I cannot enter boot mode with my BlackPill F411 board anymore. It's currently running one my sketch successfully uploaded few weeks ago but now, I don't know what's happen.
I've read this post which unfortunately doesn't help me.
Blue led doesn't blink, CubeProgrammer 2.14 doesn't detect any DFU mode and Arduino says
-------------------------------------------------------------------
STM32CubeProgrammer v2.14.0
-------------------------------------------------------------------
Error: Target device not found
Establishing connection with the device failed
Failed uploading: uploading error: exit status 1
I try to upload via USB here is my setting:
Get_PnpDevice says in PowerShell: "BLACKPILL_F401CC CDC in FS Mode".
Isn't it strange? So do you have any idea please?
I use STM32 MCU based boards 2.6.0, IDE 2.1.1. don't know if it occured after some release.
