Redboot and eCos

Started by vever ●June 7, 2011
Hello.
I would program an AMR7 LPC2138 with eCos and redboot.

But there is not enough RAM to load the program on it. (with a load
command).

I wonder if you know if I can directly load my program into flash and start
it by redboot from flash.
Or if I can load redboot and my program together into flash and make
redboot to start the program alone.

Thank you very much!

Vever

Yes, you can do that also.

Okay thanks!

I have just succeeded to do that (load program without redboot).

But when I load the program into flash via JTAG (openocd), it bug the jtag
communication, and I can't connect to my card with Openocd. (I must erase
flash with FlashMagic and re connect with openocd)

So, I come back on my question.
You said I can load redboot and my program together and configure an
autostart of my program by redboot.

Do you have a guide which is about this ?
Or someone who has already done that could help me ?

Thank you !
