Hi,
I use a JLink-EDU to flash nRF52840 on macOS and meet an error. The JLink software version and error informations is below.

If I connect the nTRST pin of JTAG to reset pin of MCU, it works well.
I want to know what’s this error mean? Why it’s works well when connect nTRST pin?
Looking forward to your reply!
