I am using the Jetpack 6.2 SDK to flash the Orin NX core board. When I use the devkit, it can be flashed normally. However, when I use the customized carrier board, it stops at booting into RCM mode. Our carrier board completely follows the devkit design for the USB part for flashing.
The flashing command I am using is：
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-super internal
The log printed by the flashing terminal is as follows:

May I ask what could be the reason that the BL cannot enter RCM boot mode? Does the EEPROM on the Carrie board need to be programmed with additional firmware?
Please guide me if there is any issue with the operation. Thank you!
