Hi, I’m having issues uploading programs to a Nucleo STM32F303RE.
Both via Keil Studio -

Compiler output:

Connect (‘haltOnConnect’) to device STM32F303RETx…
ERROR: Caught Unknown Exception (RDDI-ERROR 13)

or by drag & dropping the compiled program into the drive via windows explorer:
Error message:
There is not enough space on NODE_F303RE. You need an additional 24.0KB to copy these files.
NODE_F303RE
Space free: 8.00KB
Total Size: 32.0KB
The only visible files in the NODE_F303RE drive are details.txt, fail.txt, and MBED.htm. (total 636 bytes)
The fail.txt reads:
The interface firmware FAILED to reset/halt the target MCU
I’m using the example blinky code, so it’s not a software issue. And I was happily compiling to this board before. So I’m not sure what’s changed.
I sucessfully updated the firmware to the most recent version.
I have a spare board which I can upload to without any issues, so It’s not the cable.
All the jumpers are positioned correctly as far as I can tell (although I have been switching back and forth between U5V power and E5V power during testing. so maybe something’s been shorted out or damaged?
We have also been compiling to this board with both ArduinoIDE, and Keil Studio. So maybe there’s been a build up of data on this device that hasn’t been removed properly?
Is there a way to reformat the memory completely to clear the space? or is there some other cause I’m missing?
Appreciate your help!
