Dear all.
I just got nRF52 DK and testing blinky based on KEIL and it works well. I tried one test, IF BOOT/Reset, and nRF52 PDK is not working after below sequence.
- Power off nRF52 PDK
- press IF BOOT/RESET Button and power on
- PC pop ups disk and could see bootloader relates files
- I tried to connect KEIL with JLINK but failed, PC couldn't recognized nRF52 PDK EVM
- power off nRF PDK and power on without press IF BOOT/RESET button
- there is no any LED blinking and if I try to connect JLINK with KEIL, couldn't connected due to couldn't recognized PDK
- so I pressed IF BOOT/RESET button and power on again and could see pop ups and some files inside disk so PDK is not damaged and it works
- I tried again without press button and there is no response, PC couldn't recognize PDK EVM and also KEIL couldn't recognize
nRF52 PDK EVM is working, PC pop ups when power on with button press, but looks not working with normal mode(without press reset button).
I have tried to find information but couldn't find something helpful so could someone help on this problem?
Many thanks. Louiey. : )
