MIOS Studio bootloader timeout

Testing/Troubleshooting

Hello,

While trying to upload a new firmware to my STM32F4 core,  MIOS Studio timed out trying to enable the bootloader mode.   How can I repair this?

Can you get back to the bootloader by pressing (and holding) the blue button?

Bootloader mode is enforced as long as the blue button is down. 

I got confused about this a little while ago; you can then upload the bootloader hex file, thereafter you don’t need to hold the button any more. 

Now you have a stable USB-MIDI connection and you can upload your application of choice. I’m not sure if re-uploading the bootloader hex is actually needed…? but it can’t hurt.

Yes, got it.  Switch the box off, keep the blue button pressed, switch on, start Mios studio and it connects in boot loader mode. And then, it uploads the firmware without any issues.  

Thanks @Latigid On!

because of programming and messing arround, i have to press that button every programming session often…

so you better wire a switch to the back off your device… Pin  PA0 to 5V on the STM32F4 do the job… (the programming switch)

yes I was thinking about that as well. Thanks for telling me the pinning!
