Hi everyone, I am trying to compile uboot for rockpi 4a and I have the following error:

./build/mk-uboot.sh rockpi4a

I have another rock pi 4b and I got it normally.. :confused: :thinking:

I believe this is not the right u-boot branch or commit, which branch are you using?

3

I get the same error, using the stable-4.4-rockpi4 branch as per the documentation

Any ideas?

And the per the documentation linked above, the branch rk3399-pie-gms-express-baseline gives the following error:
CC common/s_record.o

I got the same error When I try to reproduce the problem and I will get the resolution for you sooner.

modify line 363 in the file uboot/Makefile, delete the keyword “-Werror”, then try this command “./build/mk-uboot.sh rk3399-rock-pi-4a”

Following the above advice, I get the following:

Any ideas? Why is this such a painful process?
