Getting write protected issue while flashing using UUU with command sudo uuu -b sd imx-boot


Kindly suggest on this. Thank you in advance.

Hi Sulaiman

 

from log: "The SD card is locked"  one can check lock switch on SD card.

In general recommended to try brand new SD/eMMC device and use latest

BSP and uuu tool :   https://github.com/NXPmicro/mfgtools/releases/tag/uuu_1.4.139
