and thats what I got:
[ 6.182903] pxa2xx-spi 80860F0E:00: bus_num = -1 [ 6.182909] pxa2xx-spi 80860F0E:00: num_chipselect = 2 [ 6.182928] pxa2xx-spi 80860F0E:00: IRQ 194 [ 6.183049] pxa2xx-spi 80860F0E:00: no DMA channels available, using PIO [ 6.183111] pxa2xx-spi 80860F0E:00: registered master spi32766 (dynamic) [ 6.192761] spi spi-WM510205:00: 8333333 Hz actual, PIO .... the rest of the dmesg is currently the same....
Q: this thread is about the patch for the pxa2xx-spi where the num_chipselect was raised by one to so that the slave connects here at all. otherwise the cs1 >= max will be hit. Do you think the bus_number is ok ? And shouldn't it be set the cs1=0 and num_chipselect=1 ??
What is with the bus_num ? where can I find the correct one ? I have no working example, is it possible to find the right settings only via a windows installation??
