Jetson AGX Orin not reflashed again after editing /boot/extlinux/extlinux.conf

[vantai]

Hi there,

Our AGX Orin 32G was working very well. However, yesterday, we tried to to some operation to increase the USBFS buffer size permanently. Firstly, we do: sudo sh -c ‘echo 1000 > /sys/module/usbcore/parameters/usbfs_memory_mb’ after rebooting the USBFS go back to 16, so we managed to make a change permanently by:
Edit /boot/extlinux/extlinux.conf, add usbcore.usbfs_memory_mb=1000 to the APPEND line, and reboot the
system. Nonetheless, after rebooting the system, we could see only the NVIDIA window for a few seconds, then nothing came out ----> system not rebooted.
We have tried to following the flashing instruction again but SDKmanager not recognized the Orin again. Even our host machine could not see the Orin. Thus, the reflashing Orin was aborted.

Please let us know how we can solve this issue?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi, can you elaborate this section more?
Like, can you see the device with lsusb after putting it into force recovery mode?
Did you get anything from UART when trying to power it on?
