Hi,This is great news! I was half the way of working on the same
Toradex is currently working on integrating the new NXP release
'L5.4.24_2.1.0'. For this we created a new kernel branch '5.4-
based on NXP's kernel 'imx_5.4.24_2.1.0'.
We already merged patches from stable linux 5.4.47 into '5.4-
but now since you have the merge done - I can take your version
@Otavio: I sincerely ask you if you could place the branch '5.4-I'll grab this one to test on i.MX8M Mini EVK now and try it out.
imx' that resides currently in my private github account:
meta-freescale, and saw couple of issue with imx8mmevk machine:
1. imx-gpu-sdk recipe fails to build, as it requires the header which
is most probably missing in the kernel:
make: *** No rule to make target'/development/projects/master/build-output/work/cortexa53-crypto-
with BSP 'L5.4.24_2.1.0'.
OE-core updated glibc which is the provider of 'sys_errlist.h' so maybe
that is the reason for build failure?
Correct! My bad: I did a pull of OE-Core and then your Kernel branch,
which I should not have been doing in the first place. This issue is
not from Kernel, it is a pure glibc one. Thanks for pointing it out!
Thanks for pointing this out, I could reproduce the issue and checked.

There were still two commits missing. One revert that we believe is not
applicable to downstream fec_main.c
This one also solved the issue. The other IPU commit was also missing.
Now it works on our side. Can you confirm?
Yeap, Kernel build off commit 1e10771673463a332a7e477fcba0b9488ec5362b
boots fine on i.MX8M Mini EVK. I haven't verified whether graphics and
multimedia are OK, but in general at this state this merge is
I believe you can make a PR in https://github.com/Freescale/linux-fslc
for Otavio to have a look at it.
With that said:

We were building binutils-2.34 so didn't notice this issue. I've
