Hi,
this is due to fact that pi433_write returns 0 on successful copy while
it should return 'copied' value. So it is a bug :)
'0' means nothing was copied so userpsace calls pi433_write again and
again, data is put to fifo and when it is full it goes to abort and
returns -EAGAIN and logs message write to fifo failed: 0x0
Additionally set_devaiation is also failing due to unset tx_cfg values:
[ 64.231216] pi433 spi0.0: set_deviation: illegal input param
Ideally would be to have 'dafault' rx/tx config set in the driver.
Regards,
Marcin
