If your device does not go in bootloader mode, you can get the COM port by moving the jumper BOOT 1 in the HIGH position (1) and reset. After that, the led starts to blink, and you have this Serial output. | HID-Flash v2.2.1 - STM32 HID Bootloader Flash Tool |Īnd finally, you have the COM port named “STM Serial”.
To upload the bootloader, we must put the device in “System Memory”.Īn error occurred while uploading the sketchĬ:\Users\renzo\AppData\Local\Arduino15\packages\STMicroelectronics\tools\STM32Tools\2.1.1/win/hid-flash.exe C:\Users\renzo\AppData\Local\Temp\arduino_build_278975/ COM28 Upload HID bootloader with STM32CubeProgrammer Here is the table with jumper configuration: BOOT0 This isn’t often used, usually, you’re doing something tricky like a temporary bootloader or the like. You can load flash via JTAG, the on-chip bootloader (above), etc. In normal operation, your code will reside in flash, and on Power-On Reset (POR), the CPU will fetch the reset vector and initial stack pointer (SP) from flash.
This allows you to load (program) code into the device from an external interface such as UART or USB. The driver installation simply fails because of the certificate issues on the backend. Because of this, ZADIG does not seem to work when trying to update the STM32 BOOTLOADER device with the WebUSB driver. Boot from System Memory: that invokes the on-chip bootloader, which is present in the chip directly from the factory before you’ve programmed anything into the on-chip flash. And it seems that MSFT has made it a LOT harder to get past the security it put in place for drivers.
