Hi everybody !
I finally managed to have a good footprint of ecos, the size I want it
to be actually, and I compiled both hello & twothreads code samples
from the ecos' example directory.
But, i have a small problem when I try to upload the code to my board
within gdb, the console gives me that:
Loading section .rom_vectors, size 0x40 lma 0x0
DOWNLOAD FAILED: Memory access error while loading section .rom_vectors
I haven't been able so far to get any code on the board :(
Does anyone have an idea of what I could have done wrong ?
For information, i used the Olimex LPC2106 Eval Board hardware config
with a "kernel" template and the build went pretty fine from start to
finish. After that I just compiled the twothreads.c example file using
my target file.
Thank you in advance !

Are you trying to load this into FLASH? I assume so, since the LPC
family is designed to run code directly from FLASH.
gdb is not directly capable of that. You need a JTAG programmer.

Yes i'm trying to load the code into FLASH. I use OpenOCD for the GDB
Remote Server, with an Olimex USB-JTAG-KEY.
In gdb I can see the code presently running in flash, can see the
registers as well, but i can't manage to use the "download" feature
without having the error I described above.

I've never used OpenOCD, but in my experience with JTAG devices, there
is a separate program used to download code into flash.

Well Olimex advises to use OpenOCD for their JTAG device so :(

I did a little googling. Use telnet to the OpenOCD daemon CLI.

And a good ol' "help" inside that telnet console solves 99% of the
problems :)

There is an example in the configuration example for OpenOCD. To debug new firmware:
1. Download firmware into flash using the OCD configuration or telnet interface
2. using insight or eclipse attach to the dbg server and start eclipse session
there is a slide presentation in the Yargto tools for doing this.

Hi!
Can anybody give me detail instruction, how i can
* Configure RedBoot (Cygwin) for simple LPC2106 board (just one chip +
RS-232 drivers)
* build Redboot image, flash it in to the chip
* simplest test program & minimal eCOS configuration, that can fit
64Kb RAM
Is it real to make simple demo (as eCOS application - not simple C prog :) )for
64kByte of RAM (LED flasher, etc.)?
