Hi all!

 

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.

 

Best regards,

Andrey
