I ran it but grep APPSIZE does not give me anything. I do not know what is the problem. it seems like the tool is not generating the flash.xml.tmp file in the /signed directory and I’m not sure if it is because of the APP partition size. Is the above file * flash_l4t_t186_rootfs_ab.xml* the correct one to edit for the APPSIZE?
These are all the files under the /bootloader/t186ref/cfg
