ESP32 C6 mini compile does not work

[Steve-Matrix]

Thanks, Stefan.

None of the C3 and C6 devices are compiling for me. I'm setting up a completely fresh install on another PC to test further because the toolchain installation on my PC may not be clean.

I've managed to get Flowcode compiling the C3 and C6 devices now.

To do this, I uninstalled the ESP toolchain installation and installed the v5.3.5 offline version from the Espressif website.

I also had to edit the two ESP batch files in %PROGRAMDATA% to point at v5.3.5 instead of v5.3.1 and I had to tell Flowcode where the new ESP toolchain was located.

[EDIT: it was a bit more complicated that just this. But I have a simpler solution now - see later in this forum thread]

Hi Steve

just this file and this line?

Yes, those are the lines that needs to be changed. But note that I do not have any of those devices and so I've only been able to check that they compile ok.

[EDIT: see my next message for a much simpler solution that avoids changing anything in Flowcode]

I have revisited this today and found a neater solution for those Flowcode users who do not want to make the changes necessary to work with the Espressif installation.

For this method, install the Flowcode ESP installer from our downloads page as usual. Some additional files will need to be downloaded and manually added to the toolchain. Other than that, the procedure should involve no edits to Flowcode's batch files or the Flowcode environment.

To add support for the C3 and C6 devices, download the file below and unzip it into the following folder:

Code: Select all

C:\FC_ESP\esp-tools\tools\riscv32-esp-elf\esp-13.2.0_20240530\riscv32-esp-elf\

(assuming the Flowcode ESP32 installation was installed to the default folder).

The file can be downloaded via the link below. It is large (282 MB) and so it is recommended that you only add these files if you require support for the C3 and C6 families.

(EDIT: this download has been removed. Please install the ESP32 toolchain from the downloads page on this site as explained later in this forum thread)

Note the exact path above because there will be several "riscv32-esp-elf" folders once the files have been unzipped. The following image highlights the added folders and shows their location in the folder tree:

When we have the opportunity, we intend to update the ESP32 toolchain installer so that this additional step is not required in future.

That download link in my case only takes to the main flowcode page. I don't see a zip file anywhere?

Login to your Flowcode account, then try the link again

There is now a new ESP32 toolchain MSI download which includes support for C3 and C6 without requiring the fix suggested earlier in this thread. This is available via the download page on this site.

If you previously installed the toolchain from this site, you will receive the error "Another version of this product is already installed" when you double-click to run the MSI download. If you do, remove that previous install via "Add/Remove Programs" and then run the downloaded MSI file again.
