mfw_update sample app fails

rabarar

Anyone successfully update the feather to the 1.3.7 firmware? When I attempt to do so, I get the following error:

Taking a closer look at the python docs for pynrfjprog this looks to be a WINDOZE only app… grrr

jaredwolff

@rabarar this should work on all platforms. It only uses the serial interface. The other dependencies are for jlink

https://github.com/NordicSemiconductor/pynrfjprog

jaredwolff

What version of python3 do you have installed? What about the pynrfjprog library?

rabarar

so python version on OSX with homebrew is Python 3.11.10 (main, Sep 7 2024, 01:03:31) [Clang 15.0.0 (clang-1500.3.9.4)] on darwin and pynrfjprog is 10.24.2

rabarar

@jaredwolff I’m sure you saw it in the log, the error specifically is: Error caught in parse_stat_response: Key not found: 'rc'\n\textra: [Probes./dev/tty.usbserial-510] [ModemUARTDFUProbe] Unknown runtime error: Found end of content before end of string.\n\textra: [HighLevel] Failed programming the device."

jaredwolff

I did see the errors yes.

Usually on Mac the device shows up as /dev/tty.SLAB_USBtoUART are you sure you’re using the right port? I assume you loaded the mfw update firmware without an issue? Make sure you close all open console sessions (serial port logging etc) as it will interfere.

rabarar

@jaredwolff - okay I found the issue. If you download the firmware link from the nordic page, it will automatically uncompressed and leave a folder of the items in your download directory. Typically, one just recompresses the folder to restore a zip archive. But that is what created an issue as it likely added an OSX-Specification artifact to the zip file. On a hunch, I thought I’d try grabbing the zip file with wget and see if that made a difference. And indeed it did and everything worked as expected … may be worth adding a caveat to the docs for MacOS … btw - the device on OSX is /dev/tty.usbserial-510

After updating the firmware, reloading the at_client app, I can confirm that the new firmware is installed:

at
OK
AT+CGMR
mfw_nrf9160_1.3.7
OK

jaredwolff

Ahh yea tricky! Glad you got it straightened out 😃
