Inexpensive JTAG adapter for STM32 / IAR ?

Started by Roberto Waltman June 6, 2011
As subject line says - Can anybody recommend a (cheap) JTAG adapter
that works well with IAR EWARM and ST Cortex M3 chips?
Trying not to buy another Segger ...

Thanks,

Because of performance or because of cost? I see a couple of them on eBay, fairly recent versions, for $48.

Cost - Is to have something at home, to avoid carrying too many things from/to the office when doing some remedial work on weekends. (And a few personal projects down the road.) Thanks for the pointer. -- Roberto Waltman [ Please reply to the group. Return address is invalid ]

I thought they didn't have one that works straight out of the box with IAR, but didn't check for a long time. Will take a look, thanks. -- Roberto Waltman [ Please reply to the group. Return address is invalid ]

I hear you on that. Mine is an old one, IAR always whines at me that I am "missing out on advanced functionality". On a related note, I was very pleasantly surprised this weekend. I was given an Atmel SAM3S-EK board, and I did not have to do any futzing with magic macros, custom flashloaders, assorted buggering about with linker and debugger settings, or anything of the kind - I just set the target chip in IAR, hit download and it Just Worked. (Exactly the way I would expect it to work for any device that has all on-chip flash, btw). Anyway, something has been significantly improved here. Trying to get IAR talking nicely to LPC2103 and Atmel SAM7 chips was an exercise in horror - it seems like the only sane way to do it is to take someone else's working hello world project and strip stuff out.

The SAM-ICE is a cheaper J-Link, Same H/W, Atmel locked firmware. It is blue instead of black or yellow, (I happen to have a golden one). -- Best Regards Ulf Samuelsson These are my own personal opinions, which may or may not be shared by my employer Atmel Nordic AB

Thanks for that! I'm ordering one. (I didn't notice this post till today...) Since this thread started I also found that Segger is offering a Jlink "educational version" for $60. From their web site: "The offer includes free use of Flash Breakpoints. The only limitation is that it may not be used to develop a product. ... It is not sold to companies. ... Even if you are a professional programmer you are welcome to use J-Link edu for personal interests at home" -- Roberto Waltman [ Please reply to the group. Return address is invalid ]

You can beat that price by ordering an STM32-Discovery kit for about $12.60. That kit includes an ST-Link MPU that you can disconnect from the onboard STM32 and connect to your board with 3 wires for the SWD (Serial WIre Debug) interface. There are jumpers on the Discovery board to disconnect the onboard MPU. It works. I used it for a while until I invested in a ST-Link kit. It worked fine with IAR after I set up C-Spy to use serial wire debug. I'm getting to be a fan of the STM32 series. Good hardware, good support tools, a wide range of chips and a pretty good firmware library. I've started with a lot less on other systems in the past. Mark Borgerson
