Ram size would not be a typical concern in a PC target (I think). We
are running with 256M of RAM, and probably using less that 64M of

point me in the correct direction.
You need to juggle the base address for RAM startup in the mlt
files. You also need to create a redboot_GRUB.ecm file -- copy the
FLOPPY one and edit it. In theory Redboot should then just work --
although I cannot guarantee it, you'll just have to try it and see.
Yes, I can load an application with GRUB off the network, but it is
not as convenient as with GDB. (Need to set up TFTP/FTP server? GRUB
documentation was not clear on what (ND) was supported when I scanned
it). But debugging serial would be a real pain.
The only real pain in debugging via serial is downloading the
executable. But if you have downloaded via the network, then the
actual interactive debugging over the serial line consists of
relatively light traffic. And you can always put it up to 115200 baud.
