i've modified the STMduino bootloader to work on my custom board, now i flash the uc using USB cables, but is there any snippets of how i can access the I2C inside the bootloader to be able to read the firmware data from an EEPROM connected to my I2C and flash it as if the data was over usb ?
My processor STM32F103R8Tx
Firmware Development: using HAL
Generic boards that are not Maple or Maple mini clones, and don't contain the additional USB reset hardware
