Has anyone tried EFM32? https://www.silabs.com/mcu/32-bit . I set on stm32 because I'm familiar with ChibiOS, but may be it's time to move on or try something new. |

The idea that ARM MCUs are becoming difficult to buy is strange. And if so, it appears a problem of the supply chain rather than of production of a certain brand. And the approach of implementing one design with no variation possible may not be enough in a crisis. At least one should be able to make the product with another member of the same MCU familiy, like in the example above F6P6 instead of F4P6. Better you can have two designs with one MCU from STM and one from Microchip. I think it is great that we can work with a common code base, at least the application part. Regards, Dieter |

Porting code for a serious product say 100-200kloc from uC manufacturer A to manufacturer B even when the core is the same and the compiler is the same can take a team of three SW devs about 6 to 9 months of time depending on the amount of testing you require. My previous company has done this multiple times because of new peripheral features for future features and/or lower price/quantity, but there can be lots of surprises. You would like to already have automated endproduct system testing in place for product verification. |

A pain if you have to do it in a case of emergency. If you plan it from the beginning it may even help to better structure the firmware into system parts that depend on the hardware platform and application parts. Yes, a redundant effort will cause extra cost. But that depends. In an industrial supply chain you may win a contract if you can prove that you have a plan B. In former times they would call it "second source". I remember very well the discussions in March when it turned out that China won't be able to supply protective medical equipment for the whole world, because they needed it themselves. Here in Germany people became nervous and started telling lies about the necessity of masks etc. Later they said they will enforce national supplies in critical sectors of public health. Don't know whether it is ever going to happen. Nobody wants to be second source. Regards, Dieter |

I tested GD32F103C8 - didn't notice any problems. :) |
