if I load sampler/ panelui before loading hm2_etho I get an error.
If I load them before, it at least loads with no error - though I haven't tested everything.
The pertinent errors are:
rtapi_shmem_new failed due to shmget(key=0x48534130): Permission denied
hal_stream_attach: Permission denied
shmctl(21004310, IPC_STAT, ...): Permission denied
hal_stream_detach: rtapi_shmem_delete: failed with code -22
I can reproduce this error in the sample config: sim/axis/panelui_demo
by adding two lines (before loadrt sampler) to load my etho card:
loadrt hm2_eth board_ip=192.168.1.121
My guess is shared memory key conflict?
I couldn't find where hostmot2 etho uses a shared memory key.
