nRF52811 First time programming procedure using J-Link

[Sai jyothi]

I have used nRF52811 chip in my custom board.

1. Please provide the First time programming procedure using J-Link (J-Link-Pro tool) interface.

2. We have a nRF52840DK board, erased the default binary then we flashed the custom binary using J-Link programmer (P18 on DK board), but observed that it is not advertising on Mobile App. Is soft device binary mandatory for first time programming on the chip. Please confirm and provide the details.

3. How can we get the log using RTT Viewer using J-Link programmer on nRF52840 DK board & nRF52811 custom board.

4. Please provide the memory layout details for nRF52811 chip with Soft devices and without Soft devices.

Regards,

Jyothi.

Hi

BLE communication won't work without the external 32MHz crystal running, so I don't think that it's not running if the board has been flashed with a working application. What "binary" is this that you have flashed onto the DK and/or custom board? How are you measuring whether the clocks are running or not exactly? 

Best regards,

Simon
