Flashin emmc with the sdcard image using uuu or fastboot imx8MM evk

[mariusoctavian]

I build my image following the simplest way to get imx running:
Debian build release on imx

I have an image uboot kernel and sdcard image running fine.

I can flash it on sdcard the sdcard.img and on emmc using
the sdcard u-boot ums 0 mmc 1
mount the emmc then dd the image there. So far so good.

I have to be able to flash the emmc without the sdcard help of the u-boot SPL ums mode.
I m trying to push the spl u-boot, but I am getting this error.

sudo uuu ./u-boot-spl.bin

Another method I have seen out there is making a wic
file but that wic is strong tight with yocto which I don't have.

I tried this also

sudo uuu -b sd_all ./myimage.img

I guess I had to use the 'right' uuu as old as 2 years old..

https://github.com/TechNexion/imx-mfgtools-tn

Juts build it and replaced the stock one.

Then I use it as.

sudo ./uuu -b emmc_all ./uboots/boot.bin  image_from_sd.img

# the boot.bin was fabricated frmo the image_from_sd.img dding first 8 k

I get a message at end, image to big to fit in partition, but exploring it afterwards looks okay.
