Nordic 52840 BLE OTA DFU in Liniux by Nrfutil

[xiang san]

Hi,

I have a question ,According to the official tutorial，I succeeded BLE OTA DFU in windows system by nrfutil ,however, when I use the nrutil tool to update the firmware on the liniux system, I don't succeed. Do I want to know the difference between the two systems?

In windows system my last command is "nrfutil dfu ble -ic NRF52 -f -pkg C:\Users\Administrator\Desktop\feida_dfu_package.zip -p COM5 -a C1646DCFDA58";

In liniux system my last command is "nrfutil dfu ble -ic NRF52 -f -pkg /root/download/feida_dfu_package.zip -p ttyACM1 -a C1646DCFDA58"

then everything else is the same.

Thanks！

Hi,

Are you getting any error messages when you run this on Linux? If so, please post the full log here. Here are also a couple of things you may try:

1. If you're using J-link, try to disable the mass storage class as explained here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/guides/tools/nordic_segger.html#disabling-the-mass-storage-device-functionality

2. Try to run the command as root in case there is a problem with permissions. E.g. sudo nrfutil dfu ble -ic NRF52 -f -pkg /root/download/feida_dfu_package.zip -p ttyACM1 -a C1646DCFDA58"

Hi,

Thank you for your suggestions, but they don't work. Here's the error message:

What is needed here is the AMD file,but our platform is the platform file of ARM architecture,I think my question is here,can you provide a solution to this problem? Thank you,or do you have a different opinion?

Hi,

The pc-ble-driver-py dependency is only officially supported on x86, so we are not including ARM libraries in this distribution. It is however possible to build the library from source if you wish to try that. Build instructions can be found here (I think it's easiest if you can install it through vcpkg): https://github.com/NordicSemiconductor/pc-ble-driver-py#building-from-source

Edit: Maybe you are aware of it, but I forgot to point out that nrfutil v.6.x.x requires Python 3. I notice from the crashlog that you're currently using Python 2.7.x
