I am unable to power on the TX2i SOM by using the TX2 development kit. I have checked the development and its working satisfactorily. Kindly assist in trouble shooting the issue.
TIA
Hi,
Do you mean there is no power on or you are saying that it is powered on but the system does not boot up?
Or you cannot tell the state?
The board is getting power, but the SOM isnāt booting. Is there a way to check if the SOM is powered on?
Hi,
Can you tell me how to do that? Currently my PC doesnāt detect the board with the TX2i when connected via both ethernet and USB-UART at J28. The following is whats seen with the regular tx2 on the dev boardā¦

Hi,
Iāve checked with the Tx2i SOM, nothing happened when powered On. Iām enclosing the dump from a working SOM to show that the board worksā¦
The oldest data was removed. Continueā¦

Hello,
Then I guess maybe this board has defect. Do you have only one TX2i module to test?
BTW, can you try to give the log in a format that is better to read? You can refer to how other users log look like.
Hi,
I had bought 10 Nos. of TX2i SOMs and all of them are exhibiting the same behavior. I have a couple of older Tx2i SOMs that were purchased earlier. These are working fine with the development boardā¦
Ok. Then that sounds not a hardware defect.
Are you able to flash those modules with this carrier board?
Yes, I was able to flash the older TX2iās to the latest Jetpack version using the boardā¦
Hi,
And what happened to the new boards?
I have been able to successfully flash 3/10 SOMs using the SDK manager. Will complete and check the remaining 7 shortly.
Thanks for the help.
Please check the devkit user guide. If your dev kit is B02 or B04 revision carrier board, it can not support TX2i module.
I have both the B & C series boards. Current issue was observed on the C series board, but funny enough I am able to use my older TX2i SOMs on the B series boards as well.
Can you share the part number of new/old TX2i module and carrier board?
I see a lot of serial nos. on the board. The Tx2i SOM bears the the model no.: P3489 and SN:0420418026387
There are some sample part numbers in this site:https://developer.nvidia.com/embedded/faq#jetson-part-numbers, you can refer to that to list the SKU and SN of new & old TX2i module and your B an C carrier board.
old SKU kit: 945-82771-0000-000 Y
new SKU kit: 945-82771-0000-000 AY
Hi, I am a little confusedā¦
Do you have two kinds of TX2i module (SoM), new and old, right? If so, please list the SKU and SN of them.
Also please list the SKU and SN of the ādevelopment boardā that old SoM can work on.
