Eclipse locks jtag

After starting Eclipse (and not doing anything 

with it) it locks jtag. After this I cannot program  

the FPGA, etc. This is what I get: 

 

-- 

$ jtagconfig --enum 

1) USB-BlasterII [USB-1] 

Unable to lock chain - Chain in use - check ? on 127.0.0.1 

-- 

 

This behaviour suddenly started today. After closing Eclipse  

everything is back to normal: 

 

-- 

$ jtagconfig --enum 

1) USB-BlasterII [USB-1] 

031050DD 10M50DA(.|ES)/10M50DC 

020D10DD VTAP10 

-- 

 

Any idea how to prevent this locking? 

 

Thanks, 

Jos
