[Question] Flash PrimeHub with pybricksdev on Mac ? #420

Closed Vinz1911 closed 3 years ago

Vinz1911 commented 3 years ago

Hi @dlech @laurensvalk

I have a question about the flashing process for the PrimeHub. Personally I'm not a big fan of chrome or using a web ide. I write my code directly on my Mac. so i played a little bit with pybricksdev and it work like charm with the technic hub. I would like to know If it's possible to also work with the Primehub and pybricksdev. I installed dfu-util but I run in an issue (I used dfu restore + technic hub firmware <- is this the correct firmware?) :

dfu-util 0.10

Maybe you can light up me here :) Thanks and best regards.

I've just pushed a potential fix. I haven't tested on Windows or Mac yet.

I used dfu restore + technic hub firmware <- is this the correct firmware?

No, you need to use the primehub firmware with the SPIKE Prime hub.

The usual flow is:

# back up the official LEGO firmware
pybricksdev dfu backup my_backup.bin
# flash the Pybricks firmware
pybricksdev flash primehub-firmware.zip

It doesn't look like dual-boot is an option with pybricksev at this time.

Thank you for the fast reply :) I'm a bit confused, where can I find the latest build for the Primehub?

I will try, thank you very much. That's not a problem, I don't need the Dual Boot Option.

You can find the latest builds here: https://github.com/pybricks/pybricks-micropython/actions/workflows/build.yml?query=branch%3Amaster

Click on the most recent (top) build and scroll down to "Artifacts".

Hi @dlech

Your fix is working well :) It was possible to flash the firmware now without any problems.

But it was not possible to start the Primehub just with the Pybricks firmware for the Primehub. Do we need the Dualboot to run the Pybricks Firmware ?

But I think the Bug can be closed :)

What command did you run?

Vinz1911 commented 3 years ago

i flashed it with:

pybricksdev dfu restore primehub-firmware.zip

dlech commented 3 years ago

That will just copy the .zip file directly, which doesn't work. Use pybricksdev flash primehub-firmware.zip instead.

dlech commented 3 years ago

pybricksdev dfu restore my_backup.bin will restore the firmware backed up with pybricksdev dfu backup my_backup.bin.

Vinz1911 commented 3 years ago

Awesome! Everything works now as expected :)

Thank you!!
