Arduino for STM32

Hello, Stombo. I begin to code on STM32F1xx and F4xx without libraries ( barre metal is a funny name !). For STM32F1xx, i've saw, in doc "cd00246267-stm32f100xx-advanced-armbased-32bit-mcus-stmicroelectronics" RM0041 §12.3.7 p233, one answer low level to your question. For STM32F4xx, it' d...

Hello, AndrewBCN. Thank you for your tip. But i've Roger's core, no official core made by STM. And before install official core, i would try one another PC for tests. After, if it's not too heavy, why not ... Is DIYmore STM32F407VGT6 likely familiar with "generic STM32F407V mini-series" na...

Hello.
In the screenshot, we can see a lot of cards of STM32F4xx family, and the black or DIY MORE series !
I'm very interesting to know what is the used core of this picture.
thank you.

Yessssss ! This subject was in actuality five years before ! Thank you, fpiSTM for these links where we can see a good and elegant answer. it's what i expect. Idem ag123 : it's exactly this -> transition between 32 and 64 bits apps isn't easy ! mrburnette : i don't understand what you say about this...

Hello. I've chosen this board for her little size, flash 1MB, CAN bus, FPU and frequency 168MHz ... Flash with Arduino_STM32-master is correct with STLink key and "Generic STM32F407VE series" type of board. Pin's affectation is different than BlackF407VE ( ie in board LED is on PE0), but t...

OK, perhaps it's a good way but it's not resolve the initial problem : why Arduino_STM32-master use linux tools and not linux64 tools ? I've found a bad but simply patch witch work and i don't want to install other specific software on the PS OS to correct an anomaly. For information, STLink key wor...

... step by step ... and it's work now ! In my previous post, i've remarked that Arduino_STM32-master use tools in .../arduino-1.8.13/hardware/Arduino_STM32-master/tools/linux. but these tools don't work on a Linux 64 PC. Good tools are in .../arduino-1.8.13/hardware/Arduino_STM32-master/tools/linux...

Thank you for your help ... and i progress step to step ! I'm always in travell, but i've token some hours for work a little ... I've read all the previous links and install STM32CubeProgrammer ( witch is a nice tool). Nothing better after link nor with STM32CubeProgrammer witch made one alarm Old S...

... error ! it's not STM325F4xx but STM32F4xx where are my bugs !
If you use STLink key with STM32 Arduino IDE, what is the name of the key port which appear ?

OK, ag123. I'll see all of yours links later because i'll travel tomorrow for some days. I'd checked the permanent reset button press when flashing ... but no effect. I've no problem with the Chinese blue pill : USB-serial converter work fine with them. Problems are only when i want use STM325F4xx, ...
