Issue with Installing and Uploading to Blue Pill

[safi_huss]

I am a newbie here so I must be doing something wrong here.

I installed the bootloader (generic_boot20_pc13.bin) and installed the boards on ArduinoIDE, copied the Arduino_STM32 folder and ran the install_driver.bat file.

After the first code upload the blue pill since flashing with the bootloader. I get the following output in my IDE.

Code: Select all

Sketch uses 9968 bytes (7%) of program storage space. Maximum is 131072 bytes.
Global variables use 844 bytes (4%) of dynamic memory, leaving 19636 bytes for local variables. Maximum is 20480 bytes.

The blue pill is running the sketch though, but all subsequent uploads fail with the following:

timeout waiting for COM3 serial

I also checked the device manager and the COM3 port which was available before the first upload is missing. There is also an Unknown USB device.

I don't know what I did wrong. Please help.

In order the automatic reset (to DFU serial) to work you have to upload a sketch in which you use serial USB.
Otherwise you have to set BOOT 1 to high and reset the board each time before next upload. Then set BOOT1 back to low and reset.

Sometimes when it not found the dfu device, its because whe upload is triggered and DFU mode activated with vid 0003 , reset its fast enough or to fast to not see the change..
Im collected a couple a scripts to detects the timing and then change it. Its in a git repo...
For myself reduces the problem to zero, its usefull for forgetting to press the reset button of bluepill...
