Kernel: stable-5.10.y
HW: chipset APQ8064, Nexus 7 2013 (codename flo or deb)
Problem first occured when I was porting Nexus from 4.19 to 5.4 LTS.
Hello,
after reverting this particular commit (
498b98e939007f8bb65094dfa229e84b6bf30e62 ), I'm able do
echo 'start' >

with current stable-5.4.y - stable-5.10.y (cannot test later since it
crashes without saving pstore dmesg):

[ 50.977225] remoteproc remoteproc0: Boot failed: -22
These logs are from 5.10 LTS. Firmware files are untouched between
kernel versions.
I'll be very grateful for any tips or patches to test (best against
5.10, I haven't been able to fix and run later versions yet)
Best regards

I believe that the APQ8064 boards fell out of the various automation
setups and we lost track of the status. Hopefully we can resurrect
e.g. the ifc6410 to catch these kinds of regressions.

Seems like the reasons for this would be that the ELF header and
signature segment are stacked differently from the firmware I looked
at when I came up with that patch.
Can you please share the output of "readelf -a wcnss.mdt"?
