Hi: I am attempting to flash a Xavier for operation with a custom carrier board. During flashing, the process hangs at the tegrarcm_v2 --isapplet stage. What could be causing this to happen? and at the same time I test on xavier devkit,it’s ok below is the log: xavier-flash-custom-board.txt (50…

Since jp5.0 DP is just developer preview, please try with devkit only. This issue would be fixed after jp5.0 GA.

according to the threads: https://forums.developer.nvidia.com/t/jetpack-5-0-dp-ethernet-port-rgmii-not-working-with-ksz9031/211097 https://forums.developer.nvidia.com/t/cannot-reflash-agx-device-incorrect-eeprom-values/211428 https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driv…

I tried the suggestion from this thread and only commented out the eeprom section of tegra194-mb1-bct-misc-flash.cfg, left other cfg files unchanged. Flash completes, but boot fails with different errors: .... [0068.289] I> Writing VER partition. [0068.292] I> Writing device 1: 3. [0068.296] I> Wr…

I find out only modify “EEPROM section” statements at last only in these files: bootloader/t186ref/BCT/tegra194-mb1-bct-misc-flash.cfg bootloader/t186ref/BCT/tegra194-mb1-bct-misc-l4t.cfg the flash.sh works well on my custom board. eeprom.cvm_eeprom_i2c_instance = 0; eeprom.cvm_eeprom_i2c_slave…

ok, I tried the suggestion to only modify bootloader/t186ref/BCT/tegra194-mb1-bct-misc-flash.cfg and change the two lines from 256 to 0. Still can’t boot, but with different errors from uart: ...

I think you need to know the hardware architecture of your board first, some custom board use eeprom not in tegra offical way. According to your log before , I guess r34.1 jetson uefi need to read from eeprom to get hardware information like MAC/Wifi/Bluetooth. When commenting out all eeprom section…

eeprom is not used in custom board. Based on this post , This is not a mandatory design. Most of custom boards from other vendors don’t even have such eeprom on their board.

Have you also changed bootloader/t186ref/BCT/tegra194-mb1-bct-misc-l4t.cfg but not only that one with “-flash” in the file name?

Hi All, I replaced all the tegra194-mb1-bct-misc-X.cfg files as below, AGX flash and bootup on our own carried board success. EEPROM flags eeprom.cvm_eeprom_i2c_instance = 0; eeprom.cvm_eeprom_i2c_slave_address = 0xa0; eeprom.cvm_eeprom_read_size = 256; eeprom.cvb_eeprom_i2c_instance = 0; eepro…

Thanks for reply @Luna2020 . Is there any problem on the board after you did that? For example, whether the ethernet fails to get mac address, something like that. The mac address is from cvm eeprom, so I want to make sure that is still working or not.

Hi WayneWWW, I’m testing now, the ethernet failed to get mac address and can’t make ethernet connetion. [ 9.551292] nvethernet 2490000.ethernet: Adding to iommu group 30 [ 9.560207] nvethernet 2490000.ethernet: failed to read skip mac reset flag, default 0 [ 9.575614] nvethernet 2490000.e…
