When I execute the program jump, the log will be lost

[zl l]

As described in the topic, I wrote my own bootloader (located at 0x70000). When I restart from the app (located at 0x26000) and enter the bootloader, NRF_ Log doesn't work. There is no log output I want, Which kind man can help me？ Thanks

Hi,

Have you enabled and initialized the logger module in your bootloader?

Which backend do you use for the logger?

Do you reset the device using NVIC_SystemReset() or similar from the application, to enter the bootloader?

Best regards,
Jørgen
