Error: Cannot write file D:\\main.py. Disk full?!

Hi

I’ trying to save the script in the OpenMV cam and read the data via serial port. But when i try Tools → Save open script to OpenMV cam → I’m getting a error “Error:Cannot write file D:\main.py. Disk full?!”

I’m not using any uSD card. Should I use any to save the script?

Hi, can you verify the D drive is writable and is the OpenMV Cam’s uPy flash drive?
