Coolrunner and Amontec USB Key

Hello Dominic,

first of all I would like to thank you for this excelent piece of code. It works perfectly and we are very satisfied with it. We use it for programming STR711 chips with use of Amontec USB Key. There is one thing, that would make us more happier and life easier. In our device, we have daisy chain, which consist of STR711 (device #0) and XPLA3 Coolrunner cpld (device #1). I set up configuration (listed below). It is probably correct, programming of STR711 flash works nicely. I would also like to program XPLA3 in the same way (Now,I have to use Webapck with Xilinx PP cable). In Webpack, I’ve created xsvf with the full daisy chain (STR711 and XPLA3). For the start, only operation I’ve recorded was erasing of cpld. In openocd I performed following command:

xsvf plain erase.xsvf

Openocd halts with this message:

Error: ft2232.c:451 ft2232_add_pathmove(): BUG: pd → tlr isn’t a valid TAP transition

I’ll be happy to help you investigate this bug/TODO, because working of this would really help us. If it help you, I can send you the xsvf file.

Thank you for your (or anybody’s) advice

SVF Player ( Serial Vector Format ) for Amontec JTAGkey is ready.

It is free, and you can take it from:

http://www.amontec.com/jtagkey.shtml

This SVF Player gives new features to the Amontec JTAGkey:

  • upload Altera, Atmel, Cypress, Lattice, Xilinx FPGA / CPLD with your SVF files.

  • upload your AVR processor via Serial Vector Format file.

  • run your SVF files for your custom Boundary -Scan board tests.

  • re-use your .SVF file from your specific Boundary scan software to JTAGkey.

  • no .cfg file needed / no GDB/telnet port needed.

Linux version of the SVF Player will be provided very soon!

Have fun with svf2jtagkey.exe for windows (svf2jtagkey.so for Linux) !
