I am unable to flash my board with Luos bootloader, when using ST-Link connected gate

Symptom(s)

When you try to update a Luos board using the bootloader in a network connected with your computer using ST-Link, the process fails during the last step of flashing.

Possible explanation

This may be a bug from the ST-Link driver occuring with a specific size of messages, and so a specific size of binary files.

Resolution

Try to connect your gate to your computer using another protocol, like FTDI, and flash again. If it doesn't work, try to resize the .bin file you want to flash, by slightly changing your application's code.
