When the kernel oops or panic, How can I falsh a new correct kernel image?

[Evil_mage]

When I debug the driver, And I try to printk the driver name, a access null pointer error appeared。

Then I correct the error, use the following command to flash a new kernel:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
  -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" \
  --showlogs --network usb0 jetson-orin-nano-devkit internal

I know the kernel cannot enter rootfs, so the process of flashing stop.
SO, How can I resume(flash) the jetson kernel?

I solved the this problem， when you are boot , pressed ESC:

select: Device Manager->NVIDIA Configuration->L4T Configuration->L4T Boot Mode

Default is “Extlinux”，Then change it to Kernel Partition.
This will boot kernel frome device not rootfs file(/boot/Image)。

Then，Flash the kernel only:

sudo ./flash.sh -r -k A_kernel jetson-orin-nano-devkit-nvme internal
sudo ./flash.sh -r -k B_kernel jetson-orin-nano-devkit-nvme internal

it will boot from the partition which you flashed just now.
