We are working on a new design using the OMAP3525, and are just gettiung started with the S/W bring up. We have been able to use the ROM bootloader via serial port, and have a small piece of code running. However, our code that toggles GPIO135 works well. If we change this to toggle GPIO80 it does not work. GPIO80 is floating. If we run the exact same code on the Beagle Board, GPIO80 toggle just as it should. Now I know the BEagle Board is using the OMAP3530. Does anyoine know of any possible fifferences between the OMAP3530 and the OMAP3525 that may effect the operation of GPIO80? We have checked our hardware, and there is nothing external to the chip driving the line. We have also tried on multiple boards, so it is not a faulty solder joint.
Any advice, tips, clues or hints are appriciated.
