Inexpensive ARM JTAG Programmers

I'm using the Code Red RedProbe+. At $150 it works pretty well if you're working off the Code Red toolchain, but as far as I know CR won't release any of the interface information on it, so you're kinda up a creek if you need something that'll just work with a hand-rolled chain.

I have a hand-rolled chain. And besides, what I'm mostly looking for is a tool that I can give to the customer so that he can program boards on- site, without me there.

I left one of those with a client to program Atmel AT91SAMsomething ARM7TDMI chips. I watched him use it (OpenOCD under Windows), and I heard no complaints afterward.

Mel.

Do you have a "pro" case for your board? Doesn't help if the tool is more "pro" than the product.

The Olimex ARM-OCD-USB is probably the best bet for an inexpensive and also widely supported ARM JTAG. The most widely used "pro" JTAG is the Segger J-Link but it's just a weeee bit pricier.

There's an older, inexpensive parallel-port Wiggler JTAG and numerous clones but parallel ports are few and far between nowadays.

I'd say, if the Olimex works and your toolchain supports it, that's the way to go.

Yup. I've decided that Rose-Bopla is my manufacturer of the year. They make a nice case, and they're willing to talk to low volume folks like me.

How about a bootloader that works through the UART ?

For large enough values of "weeee" ... ;)

That would cost my customer a whole lot more in my time than a $50 JTAG pod.

How about Open J-tag?

It is limited to a few devices.. but should work with cortex-M3

It might be too late for this job but the cheapest way is to use one of the FTDI USB cables - USB at one end and TTL level uart at the other - free PC drivers make them look like COM ports.

Damn ! I just noticed that you are using TI/Luminary ARM not an NXP one ....

Well, if you were using an NXP (or ST) ARM with a built in UART bootloader you could use one of the FTDI ..............

I'm going to have some coffee now !

If you expect to do this more often, you might want to try

Hmm, I had not seen that before, thanks!

However, their disclaimer "J-Link Lite is only delivered and supported as part of Starter Kits. It is not sold to end customer and not guaranteed to work with custom hardware." is kind of a bummer.

My J-Link is a fairly old one (V 6.00 hardware).
