nrf52382 firmware program lose

[lulu]

After nrf52382 is written into the firmware program, the test runs OK. After it is placed for a period of time, it is checked again. It is found that it is not running. Use the JLINK tool jflash to read the data. Why is this

[Jørgen Holmefjord]

• Are you experiencing this on a DK or a custom board?
• If running on a DK, is LED5 on/blinking?
• How is the board powered?
• Have you measured that the voltage is correct when you experience this issue?
• Which FW are you running on the board? Did you make any modifications?
• Are you seeing this on a single board, or on multiple boards?
• Can the problem be recreated consistently?

It was encountered on the customized board; it took a long time to place, and there was no power when it was found out; the code modification was relatively large, and 0.1% of the boards had this problem, with more than 20 boards.
