Hi All,

When i tried to access the GPIO module registers of the DM8148 for example the OUTDATA register or the OUTPUTENABLE register, my application crashes.

Anyone meet this problem or has the solution, help

    Hi,

    How are you trying to access these registers? From u-boot? Linux kernel? Linux user-space? or BIOS?

    How is it crashing? A data abort might indicate that the module is in reset.

    Make sure the GPIO subsystem is powered and out of reset i.e enabled through the PRCM.
