so im trying to upload a firmware into an DevEbox STM32H7XX i tried so by following the [Setting up the Build Environment (Linux/Ubuntu)] (Setting up the Build Environment (Linux/Ubuntu) — Dev documentation) after i ./waf configure --board=DevEBoxH7v2, ./waf plane, and then ./waf plane --upload and it detects the board it says at the end this error.
how do i try to reduce the size of the firmware image or is there any other fixes for this error?
