softdevice enable in Application crash if it has already initialized in bootloader

Yes but I use my workaround as described in my last paragraph.

@mamarceau: Are you still experiencing this issue?

I'll see If I could create a stripped project bootloader/app that reproduce this. As for the base addresses, it is done in nrf_ble_dfu.c:765 err_code = sd_softdevice_vector_table_base_set(BOOTLOADER_START_ADDR); and nrf_bootloader_app_start.c:172 err_code = sd_softdevice_vector_table_base_set(start_addr);

did you set the vectar table in MBR and forgot to change it back to softdevice base address? I am just trying to think loud all the options that could cause this.

can you step and see if the SVC instruction causes the hardfault or does this happen inside the softdevice`? Does your application_fault handler gets called? I think we need to investigate it more, can you help me reproduce it at my desk by uploading project or some files, if you cannot upload here then please open a ticket in mypage in support and i will take it over.

Just tried to add nrf_delay_ms(20) (also tried 100ms) between the sd disable and application jump and still doesn't work.

Yes, 100% reproductible. If I enter in bootloader and directly jump to application, it works. If I initialize sd and ble and then I jump in app, regardless if I disable sd before jump, it fails. I use the example code, I never switch to RC clock. Let me try the 20ms delay.

The title for this question says that app crashes on softdevice_enable if it is already enabled. But your code shows that it is disabled in bootloader before it jumps to app.

is this 100% reproduceable? are you using internal RC for LFCLK? what happens if you add like 20ms delay after softdevice_disable and then jump to the application? I am just wondering if there were still any calibration on going when you do softdevice_disable, because calibration is done asynchronously within softdevice and notified with power interrupts internally.
