[U-Boot-Users] Porting UBoot without UART

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.
