Part Number: TSW1400EVM

error:Download Firmware
JTAG CHAIN BROKEN ERROR
The JTAG chain was broken while loading the firmware
I have changed many connecting cables, but I can't solve it. I can't download the data to tsw1400. I don't know if it's the JTAG port that is damaged. I'm in a hurry. Please help me solve it as soon as possible. Thank you.
I use the matching board of dac3162.
