Hi,
I am trying to get an MRF24J40MA up and running on a Raspberry Pi.
So far, I have a 3.6 kernel and modules compiled with the latest linux-zigbee
changes (including the mrf24jm40 driver) backported to 3.6. CONFIG_SPI is set
and offers the devices /dev/spidev0.0 and /dev/spidev0.1. I have tested SPI to
be working with spidev_test from the kernel documentation. Modprobing mrf24j40
succeeds, but does not show anything in /var/log/messages or dmesg.
In some email back on the list when I wasn't subscribed Alan and Randy wrote:

Could the missing irq in the Pi's spi_board_info be a problem?
static struct spi_board_info bcm2708_spi_devices[] = {
{
.modalias = "spidev",
.max_speed_hz = 500000,
.bus_num = 0,
.chip_select = 0,
.mode = SPI_MODE_0,
}, {
.modalias = "spidev",
.max_speed_hz = 500000,
.bus_num = 0,
.chip_select = 1,
.mode = SPI_MODE_0,
}
};
Any pointers are appreciated,
Markus
