Do you have working bridge code that can ICP a LPC908?

ICP should work across the range of LPC900 parts (except for some very old LPC932 parts).

Please cfm you ICP bridge is working 100% with the LPC908.

There are some LPC900 ICP files on the Yahoo LPC900 group which show the pin connections on the different LPC900 parts. You will need to register to the LPC900 Yahoo Group to download these files from the file section.

I would assume the LPC938 has the same ICP pins as the LPC935 and other 28pin parts.

See page 15 here

Ans the P89LPC938 User Manual Page 120 Says

"In-circuit programming (ICP)
In-Circuit Programming is a method intended to allow commercial programmers to program and erase these devices without removing the microcontroller from the system. The In-Circuit Programming facility consists of a series of internal hardware resources to
facilitate remote programming of the P89LPC938 through a two-wire serial interface. Philips has made in-circuit programming in an embedded application possible with a minimum of additional expense in components and circuit board area. The ICP function
uses five pins (VDD, VSS, P0.5, P0.4, and RST). Only a small connector needs to be available to interface your application to an external programmer in order to use this feature."


**** Timing is very critical 50uS pulses etc **** if there is any additional rise times from R's, L's and C's the timing will be off and the part wont program correctly.

This is why NXP(Philips) recommend a commercial programmer and only support such.
