Subject: [U-Boot-Users] Porting UBoot without UART
Date: Tue, 22 Feb 2005 11:21:01 -0800	[thread overview]
Message-ID: <c3d0340b0502221121c489be4@mail.gmail.com> (raw)

Hi,

We're using some emulation box to develop our SoC. Somehow the UART
will the last component available for firmware development. Without
UART, it's very hard to debug UBoot. Can we "easily" drive a car
without eyes?

But it's not impossible to do that. My first thought about porting
UBoot under this circumstance is to disable the serial driver in UBoot
and to redirect all printf to a fixed memory area, just as what a
circular log buffer does. I'm wondering how much workload this will
be. Is this kind of mechasim already existent in UBoot?

Thank you for your comments.
-Shawn.
