I have a custom carrier board that allows me to use Xavier NX and Nano
I tried to flash the Orin NX 16gb module using this board. (Jetpack 5.1.1)
Failed as a result. If you check the log, it seems that the Timeout occurs while waiting for the board after Flash.
This is log result of SDK Manager.

This is log while board booting

Before flash, I adjusted the eeprom read size according to this document.
I changed the
cvb_eprom_read_size from all *.dtsi, *.dts, and *.cfg extension files under the bootloader folder to 0 or 0x00.
(in ~/nvidia/nvidia_sdk/JetPack_5.1.1_Linux_JETSON_ORIN_NX_TARGETS/Linux_for_Tegra path)
Finally, below command worked for me, and I succeeded in flash.
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml” --showlogs --network usb0 p3509-a02+p3767-0000 internal
What is the meaning of cvm, cvbeeprom size,
and what are the possible side effects of modifying it from 256 to 0?
