[ECOS] Re: booting from ROM
Tue Oct 16 09:59:00 GMT 2001
I posted a similar question a few weeks ago. I believe the problem is NOT
in the linker scripts. When I tried to run the "hello world"
program from ROM (that worked correctly from RAM via gdb),
I could not get the UARTS to work correctly. I even changed
printf to diag_printf, but that did not help. I tried
just reading/writing to memory, and that works great, so
large parts of the startup is working correctly, only
the serial I/O is not. I have a custom board that is VERY
similar to the brutus/assabet ports.
If anybody has actually tested the "hello world" program
to run out of ROM, I sure would like to know what you configured in
the .ecc file and any other files to get it to work.

I found the following message about running "hello
world" from ROM.
Can anybody tell me what is MLT? Where can I find
more information? Why jflsh hello.bin to Assabet
doesn't work. Thank you for your help.
