NRF_DESKTOP prj_keyboard.conf configuration not compiling with nrf52840 Dongle

[melt]

Hi There

I am getting the following error when porting my code to the PCA10059, using the nrf_desktop prj_keyboard.conf configuration.

if someone can assist why it cant find " No such file or directory: b0_CONF_FILE: ''

It compiles fine with when the 52840DK is selected

thank you in advance

Hi,

 

It looks like cmake is unable to pick up the "B0" configuration file (which is in ../configuration/nrf52840dongle_nrf52840/child_image/b0/prj.conf). Could this be a problem with the overall path length of your project?

 

Can you try to move it to a shorter path and see if CMake is able to pick up the variable correctly then?

 

Kind regards,

Håkon

HI Hakon, I dont think so, it works if I select the nrf52840DK.

It also works fine if I chose the normal prj.conf file.

Its only the combination of PCA10059 dongle and keyboard.conf that gives me that error

[Håkon Alseth]

Hi,

 

Can you share how you configure the project?

Either a screenshot of the vscode configuration window and/or the west build command echoed in the terminal?

 

Kind regards,

Håkon

Not sure exactly what you need here but here is the prj_keyboard.conf file. I have not changed it from original example,

Good Morning, After some more testing over the weekend. I loaded the DK build of keyboard.conf on the dongle. It does get picked up as an HID by a PC and so does the bluetooth, which tells me the program is running.

As soon as I try to change the GPIO to my Dongle pins the program stops. I do find it strange that the example does not work out the box on the dongle.
