Problems with Openocd and Altera USB-Blaster

Development Boards MicroMod
1

Hello,

I compiled an actual GIT of openocd with the FTD2xx drivers for use with Altera USB-Blaster.

(For compilation I used cygwin on a system with win xp and I followed the tutorial from mifi)

The compilation was successful, but when I’m trying to run openocd I get some errors.

Does anyone know, whats wrong?

Hello.

stefmaster, I’m have same interests and got same (wrong) results. It is not a hardware problem, USB Blastrer succesfully connect to my board under UrJTAG.

hello,

yes, thats right. UrJTAG is running.

When I try to start OpenOCD, it detects that the USB-Blaster is present, but it fails to initialize it.

Auto-detection fails and defining TAP definitions make no sence.

I don’t know why. I’ve already checked, if there is any other application, that has access to the Blaster or the driver.

Any suggestions?

regards
