Hi all:

First of all, sorry about my poor english (I'm spanish).

I'm just starting with ARM7 and i own a LPC2368 evaluation board.

I've several questions to the group.Since i'm using linux (ubuntu) on my
desktop computer i would like to keep it as
my development OS but its not a "must". I can switch to windows if linux is
not well supported.

Questions:

1) Is there anybody here using Linux and developing for the LPC23xx?
Can you point
me to some "clear" tutorial on how to build a development enviroment for
the LPC23xx uCs?

What i have working so far:

- Toolchain: Downloaded from GNUARM.com. Is this the good one?
- Eclipse: There are several tutorials/how-tos for linux/windows. Any
better setup?

What i still miss:

- LPC21ISP: I've downloaded and compiled version 1.48, but it doesn't
supports my LPC2368
(I know this is a little off-topic here, but maybe somebody can
confirm a version working). Any other solution for ISP on linux?

- LPC23xx CFG files for OPENOCD: I also own an Amontec JTAGTiny
interface, but its difficult to
find properly working CFG files. Any help here?
Any general recommendation here? what is people using in linux?
Eclipse+openOCD? Any other setup?

2) I came from the AVR world (ATMegas), where there are lots of
libraries for the peripherals and
some other general purpose tools (Register calculators, Delay
routines, etc)

- Are there any "must-have" libraries or tools that you use? I've
only found "PLL-Calculator".
I see lots of spare examples but not a complete guide, different .s
and .h files so its kinda
hard to know which one is the best option.
Regards,

Jorge.

Keith's Bitometer is very useful. I posted a link to it the other day.

If it works - why better? ;-)

lpc2k_pgm works fine for me:
http://www.pjrc.com/arm/lpc2k_pgm

And this is also terminal program.

Yes it works, i was just curious about other options.

I know lpc2k_pgm, but it doesn't supports my LPC2368 (as depicted on the
documentation).
This is a copy+paste of the console when running lpc2k_pgm:

Port "/dev/ttyUSB0" opened at 9600 baud
Baud rate set to 115200
Reset CPU (into bootloader)

Entering Bootloader Mode
Reset CPU (into bootloader)
Attempting baud sync......................Baud sync sucessful

Download Canceled:
Unknown chip ID: "369162533".

Perhaps you have a new Philips LPC chip which does not
have its ID string and sector map defined in this program?
Please contact p...@pjrc.com. Please include an exact copy
of this message and any info about the chip and other
hardware you may be using. Thanks :-)
Same results with lpc2isp (v1.48), my LPC2368 isn't supported.

Any other tools?
Thanks for helping anyway :)

I am using OpenOCD (svn rev 738) and the Amontec JTAGKey with no

Hi,

for the tool-chain try http://www.gnuarm.org/. gnuarm.com and .org has
different content. .org seems to be more up to date.
The official homepage of gcc (gcc.gnu.org) does not list an official arm
package maintainer. This means both "gnuarm.com" (registered by Richard
Collins) and "gnuarm.org" (registered by embedded.cl) has unofficial
binary packages.
So if you want to be sure get the latest source from gcc.gnu.org and
compile for yourself. (This is not a simple task. Also you need to
compile the standard library. You have several options here (newlib,
ucLibc, etc).)

Wow! I didn't noticed the difference between .COM and .ORG, thanks for
warning.

The site gnuarm.ORG points to a codesourcery toolchain. What about this
one? Any thoughts on this one?

And about the libs, newlib seems to be the most used, any recommendations
here?

Thanks for helping :)

Hmm... it works with my 2364 without problems.

Maybe is worth to try change id_string in chip_info[] table (file
chipinfo.c) to chip ID, and recompile the program?
