Add UARTE in DFU bootloader to update an STM32

[vonRollChristophe]

Hi,

I use the secure BLE Bootloader to update the nRF52840 (with S140).

Now I want to add a UARTE to update the STM32 connected to nRF52.

Do you have a solution to do that? All my tries have not worked.

Thanks for help.

Best regards.

Hi

What SDK version and S140 version are you using for development on your end here exactly? 

Please try debugging and stepping into the code to see which exact function it is that ends up returning this error on your end. You would need to set a breakpoint inside the function and step by step check what causes the assert. Also check if you have declared the module with NRF_LIBUARTE_ASYNC_DEFINE()

You can also check out this ticket for some details on using libuarte with the SoftDevice:  Use libuarte together with SoftDevice  

Best regards,

Hi,

I use SDK 17.1.0 and S140 7.2.0

Yes, I declare the module with NRF_LIBUARTE_ASYNC_DEFINE ().

I will check the configuration of the SDK, and the module initialization order, and debug in level 0 mode as you said.

Best regards.
