UUU tool not working in closed i.MX 6UL

Contributor III


I'm experiencing issues with UUU tool in Ubuntu 18.04 as it's not working (it waits indefinitely) on closed i.MX 6UL EVK.


The script we're using is given below:

uuu_version 1.2.39

SDP: boot -f uboot_signed.imx

FB: ucmd setenv fastboot_dev mmc
FB: ucmd setenv mmcdev 1
FB: ucmd mmc dev 1
FB: flash bootloader uboot_signed.imx
FB: Done

The same script is working fine (flashed bootloader in SD Card) in a open, secure board and uboot_signed.imx is also manually verified to be working.

The fastboot parameters are as follows:

Detailed log is given below to aid in your diagnostics:
$uuu -v ./signed_write_boot_sd.lst
