Driver fails to start with kernels 4.8, 4.9 and kernel hangs #57

Open MrEngman opened 7 years ago

MrEngman commented 7 years ago

I am getting the following error when trying to run the driver on a Raspberry Pi B+ ARMv6 and the Pi appears to hang.

The error is identical on kernels 4.8.13, 4.9.0 and 4.9.2 other than the actual address values and the two lines

appear as one with kernel 4.8.13.

Error on Raspberry Pi kernel 4.9.2, with 4.9.0 and 4.8.13 identical.

MrEngman commented 7 years ago

Any ideas anyone? I would really like to fix this but my knowledge of C is almost none.

Can anyone suggest how I could go about debugging what the issue is?

refi64 commented 7 years ago

What happens if you remove every instance of -DRESOURCE_PRE_ALLOC from os/linux/config.mk and rebuild?

MrEngman commented 7 years ago

The driver fails to compile with a load of errors.

I see the same warnings as in my first post but then further on a number of errors shown below and the compile fails.

I got it to start with setting the kernel parameter "coherent_pool=4M". But no luck with starting an AP yet.

I have this issue too. Running a Raspberry Pi 3 B+, kernel version 4.9.73-v7+
