Problem on downloading bitstream to a Stratix 10 MX board

Thanks for your reply!

No, I can't. But when using the external power supply, I got different error messages:

(18948) Error message received from device: Detected hardware access error. There is a failure in accessing external hardware. (Subcode 0x0032, Info 0x00000000, Location 0x0000B800)

(20072) A PMBUS error has occurred during configuration. Potential errors: incorrect VID setting in Quartus Project. The target device fails to communicate to smart regulator or PMBUS Master on board.

(209012) Operation failed.

After searching online, I find the following solution to this error:

It seems that I have to configure the DIP switches to the JTAG only mode. Thus I change the DIP switches to the following configuration:

SW2[3:0] = 1111, SW1[3:0] = 1111;

According to the user guide of Stratix 10 MX (https://www.intel.com/content/www/us/en/programmable/documentation/cbc1517362051825.html#sgk1519171036412), I changed the SW2 to set up the JTAG only mode, as shown in the following picture:

However, with this DIP switching configuration, I got the message "Unable to scan device chain. Can't scan JTAG chain. Do you want to open the JTAG Chain Debugger to troubleshoot the JTAG chain?" I guess this error is caused by the wrong setting of DIP switches. A picture of the correct DIP switch setting for the JTAG only mode will be greatly appreciated.

Thanks,
