imx8mm UUU qspi partition

[vignesh-baskaran]

Hi,

We were exploring QSPI for booting and load images via UUU.

1) We trying to load the whole wic image created by yocto into QSPI.

$ sudo uuu -b qspi core-image-minimal-imx8mm-lpddr4-evk-20230519111834.rootfs.wic

uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.21-3-gcbff795

Success 0    Failure 0                                                                                                                                       
                                                                                                                                                              
                                                                                                                                                              
1:8      2/ 3 [==>               9%                  ] SDPV: write -f core-image-minimal-imx8mm-lpddr4-evk-20230519111834.rootfs.wic -skipspl -skipfhdr   

 It goes upto 10% and then fails.

We seen for emmc, We searching to do same for QSPI.

Decompress rootfs image and burn into emmc (since 1.1.87)
uuu -b emmc_all bootloader rootfs.sdcard.bz2/*

2) We also trying to do partition the qspi via UUU. and load each image(u-boot ,kernel , dtb and FS) as separate images.

is there way to do it? Please let us know.

Can you try to download only the uboot to the QSPI?
