Hi,

I'm trying to run 2019.07 u-boot on raspberrypi cm3 module but I got
no feedback on console. When used 2018.01 it boots fine. Probably I
need to do git bisect but maybe someone have some idea or experience
what can cause that. Thanks.

BR,

marek

I give a try 2020.01 and I got only this:
U-Boot 2020.01 (May 06 2020 - 20:09:45 +0000)

DRAM:  948 MiB
RPI Compute Module 3 (0xa020a0)

I'll try to debug it and let you know.

marek

Debug messages shows this:
https://pastebin.com/2SwNzrb1

I tried to debug but I have no clue what is going one there.

Also u-boot 2019.07 is not working at all on cm3 due to this commit
(after bisect when reverted u-boot start working again):
143256b353c4d2ad1cf5e5e63b38410188b35e49 - fdt: update bcm283x device
tree sources to Linux 5.1-rc6 state

Any ideas hint how to resolve this issue? Thanks.

Can you try to cherry-pick the following two patches to your tree:
5051377a0b ("arm: dts: bcm283x: Rename U-Boot file")
89e47e8eb6 ("fdt: fix bcm283x dm-pre-reloc definitions")

But those are present in 2020.01 and this version at least print
something to console but stuck somewhere (pls see pastebin log with
debug enabled)
I prefer to run 2020.01 ;). Thanks.

Any other stuff I can try to make it working in 2020.01? Could that be
firmware issue somehow? Thanks.

Sorry I didn't realized that your first try was with 2020.01.
I just confirmed that it acutually does not boot. As a shortcut, do you know
which is the last working version of U-Boot?

v2019.07 with reverted  commit :
143256b353c4d2ad1cf5e5e63b38410188b35e49 - fdt: update bcm283x device
tree sources to Linux 5.1-rc6 state
work fine. Without revert it shows anything on console. So something
between 2019.07..2020.01 mus fix it partially ;)

I just tired v2020.04 and it works for me. Would you mind testing that on your end?

Do you have a hard dependency on v2020.01?

OK I'll give a try and try to bisect between 2020.01 and 2020.04. I
have dependency on 2020.01 as I integrate mender

The result for me is:
7099d71d87 ("common: Drop mdm_init()")

which kind of makes no sense. Can you retry, I think I made a mistake somewhere
