bootloader log issue

[zzzZ]

The chip we use is nrf52832 and the SDK is nrf5_ SDK_ 15.3.0_ 59ac345,
the booeloader uses the example project nRF5_SDK_15.3.0_59ac345\examples\dfu\secure_bootloader\pca10040_ble_debug\arm5_no_packs,
using JLINK to capture log

The problems are as follows:

1. When bootloader is booted normally, the log under bootloader is not printed

2. When using your nrftool to download via Bluetooth, the bootloader log is not printed.

3. When downloading through Keil, bootloader can print log normally


How can I make the log of bootloader print all the time.

Hello,

I find this strange. Are you running this on a DK? Is there some way for me to reproduce this on an nRF52832 DK?

Did you do any changes to the pca10040_ble_debug project? The RTT Viewer is a bit flaky some times. Have you tried to reconnect it after starting the nRF?

Best regards,

Edvin

Hello:

we are not running on nrf52832 DK, Running on our own hardware,
on your DK, will the bootloader log be printed normally every time it is powered on?

we change nothing to default project,The RTT viewer is reconnected after each boot

 It should, as long as logging is enabled and a debugger is connected (a debugger is required when using RTT logs).

Have you tried running it on a DK?

Other than the logs, is the bootloader working as expected?
