- Subject: [ECOS] AT91EB40 RedBoot install problems - solution!
I had the same problems reported on the list when trying to install
RedBoot on my AT91EB40 board - I'd follow the instructions to the letter
in the RedBoot manual, but after suspending gdb with ctl-Z, minicom
wouldn't communicate with the board at all.
Then I lucked out - I started gdb (for the 1000th time!), went through
the instructions up to the "lo" command, and then happened to start to
search for stuff on the mailing list pertaining to this problem. When I
got back to gdb after 40 minutes or so, I issued the "c" command, and
sure enough, RedBoot started, as evidenced by the fact that all 3 LEDs
lit up. Suspending gdb and starting minicom, I was finally able to
communicate fine with RedBoot.
So it may all be a matter of timing - after the load command finishes,
the board still isn't immediately ready to have the RedBoot RAM program
started. I don't know how long is long enough to wait before issuing the
continue command, but if the 3 LEDs don't light up, it wasn't long enough...
