Hi all,

I have a at91sam9g45ek-es based board.
I have already Linux 2.36 running smoothly with plenty of peripherals.

Unfortunately I can't make an external UART (ebi_cs 1 and 2) and external SRAM work

I'm willing to pay for that. I think it is an easy tasks for the gurus, just point me out here to make changes/checks.

Please contact me with you are a guru. edgard dot lima at gmail dot com

Hi there

Before you concern yourself with Linux device drivers, you should have tested out these devices in U-Boot. U-Boot does not activate memory management (i.e. virtual memory), so everything should reside and be accessible at their physical memory address. The memory display and memory modify commands will quickly indicate how broken the interfaces are.

Regards
