Works great with latest BrJTAG v2.0.5. Good job, Thanks.
When used with the zJTAG.exe software freely available for download on their website, I have found this product to be excellent for use in de-bricking LinkSys routers. Although I have fabricated a custom cable for my particular application, it is very nice that this item also comes with ample jumper wires & a generous size two-row pin header (more than enough for several routers) allowing you to solder a permanent JTAG header into/onto your router, if desired. I would highly recommend this product to others. It is a great value, it is easy to use, and it works very well !!
I rarely write reviews. Ever. This device is like the bus pirate on steroids with a true 20-pin ARM JTAG header, and it also does 1.8v. Lots of devices I work with are 1.8v so this is quite useful. With the two MPSSE channels on the FT2232H you can do UART/SPI/I2C, simultaneously with JTAG. The PCB itself is VERY durable and made of high quality materials. This device was really well designed. I couldn't be any happier with this product. It's like a Buspirate on steroids.
Works perfectly with OpenOCD. Tested on STM32F4xx. I've had it get up to 30 kB/sec for flashing. It can probably do better.
