u-boot imx8mm does not boot from sdcard neither from e-mmc

[mariusoctavian]

I have imx8mm evk

I am using this u-boot.

git clone https://github.com/nxp-imx/uboot-imx

I installed aarch64-linux-gnu- /usr/bin (ubuntu 22.04),
and I also have the aarch64--glibc--stable-2022.08-1 (I tried both compilers)

I am building like this.

COMPILER=aarch64-linux-gnu-  # from apt
##COMPILER=aarch64-linux-

export PATH=/path/to/tc/bin:$PATH

ARCH=arm CROSS_COMPILE=$COMPILER make imx8mm_evk_defconfig
ARCH=arm CROSS_COMPILE=COMPILER make clean
ARCH=arm CROSS_COMPILE=COMPILER make

after building I have these files

find -name '*.bin' -o -name '*.img'
./u-boot-dtb.img
./u-boot-nodtb.bin
./spl/u-boot-spl-nodtb.bin
./spl/u-boot-spl.bin
./tools/binman/test/descriptor.bin
./u-boot-dtb.bin
./u-boot.img
./u-boot.bin

I tried to dd the u-boot and/or spl as all kinds of combinations I've could find in scripts.

sudo dd if=./u-boot-*.bin<img> of=/dev/mmcblk0 bs=1k seek=XX=33/69
 

What is the right dd command and what u-boot files and what seek (ofsets) are correct ones for IMX8MM
sdcard and emmc?

I also tried all these

$ sudo dd if=<U-Boot image> of=/dev/sdx bs=1k seek=<offset> conv=fsync
Where offset is:
• 1 - for i.MX 6 or i.MX 7
• 33 - for i.MX 8QuadMax A0, i.MX 8QuadXPlus A0, and i.MX 8M Quad, and i.MX 8M Mini
• 32 - for i.MX 8QuadXPlus B0, i.MX 8QuadMax B0, i.MX 8DualX, i.MX 8DXL, i.MX 8M Nano, i.MX 8M Plus,
i.MX 8ULP, and i.MX 9

Thank you

Hi @mariusoctavian 

I'd suggest you refer to the <4.5.12 How to build U-Boot and Kernel in standalone environment> and <4.5.13 How to build imx-boot image by using imx-mkimage> of i.MX Linux User's Guide (nxp.com)

Best regards

Harvey

Thank you,

I skipped the yocto thing. I will try with yocto, as looks like there is no escape from it.
I will reply as soon I get some positive results.

lol, i start yocto build yesterday, still building after 7 hours, octo core i7 2.7ghz ram 32gb

make imx8mm_evk_defconfig
make

I found that I need the imx-atf as well.
I cloned this:
https://github.com/nxp-imx/imx-atf
I Have gcc/c++ 9..to 11
git checkout imx_4.9.123_imx8mm_ga
ARCH=arm64 CROSS_COMPILE=aarch64-linux- && make PLAT=imx8mm CFG_ARM64_core=y

I tried all of them and I cannot pass

gcc: error: unrecognized command line option ‘-mstrict-align’; did you mean ‘-Wstrict-aliasing’?
gcc: error: unrecognized command line option ‘-mfix-cortex-a53-835769’

I tried to comment those then The errors goes deeper.

cc1: error: bad value (‘armv8-a’) for ‘-march=’ switch


Any help would be appreciated
