ERROR: JLinkARM DLL reported an error. Try again. If error condition

ERROR: Semiconductor and provide the generated log.log file to them.
we bought NRF52840 to test other boards, firstly a problem happened, when change a new NRF52840 the testing could pass, so we doubt the firmware inside it was lost, how could we solve this problem?

Hi Pan,
Are you using nRF52840 DK?
Please make sure the power supply is 3.3v. You can check by the J-Link Commander to see the detected VTref.
Please upload the file named log.log under C:\Users\Administrator. Thanks.
