Jetson nano reflashing fails

Autonomous Machines Jetson & Embedded Systems Jetson Nano
1

Hi There,

I have been trying to reflash my Jetson Nano B01 for a few days, after it didn’t boot, anymore.
I tried both using SDK manager and directly using the instructions of the l4t_quick_start guide.
The output log of the latter is posted below.
I already followed other posts by including the board id and FAB in the p3448-0000.conf.common path , which allowed the flashing procedure to start but still fail as shown below.

Failed flashing t210ref.

Lastly the Error from the SDK manager was as follows:

15:31:17 ERROR: Flash Jetson Nano - flash: --- Parsing board ID (ERROR: calculated CRC8 0x5b != stored CRC8 0x5) succeeded.

Hope anyone can help me out

Did you add the board ID into the xml and include the xml to your board config?

3

I did, I also tried setting FAB to both 000 and 400, but both didn’t work

4

Hi,

Could you provide more detail about current status instead of “didn’t work”? You can try to provide current log so that it might give hint.

Also, share all the things you have changed so far.

This will be better than only saying “this cannot work”.

If eeprom is already corrupted, you don’t need to try sdkm anymore. It won’t bring it back. Only flash.sh has chance.

Hi Wayne,
I’m sorry if I was not clear.
Since I already added the board ID into the xml file and the xml file into the board config in my first post, the log remains the same.
To the p3448-0000.conf.common file I added these lines:

BOARDID=“3448”;
FAB=“000”;
BCFFILE=“bootloader/${target_board}/cfg/board_config_p3448.xml”;

To the board_config_p3448.xml file I tried changing the Fab from 0 to, 000, and 400, but the output log remained the same as my first post. :
<board type="proc" id="3448" sku="0000" fab="000" />

6

HI,

Does your Linux_for_Tegra have a binary called cvm.bin? If so, could you use chkbdinfo tool (also inside Linux_for_Tegra) to read out this cvm.bin?

7

Running the following command inside the bootloader folder:

./chkbdinfo cvm.bin

Outputted this:

ERROR: calculated CRC8 0x5b != stored CRC8 0x5

This looks like the same error that I got from SDK manager which I posted at the end of my first post.

8

Just want to know, is your board still able to boot up?

9

No it isn’t that is why I wanted to reflash it

10

Could you also dump the uart log when the flash process is running?

If the flash.sh does not complain your CRC is incoreect, I feel the cause might be something else. For example, the board ID/sku/FAB provided is not correct.

11

I just ordered the cable for that and it will arrive in the mail in a few days, I will respond the uart log as soon as I have it.
