EPM900 ICP for LPC936 not working

Avinash Sastry

Hi,

I'm using an EPM900 board with a LPC936FA as the bondout chip. So far I have been using it in Emulation mode - running my code through Uvision debugger - but now I want to load my code onto the LPC936 Flash and run it directly, without using uVision.

I have two queries regarding this:
1. When I configure the board for programming, and press 'LOAD', I get the error:
*** Error: This is not P89LPC936 device.

2. Is there a way to run the code directly on power-on without using uVision?

I have consulted the following threads before posting this and I have tried all the settings and configurations posted, but I keep getting the same error. - http://www.keil.com/support/docs/2648.htm - http://www.keil.com/support/docs/3204.htm

The second link given above, displays a timing diagram of the voltages expected to switch to ICP mode. I checked these voltages and what I got was 3 pulses of 2.75V each of width 12ms at intervals of 275ms on the RESET pin (P1.5). This is totally different from what is expected, so now I have no clue what's happening.

Hope someone can help.
Thanks,
Avinash Sastry
