Hi Richard_P,


I was not able to see the problem "Error: Fail to reset Debug" on the board on my side. For Arria10, the command "qaurtus_hps -c 1 -b 18 -o s" can be issued without problem regardless of involving qspi flash or not. If cannot work, try to power off and power on the board again after a while and run the command again.

Anyway I see you connect two jtag cable at the same time. Just to avoid jtag cable selection confusion in the attempt with cable selection(quartus_hps -c 1/quartus_hps -c 2) , allow only one jtag connection at one time.

The problem is not due to Arm ds debugger configuration but is the on HPS side of the board and fpga side is working fine because the .sof file can be flashed.


Thanks.

Regards,
