Re: [U-Boot-Users] Pointer to similar board?

Oops, you caught me 8) Its the CS8900, not built in.
When I compile the kernel as a zImage (changing mach_types entry for SMDK2410 to my unit's ID) it has no problem talking to the serial port at ttySAC0. Using the SMDK2410 for u-boot I get no serial port activity at all, not even the LED that indicates the target's serial ports are in use.
I changed the boot delay in configs/smdk2410.h to -1 to make sure I could get the right port (swapping the cable around in case it wasn't uart 0 being used. I also tried 60 delay. Still nothing.
You should see some U-Boot boot messegas reagardles what boot delay you configured. Maybe your clock configuration is wrong (wrong baudrate). Or the SMDK2410 uses another serial interface as console as your board? Or the SDRAM configuration is not suitable for your board. Or, ... there are many things that could go wrong. Unfortunately thers is no quick way to port U-Boot to a new hardware (see the "U-Boot Porting Guide" section in the README in the U-Boot source tree: http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=README;h=5cbe7c1... :-)
Perhaps I'm expecting the wrong result from u-boot? Is the SMDK2410 default config supposed to give a prompt at all or go straight to DHCP et. al?
It was some time ago, I last used the SMDK2410. But I'm pretty sure, that it prints some boot messages. You should see this messages regardles if you boot from flash, ethernet, or whatever.
Please keep the list on cc.

I am not really sure if the smdk2410 port is working at all at the moment.

I can only speak for the s3c2400 (trab, and most probably also smdk2400), which were broken by this commit:

Changed API name to coloured_led.h Removed code using deprecated ifdef CONFIG_BOOTBINFUNC Tidied other cpu/arm920t/start.S code

That was it! Went back to 1.2.0, flashed my NOR and upon reboot got the uboot menu.
Thanks very much! Being new to this stuff I always assume its me doing something wrong and spend a few days wracking my brain and overheating the google servers before actually asking a question. I learn a lot but its hard on the hairline 8)
