[JTAG][openocd]Error: JTAG scan chain interrogation failed: all ones #130
Description
I’m trying to debug Cortex-A55 chip on FPGA but I keep getting the following errors:
(I type the command :openocd.exe -f scripts/interface/jlink.cfg -f scripts/board/k6.cfg -d3)

I guess my bitfile may have some porblems but trace32 work well using the same bitfile. Now i have no idea about it. Anyone can help me solve this problem or just give me some ideas and anaysis.
