Re: [ECOS] RedBoot image for Olimex LPC-E2294

Hi Sergei

I have the Rev B Olimex LPC-E2294 board with the LPC-2214 CPU and 1MB of Flash (MX26LV800T).

Do I need to apply all the patches from the 

bitbucket.org/tickling/olpcx22xx/

repository?

Thanks, Peter

Hello Peter,

What's board revision do you have?
http://olimex.com/dev/lpc-e2294.html
http://olimex.com/dev/lpc-e2294rb.html

These boards have the different flash parts. eCos v3_0 has HAL for old
(Olimex now says 'obsolete board') Olimex LPC-E2294 board. If you have
the new one, i.e. Olimex LPC-E2294 REV.B board, try this HAL from here
http://bitbucket.org/tickling/olpcx22xx/

Old Olimex LPC-E2294 had 28F320C3 Intel flash parts, new boards have
28F160C3. These flash parts have the different device codes, perhaps,
eCos v3_0 flash driver for olpce2294 target cannot identify your chip.
