!
I have tested the same thing on Jetson TK1 kit. It flashed successfully and it is booting successfully.
I can send you logs if you want to see.

Hi!
Sir, I want to tell you that we have also the different part number for eMMC.
RP-SEMC32DA1
it is of 32GB, do we need some changes in uboot for this or it required any additional test for eMMC as we do for SDRAMs ?

How about flashing the default rootfs from jetpack?

I am following this to flash and getting the error in the custom board as I discussed

https://developer.download.nvidia.com/embedded/L4T/r21_Release_v7.0/l4t_quick_start_guide.txt?DfSKuMq7IfQohBMhjr_YEYJGgSidHHxg9Pa6EFukA9Nb1Zvli6MaoJIzfFaOOD-72s1zX6C3xaOZBbcvEr_K5TK67Nhz8O-CNA-_AnswyGuT4I4WGYFEC1eNvPCxQnrL725prZVX3a5gM5YX7GeJC4WY9ZPF3g

and following the same thing on jetson kit, I was successful. my custom board does not have ethernet so I may not be able to follow jetpack documentation.

Let me check with internal team with eMMC first. Have you done any test on eMMC? or only shmoo on SDRAM?

No, i didn’t run any test for eMMC. Please let me know if any required.

From current log, your device does not enter below line. Not sure whether CPU starting is failed or not. Still checking.
