Unable to flash nrf5340.bin in the Getting Started example

mdoser · February 6, 2021, 6:21pm

Hi! I have a new out-of-the-box nrf5340DK and recommended Nucleo expansion board.
I am trying to follow the instructions in https://docs.edgeimpulse.com/docs/nordic-semi-nrf5340-dk however I can not successfully flash my nrf5340 with the downloaded nrf5340.bin file.
I first tried the “drag and drop” method but got the FAIL.txt message file which had the contents “error during erase”.
I then installed the nRF Command Line Tools and attempted to flash nrf5340.bin. I used the command line

 nrfjprog --program nrf5340.bin -f NRF53 --sectoranduicrerase --log

which terminated abnormally. I am including the log file contents below.
I do not believe there is a problem with the nrf5340 device itself as I am able to successfully flash and run the Heart Rate Monitor sample successfully.
Any help would be appreciated, as my task is to demonstrate Edge Impulse features running on the nrf5340 asap. Thanks!

@mdoser,

Are you flashing with the shield attached? I have the feeling something goes wrong sometimes with it (some pin conncected on the Cortex header or something?). Can you try without?
How are you flashing the heart rate example? Also with nrfjprog or drag & drop or via west ?

mdoser · February 7, 2021, 2:24pm

Hello!
I did have the shield attached, however after removing the shield and attempting to flash again via File Explorer drag-and-drop, I still get the same FAIL.txt message, and also when attempting to flash via the nRF command line tools (version 10.12.1) the process abnormally terminates in the same way.
I used the nrf Connect v. 3.6.1 Programmer app to successfully flash the heart rate demo via its drag-and-drop interface - this programmer accepts HEX files, which I believe are not the same format as the .bin files, which I believe are not compatible with this programming utility.
I will next try building the nrf5340.bin file using the Docker image or the SDK directly and flash the device that way. Any other diagnostic ideas would be appreciated - I am currently using Windows 10 , and will also try using Linux instead.
Thanks!

@mdoser I’ve emailed you the HEX version of the same image, and have pinged Nordic as well.

The weird thing is that I also have a board that has the erase error when flashing through drag and drop programming, but that board goes fine through nrfjprog (same version as you have, but on macOS).

@mdoser Nordic noticed this might be due to the readback protection, and running:

nrfjprog --recover

Might work.

Didn’t help getting drag & drop programming back for me, but might solve your issue when flashing with nrfjprog…

I was able to flash this hex file then start the edge-impulse-daemon, and my device was recognized and registered with my project. Looks like my issue has been solved. Thanks!

janjongboom · February 8, 2021, 7:48pm

We’ve now added the .hex file to the firmware download as well, I’m still unsure on why you ran into issues, hopefully Nordic will be able to clear it up!

Hi, I’m also facing the same issue.

I tried with the hex file, but still, it’s not connecting the demon.

In the device manager it showing these ports.

System: Windows 10
Tool: Edge Impulse serial daemon v1.13.3

janjongboom · May 11, 2021, 8:40am

@salmanfarisvp Some things to consider:

Recover the board first: nrfjprog --recover
Flash without any shields attached.
Do you see anything when you run edge-impulse-run-impulse --raw and reset the board?

salmanfarisvp · May 28, 2021, 7:13am

Thanks, @janjongboom, Sorry for the late reply. it was solved. I was running EI CLI same time while trying to connect the WebUSB
