Can't read device from JTAG chain, highly likely having a burnt chip, how to fix?

board: Spartan 6 SP05

Suddenly can't find any device on JTAG chain 

error : A problem may exist in the hardware configuration. Check that the cable, scan chain, and power connections are intact, that the specified scan chain configuration matches the actual hardware, and that the power supply is adequate and delivering the correct voltage.

 

Did a JTAG chain debug, TDO is always 1

Think one of the chip is burnt while running code, is there any way to fix it?

Can I send the board back to have Xilinx to fix it?

Try to re-install JTAG drivers if this seems to be driver issue. If it gets detected then you run the BIT test from here

If not, you can contact https://www.xilinx.com/alliance/memberlocator/1-64bn80.html whizz systems for any repair which your board might need here.

The drive can connect to other Spartan 6 devices, I can try the whizz see if it works
