Dear Community
I am trying to use all pins of the External Interface Module of iMX7d as GPIO. I have successfully altered the device tree and the pins are properly muxed as GPIOs expect 3 pins.
Those 3 pins are
1. SODIMM_111 - EPDC_D00
2. SODIMM_113 - EPDC_D01
3. SODIMM_115 - EPDC_D02
In GPIO tool I can see that these pins are muxed as 1 SODIMM_111 - EPDC_D00 muxed as weim.AD0 2.SODIMM_113 - EPDC_D01muxed as weim.AD1 3.SODIMM_115 - EPDC_D02 muxed as weim.AD2
and all other pins are properly muxed as GPIO and working as expected. I am not able to use these three pins as GPIOs from my code(libsoc). I am attaching my device tree alteration patch file and the kernel version I am using is
Linux colibri-imx7-emmc 4.9.166-00001-g6bd85ffba9f2. Please find the boot log file
Any help or suggestion will be appreciated.
Thanks for your time.
