Updating Serial DFU command requires bootloader verify python script to be run before it starts successfully

[urvilsuthar]

Hello,

I am working on NRF52840 DK board, trying to run Mesh DFU example code. 

The issue I am facing is that I have to run Bootloader Verify python script before the Serial DFU command every time.

Hi,

The device is reset as part of the bootloader verification. I suspect there is some issue with the device or bootloader that makes it hang, and the reset during bootloader verification makes it work again. Have you experienced any other issues with the device? Does it seem to work as intended, before / after the failed DFU attempt?

Regards,
Terje

Hello Terje,

Working with: nrf5_SDK_for_Mesh_v5.0.0_src AND nRF5_SDK_17.0.2_d674dde using SES

Boot-loader Verification and reset command required all the time before starting the DFU process In Win10. Today I tried the same process and found that In Ubuntu20 its works without Boot-loader verification some times.

Yes, Required Boot-loader verification and Reset commands every time DFU fails in Win10.

Let me know if below issue required new post.

Now, Another issue after starting DFU is, it stops every time after uploading 33 segments of data. for more details please fine below logs and RTT logs.    

33 Segments of Data: using armcc Boot-loader

240/more Segments of Data: using gccarmemb Boot-loader

Failed to upgrade target. Error is: Lost connection in the middle of the transfer

Possible causes:
- bootloader, SoftDevice or application on target does not match the requirements in the DFU package.
- baud rate or flow control is not the same as in the target bootloader.
- target is not in DFU mode. If using the SDK examples, press Button 4 and RESET and release both to enter DFU mode.
- if the error is ERROR_BUSY at the beginning of the DFU process,increase the value of PAGE_ERASE_TIME_MAX by few milliseconds.

Thanks,

Solved DFU issue by changing Serial port from ttyUSB0 to ttyACM0 in Step 11.
