        Hello,

        It’s my understanding there is a dedicated gpio for disabling the write protect on the at24lc32 eeprom inside the package.  I cannot find the actual gpio number or mapping from the sitara anywhere.  I need to be able to write to that eeprom from linux.  I cannot use uboot as we have a custom bootloader.

         

        Thanks,

         

        Jeff

            For completeness of this post, EEPROM_WP(M2) can be used to disable write protect for the internal EEPROM. This pin has an internal pull-up.

            Best,
