flash.sh: Flash the target board.

flash.sh performs the best in LDK release environment.

Usage: Place the board in recovery mode and run:

flash.sh [options] <target_board> <root_device>

for more detail enter ‘flash.sh -h’

Examples:

./flash.sh <target_board> internal - boot <target_board> from on-board device (eMMC/SDCARD)

./flash.sh <target_board> external - boot <target_board> from external device

./flash.sh <target_board> mmcblk0p1 - boot <target_board> from eMMC

./flash.sh <target_board> mmcblk1p1 - boot <target_board> from SDCARD

./flash.sh <target_board> sda1 - boot <target_board> from USB device

./flash.sh <target_board> nvme0n1 - boot <target_board> from NVME storage device

./flash.sh -N :/nfsroot <target_board> eth0 - boot <target_board> from NFS

./flash.sh -k LNX <target_board> mmcblk1p1 - update <target_board> kernel

./flash.sh -k EBT <target_board> mmcblk1p1 - update <target_board> bootloader

It is the log file of it

Is this all command for eMMC jetson or SD CARD slot jetson?
As I have Jetson with SD card slot

[WayneWWW]

I read your flash log. Your Jetson Nano is actually not a NV devkit.

It has emmc on it. Please read this again.

If that is 4gb module, then please use sudo ./flash.sh jetson-nano-devkit mmcblk0p1 to flash first. If it fails, try sudo ./flash.sh jetson-nano-devkit-emmc mmcblk0p1

If you don’t know why it is a eMMC module instead of sdcard module, read below post.

https://forums.developer.nvidia.com/t/guidance-to-tell-if-you-are-using-a-nv-developer-kit/316012/5

Also, I want to say this one last time.

If you want to share any log, share that as text log instead of screenshot.
We need full information instead of the partial info on your screenshot.

L4T BSP Information:

R32 , REVISION: 7.6

Error: probing the target board failed.
Make sure the target board is connected through
USB port and is in recovery mode.

while running emmc this thing is comig while the board is in recovery mode

Is your sdcard slot on the carrier board or it is on the module?

If you don’t know what I am talking about, please take a picture of your board. Especially the sdcard location.

[akshatmishra.8462]

[WayneWWW]

Yes, the sdcard slot is on the carrier board but not the module.

This is definitely a eMMC module.

The flash command is correct. Your board is probably not in recovery mode correctly.

[akshatmishra.8462]

[WayneWWW]

recovery mode only lasts for one flash attempt.

If you want to flash again, you need to put the board into recovery mode again.

[akshatmishra.8462]

It is flashed correctly but the NVIDIA logo still stucked in

[akshatmishra.8462]

What next step should I do

[WayneWWW]

please enable serial log for us to check.

Follow this page.

Jetson Nano & NX Style - Serial Debug Console - JetsonHacks

[akshatmishra.8462]

It’s a good method but can u tell its alternative as for this TTL is needed and I don’t have TTL?

[WayneWWW]

no, there is no other method. This is the only method to dump boot log
