Flash programmer via ethernet

Thanks Scott,

I found my main problem was those env variables. The 1S10_ES kit board (DK1S10?) must be very close to the PK1C20 configuration since most things are working. I have tested downloading images to this board using srec over serial, binary over serial and tftp (after installing the free solarwinds tftp server). I burned u-boot into the board using u-boot itself as in the USING directions.

u-boot is pretty slick. It give you most of the features you would want from a boot monitor program. I have not been able to download and run the supplied hello world example, though. I used the "loads" and it did load, but a "go 800000" just seems to reboot u-boot. The example output is supposed to appear in the u-boot console window isnt it (not the jtag uart or debug port) ?

It would be nice to have the following:

A way to connect to the u-boot console over ethernet. As you mentioned, u-boot downloads are "pull" model, but if I could use telnet or ssh to get to the console, it would be exactly what I am looking for.

A command that tells you where u-boot is executing from, and what system resources it is using. This is not very clear.

A little more description for the configuration options. The custom board I need to port to has a different memory map and no SDRAM bank. It is not clear if I simply remove CFG options, and what option controls where u-boot relocates to.
