[Linux-zigbee-devel] GPIO error with PXA270
Hello, I'm trying to use 6lowpan on imote2 platform but with kernel 3.3-rc5 (latest git linux-zigbee devel ) I have this error at bootup: ... [0.265882] gpiochip_add: registered GPIOs 0 to 31 on device: gpio-0 [0.269766] gpiochip_add: registered GPIOs 32 to 63 on device: gpio-1 [0.273585] gpiochip_add: registered GPIOs 64 to 95 on device: gpio-2 [0.278527] gpiochip_add: registered GPIOs 96 to 120 on device: gpio-3 [0.312939] __mfp_validate: GPIO91 is invalid pin [0.313038] __mfp_validate: GPIO103 is invalid pin [0.313072] __mfp_validate: GPIO104 is invalid pin [0.313107] __mfp_validate: GPIO105 is invalid pin [0.313141] __mfp_validate: GPIO102 is invalid pin [0.313176] __mfp_validate: GPIO1 is invalid pin ... Also, before this I add this 2 line in pxa27x.c file: INIT_CLKREG(&clk_dummy, "pxa-gpio", NULL), INIT_CLKREG(&clk_dummy, "pxa27x-rtc", NULL), otherwise a -22 error result in gpio probing phase So, cc2420 driver cannot be loaded (neither that use gpio, including leds) is there any patch ? thank you very much Andrea -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
