I need to change GPIO default values for BF537 processor as it starting up.
As soon as I underatand there are 2 options:
- code in boot ROM;
- code in bootloader (initcode.c in case of u-boot).
Is there any sample (asm or c) how can I change GPIO values? Specifically I need to change PF6 value.
I'm a newbie, so any help will be appreciated.
