I have a Flash Full test failed issue with the STM32F427 ClassB library V4.0.0 code in Keil project.The project is generated from the STM32F446RE-Nucleo examples. Attached please find my scatter file and the post-build command batch file. (I have tested the official CubeIDE project and it can pass the Flash Full test and also the runtime partial flash test.)
