Hello all, I've been using both fixed pinmux and pinmux helper entries in my device tree overlay successfully in Wheezy. However, while moving forward into Jessie I've discovered that the pinmux helper only generates the 'state' fd in /sys/devices/platform/ocp/ocp\:P8_37_pinmux/state for non-lcd/hdmi pins. I observed this with cape-universala, cape-univ-hdmi, and my own cape so I looked for disparities between kernels.
It seems Robert's 4.4.20-bone-rt kernel works just fine for all pins including hdmi pins. However the ti kernel that ships with the stable public images (2016-08-28, 2016-5-13) is missing pinmux functionality for all LCD/hdmi pins. I have checked with the following kernels: not working: 4.4.9-ti-r25 4.4.20-ti-r43 4.7.3-bone2 working: 4.4.20-bone-rt-r13 Furthermore, normal fixed pinmux settings in overlay's target = <&am33xx_pinmux> section, (like BB-UART5 for exmaple) do not seem to have an effect in these ti kernels either. So right now I can't access anything between P8_27 and P8_46 without installing a new kernel. Is there a workaround for this? I would like everything to work on the kernel in regular releases. Thank you for any input. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
