Can't get ARM-USB-TINY-H to work, no way, no how

OK, I’m frustrated. I’ve been using Crossworks with their Cross Connect, but now at work they need a quick ARM project using free tools and an ARM-USB-TINY-H, and I’ve spent the entire day trying to get it to work with either IAR or the Olimex Eclipse/GCC package. OS is Windows XP. I’ve gone through every permutation of downloading/installing/uninstalling/cleaning the drivers (except the correct one, of course). It simply won’t connect.

Then I brought home the A-U-T-H to try it on my Windows 7 machine with Crossworks and couldn’t make it work there either. I read that 64-bit operation is a problem, but that doesn’t explain my troubles at work.

So I’m looking for either the magic words to make this device work on an XP machine, or a recommendation for another JTAG device in that price range.

And I have never appreciated Crossworks and CrossConnect so much!

you did not explain your problem at all. have you read this http://www.catb.org/~esr/faqs/smart-questions.html ? what do you mean by “not working”? what errors are you getting? what have you tried so far to resolve those errors?

It probaby kicks Olimex’s butt in every respect

I have Bus Blaster V1 (my own V2 is on its way) and run Win7 Pro 64 bit with OpenOCD and it works like a charm with a AT91SAM7XC512

Granted, I didn’t give as much info as would be desirable, but that’s because I’m writing from home and don’t have the error messages in front of me. The Windows 7 / Crossworks error message is “Cannot find FTDI driver for USB device (vid = 0x15BA, pid = 0x002A…)” but I don’t actually care if it runs on my home system, so I’m not particularly interested in following that up.

I know that at work I got something similar to this (I grabbed this text from a forum post somewhere):

Warn : Unable to open FTDI Device…

Error: unable to open ftdi device: …

But I don’t remember the details of the WARN and ERROR text.

I was hoping that there might be some default “yeah, in 80% of these cases it’s XYZ”. If not, I’ll have to try again on Monday when I’ve got the errors in front of me.

I had all sorts of misery with the FTDI drivers on Windows 7.

Where did you get the drivers that you’re using from?

In the end I had to use the info from here:

http://www.olimex.com/dev/pdf/ARM/JTAG/ … rivers.pdf

To remove the drivers (you will need to use an application from FTDI that properly removes them: http://www.ftdichip.com/Support/Utilities/FTClean.zip

Then get the drivers from http://www.olimex.com/dev/soft/arm/JTAG … 20808).zip

And follow the instructions from the README.txt file (things are not as straightforward as you might think…)

I found that I had to use the FTClean app more than once during the learning experience.

Hope that this helps
