Moved from arm-none-eabi-gcc 8.2.1-1.7 to 9.2.1-1.1

[fpistm]

Thanks to @ilg-ul, arm-none-eabi-gcc packages are now available from:
https://github.com/xpack-dev-tools/arm-none-eabi-gcc-xpack
Release v9.2.1-1.1

Linked:
stm32duino/arm-none-eabi-gcc#2

Great! Please don't forget to also update https://github.com/stm32duino/arm-none-eabi-gcc/blob/master/README.md, and generally to replace all references from GNU MCU Eclipse to the new xPack names.

Done also in the README.md of the core 😉

Great, thank you!

Generally when you mention the project prefer the web url:

Yes this is the one used as link when I wtrote : The xPack GNU Arm Embedded GCC 😉

Ah, right, I saw only the following GitHub URL.

Attached the full build log using the new xpack-arm-none-eabi-gcc-9.2.1-1.1.

Only one fix applied to Firmata:

Does this mean that your tests passed with the new GCC 9.x?

At least all builds are passed. For the tests, I currently have no issue but I do not finished them for the next release.

I am using Arduino IDE v1.8.10 with v1.7.0 of the Core under Windows 10 x64 (VM) for testing changes all updates to the Core code. For this change, I have not been able to get the gcc 9.2.1-1.1 to compile successfully and I suspect it is related to where I put the gcc compiler code. I tried putting in the xPack directory as suggested but I get:

exec: "/bin/arm-none-eabi-g++": file does not exist
Error compiling for board Generic STM32F1 series.

I have not included this path in the Windows path. Should I? I am not sure how the Arduino IDE finds the necessary toolchain. Any suggestions or do I need to wait for v1.8.0 of the Core to be released which I assume will include the updated gcc toolchain.

if by 'as suggested' you mean where the xPack documentation suggested (https://xpack.github.io/arm-none-eabi-gcc/install/), then Arduino will not find it, because the Arduino IDE is not xPack aware, only the Eclipse MCU plug-ins are able to identify them there and automatically adjust the path.

[pkourany]

So where should I put the gcc toolchain files for the Arduino IDE to find them?

@pkourany
while the 1.8.0 is not officially release, you can install all dependencies thanks the JSON available in the dev branch:
https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json

Other method is to simply download the package from :
https://github.com/xpack-dev-tools/arm-none-eabi-gcc-xpack/releases/v9.2.1-1.1/

then unpack it in the Arduino package folder, anyway you will have to do some manual update like Arduino does:
When you extract, you will have this:
STM32/tools/xpack-arm-none-eabi-gcc-9.2.1-1.1/
But Arduino split the name and the version like this:
STM32/tools/xpack-arm-none-eabi-gcc/9.2.1-1.1/

To find the Arduino package folder:
https://github.com/stm32duino/wiki/wiki/Where-are-sources

Thanks for the PERFECT instructions! I move the gcc to the suggested path and now everything compiles as expect. Thanks again.
