How can I solve this memory error?

[lukelouyu]

hi, I have been facing issue and I want to figure out what type of reasons can cause it? Connection issue? Or sth else?

For installing my program into the zybo board, it sometimes works while sometimes pop up this error message. Like intermittently working.  

Here are some error message:

targets -set -filter {jtag_cable_name =~ "Digilent Zybo Z7 210351AD668FA" && level==0} -index 1
fpga -file C:/Users/lukel/workspace8/test_3/_ide/bitstream/design_7_wrapper.bit
targets -set -nocase -filter {name =~"APU*"}
loadhw -hw C:/Users/lukel/workspace8/design_7_wrapper/export/design_7_wrapper/hw/design_7_wrapper.xsa -mem-ranges [list {0x40000000 0xbfffffff}]
configparams force-mem-access 1
targets -set -nocase -filter {name =~"APU*"}
source C:/Users/lukel/workspace8/test_3/_ide/psinit/ps7_init.tcl
ps7_init
----------------End of Script----------------

15:56:02 ERROR    : Memory read error at 0xF8006050. Invalid DAP IDCODE. Invalid DAP ACK value: 0

Thanks

Hello @lukelouyu,
Do you use an external power supply?
I have found these forum posts with a similar issue which were fixed by
a) switching the micro-USB cable

b) changing the power supply

Best wishes,
Eduard

Thanks for your answer, I did not use the external power supply. I try to fix this issue by restarting my laptop.
