Why my custom board can't be detected by jlink after download softdevice

[GuoZhirong]

I make a custom board with nRF52832, the nRFgo Studio can find the device before I download anything, then I down do erase all and download the softdevice132, after this I want to download the app to the board, but it failed, I found the Jink can't detect the device;

how are you trying to download your app to your device? using nrfgo or KEIL? flashing softdevice from nordic should not in any way affect the ability of jlink to detect the device.

Hi, we meet the same question. Before download the soft device, it's ok.After both keil and nrfgo can not detect the nrf52 Chip.

Is it just the softdevice you flashed? or is there any application and/or bootloader?

Please make sure that you are supplying enough power to the input pins. Since the original author did not respond to my questions, it is little unclear what they did.
