Our team has been using the Orin Nano SOM on L4T 35.5.0.
We have been notified of a change to new Micron DRAM (as part of PCN212822), and have received these new SOMs as part of testing.
Basically we have to extract new BCT and DVFS files (t234-dram-package-35.0.0_2024-09-18.tbz2) to our “Linux_for_Tegra” folder, and then flash the SOM again with these files. In addition, we have fuses burned onto each SOM. I connected this Orin Nano SOM with new DRAM to our Linux PC with the Orin Nano Dev Kit, and attempted to run these commands:
- tar -xvf t234-dram-package-35.5.0_2024-09-18.tbz2
- sudo ./odmfuse.sh -i 0x23 -k rsa.pem -S sbk.key -X fuse.xml jetson-orin-nano-devkit
- sudo ROOTFS_AB=1 ./tools/kernel_flash/l4t_initrd_flash.sh
–network usb0
-u rsa.pem -v sbk.key -i sym2_t234.key
-p “-c ./bootloader/t186ref/cfg/flash_t234_qspi.xml”
–showlogs jetson-orin-nano-devkit internal
Unfortunately, I am not able to burn the fuses on this SOM, and subsequently cannot flash the img either.
Is there a step that I am missing? I attached UART and terminal logs to this ticket. Please let me know if I am missing anything.
