Dear lpc2000@yahoogroups.com,

I would like to use the LPC2148 for a C project, but I can't get any
program to run on the processor. This is my first time using the ARM
microcontrollers.

I am using the GNUARM toolchain with GCC to write and compile code and the
Philips LPC2000 Flash Utility v2.2.2 to upload the hex files to the flash.
I am using the IAR KS2148 Kickstart Kit for LPC214x (w/ LPC2148) hardware
(made by Olimex).

I have uploaded many different hex files to the processor. Some hex files
I have downloaded from the internet "Compare Flash" OK after uploading,
but hex files I have compiled do not. I think this is because the local
copy has a NOP at address 0x14 and the flash copy has a checksum generated
by the flash utility at this address.

I have followed the "ARM Cross Development with Eclipse" PDF tutorial by
Jim Lynch which includes an example program using the GNUARM toolchain and
GCC for LPC2106. I made some modifications and tried to use the example
for LPC2148 (specifically, I used an lpc214x.h header file from a Keil
example, changed the IODIR, IOSET, IOCLR instructions to IODIR0, IOSET0,
IOCLR0 and increased the flash size in the linker script). Everything
compiles and uploads as I would expect, but the program does not run when
I take BSL high and reset the processor.

Does anyone know where I can find some example C code for LPC2148 with
header file, startup assembly file, and GNU makefile and linker script?

Failing this, does anyone know where I can find an example hex file to
test that the board and the Philips LPC2000 Flash Utility are working OK?

Kind regards,

Nic
