Hello,

Maybe here you will find some useful info

CCM RAM usage, Mbed linker magic

I have a mbed app with a webserver, running on a F407VE with 128 kB RAM + 64 kB CCM RAM, this works fine and I have some free RAM. Now I have moved the same app to another custom hardware with also F407VG and same RAM settings, but now my app crashes after trying to allocate some dynamic memory with ‘out of memory’ exception. I have compared the linker scripts, but the settings are almost the same between F407 VE and VG MCU. The VE has only the addion for MBED_APP_START, but this makes no diff…

BR, Jan
