I have a dev board from embedded artists with lpc4357.

I'm trying to enable the external ram (with iar+jlink) and download the program on it.

In my .mac file i put these lines but i have problems on the commented parts:

//SystemInit

//MemoryPinInit

Hello,

I attached two script files for KEIL µVision which work for the Hitex board (16-bit SDRAM) and the KEIL board (32-bit SDRAM). They are a little bit better commented than the IAR file you have, so maybe it helps.

The script file for the KEIL board should work for the embedded artists board as well, it seems to be a similar SDRAM type.

Regards,
