Arduino for STM32

1. Flash https://github.com/rogerclarkmelbourne/STM32duino-bootloader/blob/master/binaries/generic_boot20_pc13.bin. I flashed using ST-Link, BOOT0 -0, BOOT1 -0 2. Then flash it through Arduino, only using Maple DFU Bootloader 2.0 . If after step 1 you flash it using ST-Link, then Maple DFU Bootloade...

Yes, if you specify the Arduino settings correctly and upload the Roger bootloader, it works. But not on all boards. At some point, Serial is there, but does not want to be attached, the bootloader breaks

It's strange, with stm32f103C8 64k, Serial did not work, but with stm32f103C8 128k, it worked. How can you flash using USB? As I understand it, there is a substitution of concepts. Roger does not have a bootloader, this is an addition to his kernel. Is there a bootloader that could be used to flash ...

ST-Link is there, the question is that people flash the bootloader, after which a UART appears on the USB and you can flash the STM using the UART

Hello, I just can’t figure it out, I want to load the firmware into stm32f103 via usb, and also have serial on the same usb.
Which bootloader should I use?

It can't work... Datasheet is almost always helpful: https://www.st.com/resource/en/datasheet/stm32f103c6.pdf First page: – 1 x I2C interface (SMBus/PMBus) I made a big mistake. I painted the functionality of the controller for myself based on the picture, but there was no difference between the su...

Hello Can't use i2c on PB10, PB11 board stm32f103c6. The scanner example works on other pins, but not on i2c2. Please help, am I doing something wrong or is this a bug? // -------------------------------------- // i2c_scanner // // Version 1 // This program (or code that looks like it) // can be fou...
