I'd like to avoid installing Rosetta too, is there any plans to support this @ptillisch ?

The GitHub issues that you linked have no activity on them, and as others have said, Apple has not committed to Rosetta as a permanent feature of macOS...

23

I don't have any information to share regarding any such plans. That is the domain of the project managers.

The best path forward is to make sure that the request is being tracked by an issue in each of the relevant GitHub repositories. This will make it more likely for the project manager to give it consideration when allocating development resources.

The essential thing to understand is that, with the exception of the Ctags tool which is used universally, the remaining work is in producing native Apple Silicon builds of the toolchains. Each board may have a different toolchain, and some of those tools are provided by 3rd parties. So you need to identify the toolchain of the specific boards you want to work with and then check to see if a request has already been made for each of those tools.

:red_exclamation_mark: Please check to see if there is already an issue before submitting a new request to avoid creating duplicates.

24

I’ve tried to understand where the problem could be but I did not get a consistent result so far. I believe that the problem of the board not erased is due to an incorrect flash base address somewhere. The Nano Matter board is correctly flashed (erase and loaded) using Arduino IDE on Mac Intel while does not get flashed with Mac arm64 (apple M4).

Hereunder the two logs from Arduino IDE

As you can see there is no error but only a warn . I have searched for this message and found it in efm32s2.c where there is a long list of CPU Family data. Here to follow the first lines:

static const struct efm32_family_data efm32_families[] = {
                { 16, "EFR32MG1P Mighty", .series = 1 },
                { 17, "EFR32MG1B Mighty", .series = 1 },
                { 18, "EFR32MG1V Mighty", .series = 1 },
                { 19, "EFR32BG1P Blue", .series = 1 },
                { 20, "EFR32BG1B Blue", .series = 1 },
                { 21, "EFR32BG1V Blue", .series = 1 },
                { 25, "EFR32FG1P Flex", .series = 1 },
                { 26, "EFR32FG1B Flex", .series = 1 },
                { 27, "EFR32FG1V Flex", .series = 1 },
                { 28, "EFR32MG2P Mighty", .series = 1 },
                { 29, "EFR32MG2B Mighty", .series = 1 },
                { 30, "EFR32MG2V Mighty", .series = 1 },
                { 31, "EFR32BG12P Blue", .series = 1 },
                { 32, "EFR32BG12B Blue", .series = 1 },
                { 33, "EFR32BG12V Blue", .series = 1 },

You can see from the flash output (both platforms) that the family number is 24 but for some reason it is resolved on Mac INTEL and not on Mac M4. On this last platform the warning suggests that it is defaulting to G22 values.
Any suggestion is appreciated

I have deleted your other cross-post @new4fun.

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting can result in a suspension from the forum.

In the future, please only create one topic for each distinct subject matter. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

In order to make relevant information available to any who are interested in this subject, I'll share a link to these related GitHub issues (I guess those were created by you @new4fun?):

Yes , they are mine .
