Felix, The GPIOs in trunk are working correctly - they behave like the Original Firmware. When the Radio 0 (2.4GHz) is enabled the GPIOs for the LNA0 and LNA1 are set to HIGH and when the driver for the Radio 0 is disabled the GPIO's are set to LOW.
The command: "cat /sys/kernel/debug/gpio" was very useful. For Radio1 (5 GHz) what is the way to test if the LNAs for that radio are enabled/disabled?? Luis On Wed, Feb 12, 2014 at 10:13 PM, Luis E.
