platformio error "no such file or directory" grbl/driver_opts.h but the grbl directory is empty

[lappa1]

I'm trying to build a single board in platformio, as a test, but platformio looks for grbl/driver_opts.h but the grbl directory is empty. I'm using the STMF4xx build I downloaded
My aim is to eventually build for a GD chip that is not in the WEB BUILDER so this is just getting a feel for the software.
Any ideas?

Update. I found and copied the file into the grbl directly.
it now gets past that point but fails with #include "hal.h" compilation terminated highlighted in yellow??

You have to fetch the submodules.

I have already downloaded https:/github.com/grblHAL/STM32F4xx.git

[lappa1]

I used the Command prompt and Git clone rather than download and unzip and it seems to work?

[lappa1]

Just a question. Why does downloading and unzipping not work?
I have always downloaded and unzipped from GitHub, except when using Arduino Board Manager.

Why does downloading and unzipping not work?

Because github decided to not include the submodules which the grblHAL drivers depends on.

@lappa1 Hi friend, are you also using a GD chip to use grblHAL? I also need to use a GD chip to build a grblHAL project recently. Have you successfully built grblHAL on a GD chip, such as GD32F303 or GD32F4XXX?

The It’s been a journey but I have had success.
I used Web Builder to download a firmware.bin file for a STM32F1xx using the board CNC 3040 F103RC with 4 axes and ganged motors on Y drive.
I had a ST—Link which I tried to use to download the firmware to a board with a GD32F303CCT6 MCU. It failed with a write error. I had multiple tries but same results.
I bought a GD-Link from Aliexpress and downloaded all the GD software but all the software failed to recognise it as a GD-Link so it wouldn’t connect to the board so I sent it back.
I then bought a PWLINK2 ( not the lite version) and downloaded PowerWriter software to go with it.
It downloaded the firmware.bin file to the MCU then I opened gSender and it recognised the board as GRBLHal and connected and, while I haven’t run it on an actual CNC machine, it responds to the software and moves the pointer around the screen and recognises a 4th axis.
One thing to note; if you close gSender down without pressing “ disconnect” it can fail to connect next time so you have to unplug the USB cable, reconnect and it connects fine. If you disconnect within the software, it’s fine.
Hope that helps
One quick note. After downloading the firmware, and before disconnecting from the PWLINK, press the NRST button on the board.

@lappa1 Thank you for your reply, friend. Have you tried compiling your own project to run on a GD chip?

I’ve only written very basic sketches in ArduinoIDE using the STM32F103 as the board then processed as a . Bin file. These seem to load with both the ST- Link and PWlink2 and work fine.
I have downloaded the GD32EmbeddedBuilder v1.5.7_rel but haven’t tried it yet. I’ve tried basic LED blink sketches using STM32CubeProgrammer which seem to work fine on the GD board.
Yet to try anything complex.
