[ECOS] eCos port for Olimex LPC-E2294 development board

[ECOS] eCos port for Olimex LPC-E2294 development board

[Sergei Gavrikov]

Hello

There is an info for the owners of Olimex LPC-E2294 development board.

An eCos port for Olimex LPC-E2294 board (hardware rev. A) is done. A
few days ago I finished a porting RedBoot/eCos for this target. The
port needs no hardware corrections on the board. I heard folks do the
corrections on the board to turn on a 16-bit mode for the Cirrus Logic
CL CS8900A ethernet controller.

There are diagnostic channels support (UART0/UART1/LCD); Intel Flash
parts (TE28F320C3BD70) support; a Cirrus Logic CL CS8900A ethernet
controller (it had been wired in dumb 8-bit mode) support in the port.
Well, the http://sourceware.org/ml/ecos-discuss/2006-07/msg00062.html
problem resolved.  There aren't SPI, I2C, CAN, etc. drivers.

The short story how to apply my things to run eCos on the LPC-E2294
development board (note: for recent eCos snapshots) leaves here:

Any notices about the port are welcome. The port is a pre-released thing :
an olpce2294-1.0.epk ecos package.

Hi,

Am trying to port ecos for the Olimex LPCE2214 using your post. I
think the only difference between 2294 & 2214 is externel flash. So i
have added AMD(AM29F800) flash driver before building Redboot. But
obviously iam missing some thing. Am really trying hard for this to
get work. Here am posting the error msg with this after loading the
Redboot image on my Target. Please help me out.
error msg:

FLASH: driver init failed: Driver does not support device
Sorry, FLASH config exceeds available space in FIS directory

Exactly what flash device is on the board? Have you checked it is
supported by the AMD29f800 device driver?

Thanks Andrew, I got it fixed.. The mistake is, I have added AM29F800
instead of AM29LV800.. .Its working.
Thanks all.
