Olimex LPC-E2214 board - MX Flash part

Development Boards MicroMod

Hi,

I am planning to use eCOS on the Olimex LPC-E2214 board and need to know which Flash driver to use. I can’t find a datasheet for the actual Flash chip on the board - MX26LV800T, not even on the MX website.

Does anyone know which Intel/AMD flash this part is equivalent to?

Thanks

Peter

Thanks Chris

do you happen to know which Intel or AMD part this is compatible with?

There is no mention in the datasheet…

Thanks

I don't but you may not need to know. Have you read the NXP Application Note AN10605 "Running eCOS on LPC2214"? They use the Olimex LPCE-2214 board as the example and provide sample code. You can download a copy from:

Hi Chris,

yes, I have read the application note and I have built RedBoot accordingly, but when I burn it into internal Flash and reboot the board it doesn’t recognise the Flash chip…

The eCOS HAL implementation for Olimex LPC-E2294 assumes Intel Strata flash (28F160C3), which is what is on the 2294 version of the board.

The files that are mentioned in the AN10605 to overwrite the Flash drivers:

3 cp ./flash_olpce2294.cdl $ECOS_REPOSITORY/devs/flash/arm/olpce2294/v1_0/cdl/

4 cp ./arm_olpce2294_flash.c $ECOS_REPOSITORY/devs/flash/arm/olpce2294/v1_0/src

don’t exist in the eCOS 3.0 distribution that I have…

So I was hoping to find out what Flash driver to substitute by knowing what (probably) AMD driver to use.

Cheers

Peter

Those files are included in the zip file on NXP's site:

It looks as though it is using the generic AMD driver. I have no idea if they are intended for v3.0 though.

Thanks Chris

I’ll give those a go.
