I want to use the iMX7 in my System without any physically connected display running WEC2013. I started with the schematics of the IRIS V1.1 board and the iMX7D maunual and tried to figured out, which gpios were available.
Due to a bug of the SPI driver I found out earlier and no chance that this bug get fixed I was told by Toradex to use SODIMM 133 as a manual nCS. And I have to use tis pin exclusively, so no other usage of this GPIO 2 module is allowed. ==> GPIO2 is only godd for that nCS.
This gives the list of remaining GPIOs:
And, if using any of that free GPIOs, please note, that toggling a pin within an ISR also means, that that the whole GPIO bank isn’t available for other threads!!
Is the above list correct, or is some of the GPIO-banks, or ports still used by WEC2013?
Thanks a lot for helping.
With best regards
