layer23 on GTA02 AP and ARM unaligned memory access

Hi list, I'm running layer23 apps on the Application Processor of the OpenMoko GTA02, which is also an ARM. I noticed that some parts of code try to access words in memory which are not naturally aligned. [ The first symptom was "Err from socket: Bad address" given by osmocon. This is because a bogus length header read from the L2 unix socket was overflowing a static 4K buffer. The bogus length was due to an unaligned uint16_t write in osmo_send_l1() -- for an L1CTL_DATA_REQ I think. ] The easy and inefficient workaround for this is to ask the kernel[1] to fix up these accesses: echo 3 > /proc/cpu/alignment Cheers, Alex [1] http://lxr.linux.no/#linux+v3.7.1/Documentation/arm/mem_alignment
