GPIO configurations

Wed Jun 13, 2018 10:58 pm

Hi,

I am new to SAMA5D3 programming and facing some issues while trying to change the GPIO configurations for a custom board.
My register settings are not changing/sticking so I also tried clearing WPEN bit as well but it causes to break into BootROM.

Please let me know if there is sample code to follow ?

Thanks
Nisha

And what else?
Usually this turns out to mean that the person is not an experienced programmer in any discipline whatsoever.
That's not necessarily a bad thing, but if you insist on concealing it, then you're a phony.

How do you know that this "custom board" is fully functional?
What software environment are you using: baremetal, Linux, some RTOS?

What does this mean?
What is "BootROM"?
The processor/board was reset?
