Hello,
I have a rev B BeagleBone Black which I have been using for over a year as a development platform for a pseudo-clone board we are developing. We are using QNX as our OS.
Lately I have been tinkering with U-Boot to learn how the boot process works and configure our board properly. I cloned the U-boot git repository and built the 2015.10-rc2 version. The board boots fine and now the MPU frequency gets configured at 1GHz, but the thing is that the gpio console command doesn't seem to work anymore.
Previously I used the 2013.04 version of U-Boot and could toggle leds using the gpio comand (i.e. "gpio toggle 54" ), but now the same command just returns an error message "Command 'gpio' failed: Error -22".
Is there anything I've missed to make this command work properly? For building u-boot I used the am335x_boneblack_defconfig configuration.
Regards,
Francisco
