Subject: [U-Boot] ASM code for UART initialization
Date: Thu, 06 Jun 2013 11:27:48 +0200	[thread overview]
Message-ID: <51B05614.8070505@googlemail.com> (raw)

Hi,

could someone support me with developing ASM code for initializing UART
interface on OMAP4460 to send some bytes over the wire at a very early
stage of booting x-loader? The code needs to be executed in start.S.

Is it possible to use existing C code and use the generated assembly
from gcc as the actual code or does it need major modifications to be
executed in start.S?

Thanks in advance.

Regards,
Andr?
