Olimex LPCE2294 Poor documentation and support.

Started by arm_techie arm_user December 9, 2006
I am a newbie to this field. I recently procured an Olimex LPCE2294
Microcontroller Ethernet Rev B board. I tried uploading the test software
given by them on their site. I could not do. I am really surprised to see
such a poor documentation support and test program support form Olimex. Its
definitely very hard for a newbie to work on such a kit. I also request
Olimex support team to provide still more documentation support for their
kit in particular LPCE2294 Rev B.
Is anybody over there successful in using Olimex's LPCE2294 kit. If you are
successful can you send me some test programs that can run on my
Microcontroller board.

What error if any did you get? Was the program sucessfully loaded?

If you are a newbie, take your time, as ARM MPUs are quite a
handful, and can take quite a bit of time to understand, regardless
of the amount of documentation. Download the MPU user manual
from the NXP site, which may help explain a few things. Look at
past messages on this group, as many helpful resources have been
mentioned in the past.

Good luck,

I have an Olimex LPC-L2294 board myself, among with a couple of other boards.
I have some years of experience doing microcontroller applications on
8 bit micros (Motorola, 8051 and PIC) but I still had a few problems
getting started on the ARM because it is very different to the 8 bit micros.
About documentation, I've found the board schematics to answer most questions
that are specific to the Olimex board, although they should publish an errata
as I do know there are at least a couple of confusing things on the E2294 board.
The documentation I really use is the chip's user manual and I sometimes peek
at the ARM instruction set guide for debugging purposes.
As for example code, I've found there to be plenty around,
and even if it's written for a different LPC2000 series chip it usually
will run without any major modifications on another chip as long as it
has all the peripherals used in the code.
I've found this web site to have some good examples for the GNUARM toolkit:
http://gandalf.arubi.uni-kl.de/avr_projects/arm_projects/
Try downloading the GPIO example to start with, it should work on your board
if you just change the definitions of where the buttons and LEDs are connected.
Use the Philips LPC2000 flash utility to upload the hex file once you have
compiled the code. Be sure to remove the bootloader jumper after flashing
as otherwise the bootloader can't exit (I ran into this myself, being used to
the Motorola bootloaders which allow you to exit from the bootloader if needed)
