GPIO for at24lc32

[Jeff]

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

Nevermind I figure it out.

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,

Neeraj
