Hi shrinathchoudhary,

Are you using Driver Package or JetPack to flash?
We’re release JetPack-4.2 last week, please also try this one. Thanks!

SDK Manager: [url]https://developer.nvidia.com/embedded/dlc/nv-sdk-manager[/url]
Install guide: [url]http://docs.nvidia.com/sdk-manager/install-with-sdkm-jetson/index.html[/url]

shrinathchoudhary · March 28, 2019, 9:32am

thanks for the reply.

I tried both, using jetpack as well as driver package command line to flash. but i’m getting same result as mentioned in my post.

please provide me the link to jetpack 4.2 download.

please note:-

my tx2 devkit is not connected to any router switch or dhcp network through ethernet cable…
is this making flashing issues?

carolyuu · March 29, 2019, 6:25am

Hi shrinathchoudhary,

The latest JetPack-4.2 is using SDK Manager to install.
Please check install guide first. Thanks!

FYI, flash itself never requires network. Flash does require the micro-B USB and the Jetson in recovery mode. The host PC should not be a VM.

Andrey1984 · March 31, 2019, 8:10am

It seems that Jetpack 4.2 supports TX2.
Will worth trying updating my TX2 with it.

shrinathchoudhary · April 1, 2019, 5:35am

My host pc is not a VM.

tried with jetpack 4.2. still facing same issue “parsing board information failed”

please find the log for jetpack 4.2.

Please check the if there is a existing cvm.bin file under your bootloader folder.
If it does, it may indicate the EEPROM content on your cvm is not programmed correctly.

Is it a fresh out-of-box tx2?

shrinathchoudhary · April 1, 2019, 6:57am

Hello,

cvm.bin exists under bootloader/.

and yes it is a fresh out-of-box tx2… first time when power on my tx2 , followed the instructions promted to execute “installer.sh(l4t_28.1.0)”

now when I’m trying to flash, it is failing…

how to program EEPROM content properly so that it can flash my tx2 ?? or what is the solution?

thank you

WayneWWW · April 1, 2019, 7:50am

Have you ever flashed or boot into device successfully?

shrinathchoudhary · April 1, 2019, 8:55am

No… never flashed before. this is first time im flashing.

every time when powered on, it will boot from emmc or SD card successfully.

in between i tried to read eeprom from i2c bus 2 at address 0x50 which is connected to EEPROM

i2cdump -y 2 0x50

o/p is “xx” in all 256 bytes

referred this link :-[url]https://developer.nvidia.com/embedded/dlc/tx1-tx2-module-eeprom-layout[/url]

but when i read i2c bus 7 at 0x50 address,it is displaying actual EEPROM content, which matches to the layout of EEPROM given in above link.

shrinathchoudhary · April 1, 2019, 9:41am

it is specified that on module EEPROM will be connected to i2c bus 2 in the documents provided by nvidia, but when we tried there is no devices connected to i2c bus 2. Instead we are able to find EEPROM connected to i2c bus 7.

By default if board trying to get information from EEPROM connected to i2c bus 2, there is no EEPROM device, do we have provision to change that option? can we make it to get information from i2c bus 7 instead of i2c bus 2.

or there is any other way to skip the reading information from EEPROM and can we change it manually?

thank you,

WayneWWW · April 1, 2019, 9:45am

Hi,

Actually it should be i2c bus7. I would like to know what document indicates bus 2.

shrinathchoudhary · April 1, 2019, 10:15am

please refer the link provided

[url]https://developer.nvidia.com/embedded/dlc/tx1-tx2-module-eeprom-layout[/url]

In that it is specified that EEPROM connected to i2c bus 2.

If i2c bus 7 is correct then why flashing is failing after reading data from EEPROM? it is giving following error

10:54:52 INFO : Flash Jetson TX2 : Parsing board information failed.
10:54:53 INFO : Flash Jetson TX2 : exit status 1

WayneWWW · April 1, 2019, 10:38am

Got it. bus2 should be for TX1 but not TX2.

Please double check the value in byte 255, which is the CRC value. If the crc value is incorrect, you still cannot flash the board.

The calculation for this crc value is also on the document.

shrinathchoudhary · April 2, 2019, 5:06am

thank you so much @WayneWWW

due to mismatched checksum, it was failing.

run the following command from bootloader/

./chkbdinfo -i cvm.bin

checked crc mismatch

updated eeprom as

i2cset 7 0x50 0xff $chksm_calculated_val

then tried flashing.

it was success.

shrinathchoudhary · April 2, 2019, 5:08am

thank you so much @WayneWWW

due to mismatched checksum, it was failing.

run the following command from bootloader/

./chkbdinfo -i cvm.bin

checked crc mismatch

updated eeprom as

i2cset 7 0x50 0xff $chksm_calculated_val

then tried flashing.

it was success.

@WayneWWW Hi,Wayne. I now meet the same problem (CRC check failed when I flash Jetpack V44 into TX2 devkit ).Before my ex-colleague worked with the TX2 devkit,but he left and I don’t know whether he modified the EEPROM/i2c. Do you have any advice for me? Thanks. The first pic is my host machine chkbdinfo error. The second pic is EEPROM content.

Hi,

What he modified does not matter. Just recalculate the checksum and write to bit 255.

Thanks. I change the CRC checked code at i2c 7 0x50 0xff to 0x5b,it works.
