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 (50.3 KB)
xavier-flash-devkit.txt (61.1 KB)
Please check the uart log on device side when it got stuck.
hello WayneWWW：
here is the uart log

Hi,
There is a eeprom.cvb_eeprom_read_size = 256 in below file, please change it to 0 and flash your board again.
tegra194-mb1-bct-misc-l4t.cfg
hi WayneWWW:
I have change below files
bootloader/tegra194-mb1-bct-misc-l4t.cfg
bootloader/t186ref/BCT/tegra194-mb1-bct-misc-l4t.cfg
eeprom.cvb_eeprom_read_size = 0
but it does not work
Hi,
Which board config are you using to flash your board?
Could you also modify that one in below file?
tegra194-mb1-bct-misc-flash.cfg
hi WayneWWW:
it is out customer board,there are some diffs IO with devkit;
I also modify that one in below file
bootloader/t186ref/BCT/tegra194-mb1-bct-misc-flash.cfg
bootloader/tegra194-mb1-bct-misc-flash.cfg
I mean which command do you use to flash the board? And is the uart log still showing same error?
command is ./flash.sh -r jetson-xavier mmcblk0p1
the uart log is not same
xavier-log1.txt (3.6 KB)
r jetson-xavier mmcblk0p1
Could you also share the same module’s uart log when it is flashed on devkit? Thanks.
Hi,
Didn’t you say devkit can pass the flash procedure?
hi WayneWWW:
i test
if modify
bootloader/tegra194-mb1-bct-misc-flash.cfg
bootloader/t186ref/BCT/tegra194-mb1-bct-misc-flash.cfg
eeprom.cvb_eeprom_read_size = 0;
the devkit can not boot too!
if modify bootloader/tegra194-mb1-bct-misc-flash.cfg
bootloader/t186ref/BCT/tegra194-mb1-bct-misc-flash.cfg
eeprom.cvb_eeprom_read_size = 256;
the devkit can boot!
Ok, could you share the uart log with the original setting?

Hi,
We will check this internally and update later. Sorry for inconvenience.
And just to confirm, is your carrier board fine if using jetpack4.x?
hi WayneWWW:
I check the schematic diagram,our customer board does not have an EEPROM,
the boot source code whether release later?
BR
thanks
Hi,
It is okay that your board does not have EEPROM. I just want to make sure whether your board is okay with jetpack4.x.
The boot source won’t be released. So only I can help you at this moment.
