Hi, maybe you read the other mail about the RPi and openlabs transceiver module. at86rf233 datasheet says 7.5 Mhz is the highest clock, but since the RPi clock can run at 7.35 Mhz I expierence issues with the openlabs transceiver. Set the max spi clock to 6 Mhz solved this issue. Please update the device tree according to that value. I tested two different transceivers with the same issue at 7.35 Mhz spi clock. Thanks. - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
