Hi all,
I am trying to use a Linux standalone "UrJtag" to write a JTAG (SVF) file to EP2C5T144C8N Cyclone II device. It seems that the device is not recognized. See, message bellow! I am using a Altera USB Blaster cable. Firstly I am performing the follow command list:
cable usbblaster
bsdl path ep2c5t144c8n.bsd
detect
IR length: 10
Chain length: 1
Device Id: 00000010000010110001000011011101 (0x00000000020B10DD)
Manufacturer: Altera
Unknown part!
chain.c(149) Part 0 without active instruction
chain.c(200) Part 0 without active instruction
chain.c(149) Part 0 without active instruction
It seems that is not detecting this device "Unknown part!"
Someone know how to fix this problem?
Regards,
Rodrigo
It seems to be that your part is being detected, since uRJTAG returns the IDCODE read from the device via the JTAG interface. I believe that the problem is with this command:
bsdl path ep2c5t144c8n.bsd
You're supplying the name of the BSDL file, but not its path, as expected by the software. If the ep2c5t11c8n.bsd file is in the current directory you should enter the following command instead:
bsdl path .
Or if it is in a different directory:
bsdl path /path/to/directory/containing/bsdl/files
If it does not work that way either, i suggest you checking whether are you providing the right BSDL file.
Hope this helps...
