I followed the documentation Kernel Customization — Jetson Linux Developer Guide 34.1 documentation to build the kernel and ran into a problem at step 5 . [2022-09-21_10-59] But I can’t find the modules folder under this path. I have unzipped this archive Tegra_Linux_Sample-Root-Filesystem_R35.1.0_aarch64.tbz2“” and placed it in the rootfs folder. Do I need to do anything else?

Hi, The files are not open source, so you cannot build it. Please download a complete release as the base and apply your self-built kernel files.

Following the steps in document We have successfully compiled the kernel and replaced the image and device tree. But when i want to flash into the USB device ,it failed. [image] In the folders generating from SDKmanager,I flashed successfully using the same command

Hi, You need to use initrd to flash to external storage. Please refer to this README: Linux_for_Tegra\tools\kernel_flash\README_initrd_flash.txt

I have read this documentation and have successfully flashed to the USB device using the workflow11 command, under the folder generated by SDKmanager. I have followed the official documentation and link above to download the source code, compiled it successfully and flashed it to the USB but encountered the problem as shown in the picture. Please tell me how to solve this problem. [image]

Hi, Do you use Orin developer kit or your own custom board?

Hi, So you insert a USB disk to a type-A port on Orin developer kit, execute initrd to flash rootfs to the disk, and it gets stuck in middle of flashing. Is it correct?

I insert the USB to the pc. I execute initrd to flash rootfs to the disk, I use the command:sudo BOARDID=3701 BOARDSKU=0000 FAB=TS4 BOARDREV=A.0 ./tools/kernel_flash/l4t_initrd_flash.sh -c tools/kernel_flash/flash_l4t_external.xml -S 20GiB --external-device sda1 --direct sdb jetson-agx-orin-devkit external it gets stuck in middle of flashing.

Hi, Your setup looks not right. Should insert one USB disk to Orin developer kit. Please try to flash through SDKManager. USB is an option for storage in SDKManager.

We used the same connection method and command and ran it in the folder generated by SDKmanager and it has been successfully flashed into the USB.But after we successfully compiled the folder swipe ourselves, we encountered the problem in the image above. I copied the signed file which is generated by SDKmanager to my own compiled folder, so that it can be successfully flashed into the USB. How did the files in this folder get generated?
