I see that if I edit */boot/uEnv.txt* and comment out: #enable_uboot_cape_universal=1 I can then access all sorts of gpio pins. But now I can't run config-pin on them since there is no pinmux entry in /sys/devices/platform/ocp.
Is there a way to free up a few gpio pins to drive the LCD and keep the rest pinmux-able? --Mark On Wednesday, November 29, 2017 at 10:10:36 AM UTC-5, Mark A.
