Hi,
I'm trying to get a RME HDSPe MADI card to run in an ARM box with Linux
4.1.6. I configured the (vendor specific TI) kernel to support the card (via
hdspm) compiled into the kernel (not as loadable module).
The MADI card is detected as a PCI device and the ALSA driver is loaded.
Unfortunately playout does NOT work: aplay is reporting an error:
ALSA lib pcm_mmap.c:374:(snd_pcm_mmap) mmap failed: No such device or
address
Does anybody have an idea what might be the reason?
I tested the card on Linux x64 and it worked flawlessly.
Below is info about the system, aplay output and an strace of the relevant
part.
Thanks in advance
Axel
