There was an error in the documentation (Readme.md). When you type make -j, it builds all the targets at once : the code + additional targets that programs the pinetime with JLink.
You should use this command to just build the project : $ make -j pinetime-app
I've just commited an update to the doc that takes this into account.

@JF002 Thanks! I built per above then flashed via:
make FLASH_SOFTDEVICE
make FLASH_pinetime-appand everything works correctly, but the display is blank - is this expected? To be clear, I've had no problems w/ other projects, the display works fine, etc. Thanks!

No, this is not expected... The display should show something (battery level, and the time, 00:00 by default).
Did you try to push the button to see if it wakes the display up?
EDIT : if the softdevice is not flashed properly, the soft enters into a reset loop. Could you check that the soft device programming is ok? Here is the ouput of make FLASH_SOFTDEVICE using JLink:
$ make FLASH_SOFTDEVICE

@JF002 yes I pushed the button. 👉 ⏯️
The softdevice (and app) seems to be flashing OK:

Well I've no idea :/
Could you try to update your code to the latest commit? In 8daa830, a hardware reset if applied to the display, because sometimes, the display would not wakeup from sleep. Maybe it'll solve your issue?

@JF002 OK, so this is really weird, but I can repro it reliably, so...LMK what you think: I pulled the latest and flashed - same blank screen as always; so I tried running RTT terminal to see if any output etc. (none) - and then - I tried re-flashing (while RTT terminal was running) - and after flashing the softdevice, the display came alive for the first time ever! Cool! So I flashed the app, and the display went blank. 🤕 I then flashed the bosmoment firmware as a palate cleanser, and the display resulted in a mixed state of both - e.g. your date was still mostly visible (guessing there was no full refresh). So then I stopped RTT terminal and flashed the softdevice, then your firmware - blank as always; so I re-flashed the softdevice like last time: nothing - in fact, an error:

All of this is really weird...
In my case, I only flash my firmware (haven't tried other projects yet) using jlink without any issue. Did you try to apply a (full / hard) reset on the MCU after the programming? I think it's possible using nrfjprog and JLinkExe.

@JF002 do you mean like nrfjprog ---pinreset?

JF002
commented on August 15, 2024
There are 3 options : --reset, --pinreset and --debugreset. To be honest, I don't know what are the differences between these 3 options, but you could try them out.
