Free LPC2xxx bootloader update tool

Started by tildesign2 May 26, 2005
The earlier LPC2xxx ARM processors require a bootloader update in
order to protect the code from being read through ISP.
We created a free update tool that is suited to reprogram any number
of LPC2xxx microprocessors quickly and fool proof. The update tool
provided by Philips works just fine, but only for engineers and the
update job is quite tedious.
Our LPC2xxx updater has a command line interface, so it can be
integrated in a production tester as well.

An Engineer's Guide to the LPC2100 Series

This seems pretty similar to LPC21ISP
(http://guest.engelschall.com/~martin/lpc21xx/isp/).
How stable is this new utility? I am currently calling LPC21ISP from
Eclispe, and I occasionally get the blue screen of death when using it.
Thanks,

Matt

Interesting, I'm currently making some changes to it, including some error
checking, so I'd be interested if you could provide any information. I
will be feeding the changes back to Martin but they have to settle down a
bit first.

Hi Matt,

we bought about 320 LPC2114's as soon as they were available. These
needed updating. During this process everything went just fine. No
crashes at all.

I'd say, just try it for yourself, it's free.

After some digging, it turns out that it is not the LPC21ISP that is
causing the blue screen. Rather I have traced it down to a corrupt
USB-to-serial driver.
Sorry for crying wolf.
