U-Boot : 'make' problem

Hi Max,

Ok. When building u-boot this is the "PK1C20_config" -- so this is correct.

> I am using the MS hyperterminal to get a terminal,

Ok ... make sure you're using the connector at the rear of the board (next

to the Ethernet RJ-45).

> it expects to get a connection through the UART, is it right

Yes, you should see the u-boot banner, some SYSID info, then get the u-boot

command prompt ("==>").

> I suppose I don't need any uCLinux

Correct. uClinux is not needed ... in fact, u-boot is normally used to boot

uClinux (or other OS).

I don't know the internals of nios2-download -- but probably because an srec

download is much easier to code ;-)

Yes ... but I don't think many developers are using it.

A few things to check: Confirm that your Nios-II design and the

include/configs/PK1C20.h file match up WRT reset address, exception

address, etc. Also, did you build the example & program it to the EPCS or

download it via JTAG? Or are you using the factory configuration?
