I’ve just bougth Olimex LPC-MT-2138 dev. board. Easiest way to test board - use Philips Flash Utility. I downloaded right wersion (V2.2.1 it’ undertand LPC2138 ID), set right jumpers positions (BSL is on, JRST is on) and nothing. Utility says that can’t comunicate with board. I tried to use hyper terminal - nothing again.

Mayby there is some hardware trouble? How can I chek It? My OS - WinXP SP2.

I read that boot loader can be erased in microcontroler’s flash. How I can chek it?

Also I bougth ARM-JTAG but not for a while yet use it.

HELP me please.

The most current version of the Philips LPC2000 flash utility is 2.2.3.

hmm… I have a similar problem. I got a new Olimex LPC2106 board. All the blink samples seem to be working fine but when I try to upload the FreeRTOS port, I get a ‘Cannot communicate with test board!’ after the progress bar goes some distance. I have LPC2000 flash utility version 2.2.3 on Win XP. Any ideas?
