[U-Boot-Users] Nothing display in terminal with uboot 1.1.3 on 8347 board!
Dear All,
After we program the HRCW and uboot.bin(1.1.3) into Flash and power on, nothing is shown in terminal, it seems that the UART doesn't initialize correctlly. Our board information is as follow: CPU:MPC8347E Memory:256 DDR 333 DIMM Flash:S29GL064MR2 8MB (8Mx8x1)
We program the HRCW into FF800000 and uboot.bin into FFF00000, and we also use Debugger check the values we programed, both Flash and Memory can be written when power on through the Debugger we find it really goes to the Address FFF00100 where the start of UBoot(start.S) to run the uboot image, but how can I trace the running process step by step? If no information display in terminal, whether it is caused by the wrong address set in configuration file or by the serial initialization?
Best Regards,
Simon

Well, then debug it...

Use your debugger.
If no information display in terminal, whether it is caused by the wrong address set in configuration file or by the serial initialization?
Or by any other error in your port. You have a debugger attached, use it. That's what it was made for.
