2010-11-04 06:38:20     2010R1-RC2 serial / console problems

I am using 2010R1-RC2 for the DNP/5370 board. For this, I re-used the board support file from a 2009-R1.1-RC4 installation without changes.

The first problem is that there is no console. I don't see the kernel booting. With a soft reset and post-mortem kernel debugging using u-boot I see the kernel boot messages:

The kernel bootargs are the same as used with the 2009R1.1-RC4 kernel. The 2009 kernel boots with a working console and I can log into that system.

You should use 2010R1-RC2 uboot release as well other than

U-Boot 2010.09 (ADI-2011R1-pre) (Nov 03 2010 - 18:11:38)

So does the 2010R1-RC4 toolchain.

Ok, the toolchain was 2010R1-RC4, but I am now using the u-Boot version you requested.

I found that the board config changed for the STAMP board from 2009R1.1 to 2010R1 release and I copied the serial settings from there. Now I am back with a system where I can log in.

Now I'm at the same state with the new kernel as I was with the 2009 one. No ethernet, but the PHY is detected correctly without my modification of bfin_mac.c. I'll now dig into that issue again and open a new thread if I'm unsuccessful.

Thanks again for your responses.
