Reading file would overwrite reserved memory. Failed to load 'hello_world.bin - imx7d-pico - Uboot 2022.04

Hi,

I had this issue last year and I solved it via device tree. However, I used
Yocto hardknott and uboot 2021.04 and Ubuntu 20.04. Now I use Yocto
kirkstone and uboot 2022.04 and Ubuntu 22.04


I've been trying to resolve this issue for seven days now. I've already
made several changes to the uboot and yocto/device tree configurations
without success.

Every help is welcome

Note I tried:

If you add '#define LOG_DEBUG' to the top of lmb.c you should see some
debugging about the reserved memory.

Thanks
ButI've already done that and it didn't help at all. I also have the
results of bdinfo command and cat /proc/iomem in it has not helped me

I'm sorry, but I think you will need to debug this, unless someone
else has a bright idea.

Thererror is in fs_read_lmb_check() so something must be wrong in what
you think should happen in lmb_alloc_addr(), I suspect.

This is presumably caused by lmb (logical memory blocks). You could
dump out the lmb list with lmb_dump_all() before doing the load. The
'bdinfo' command does this, but it looks like you can add '#define
LOG_DEBUG' at the top of lmb.c and it will do this before the load.

Hi,

I had this issue last year and I solved it via device tree. However, I 
used Yocto hardknott and uboot 2021.04 and Ubuntu 20.04. Now I use Yocto 
kirkstone and uboot 2022.04 and Ubuntu 22.04


I've been trying to resolve this issue for seven days now. I've already 
made several changes to the uboot and yocto/device tree configurations 
without success.

Every help is welcome
