(i posted something similar to this on the SF forum before i
realized there was a real mailing list. oops.)
before i commit myself to reflashing with u-boot, i'd like to know
if it's possible to just load it into RAM and use the current
bootloader to jump to it, just to see the menu come up, nothing more.
working with an 8xx board, 850DE-based, and as a test, i did a
configure with RPXlite_config (even though, technically, it's not
exactly an RPXlite but close). generated u-boot.bin and used embedded
planet's planet core (PC) bootloader to download it into RAM. at this
point, am i allowed to just use PC to
> g <download address> ??
we could do that with PC -- compile a new version, download it to
RAM and jump to it, just to see that it seemed to function at the
thoughts? i've tried it, and every time i use PC to transfer
control, i get nothing -- immediate hang. maybe a serial comms
problem? who knows?
