sdpv write -f flash.bin -skipspl

Hello, I am using uuu to write to eMMC on imx8MM evk.

It works but I haven't understood what the -skipspl does when I run the command

uuu -b emmc flash.bin

it executes sdpv write -f flash.bin -skipspl.

my flash.bin file is an aggreagate of spl and u-boot, together with all the other ATF, DDR4 training and IVT .

Why the uuu emmc script adds this -skipspl that sounds like "skip programming spl" ? I couldn't find a reference about this SDPV and this option .

Thank you

Hi Antonio

seems skipspl "skips some data when using spl" while searching uboot position

it is used by SDPV which is upgrade version of SDPU :

Support -skipspl option at sdp protocol (a4bbea24) · Commits · Librem5 / mfgtools · GitLab

Best regards
