Dear Seeed support (the forum is called Tech Support - I’ve not invented it!?!). I honestly spent most of my night trying to program the new MCU. My latest result - I manged to download a *.bin extracted from *.dfu taken from package STM32_USB-FS-Device_Lib_V3.3.0 through UART connector on the main board. That connector said to be the only available bootloader in STM32F103 (I read STM manuals). Now when connected the body is detected by Windows as ST Microelectronics Virtual Com Port. I don’t know why I did this - probably because nothing else works. If I try anything else, the device cannot be identified. Please let me know how to make it back to my DSO from scratch. Thanks in advance… I’m just begging for some mercy here I gues…
