SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.

Unknown Type Name error


Hi Tim,

Is it possible that, directly or indirectly, usbh_def.h includes usbh_MIDI.h before defining USBH_ClassTypeDef, or usbh_core.h includes usbh_MIDI.h (again possibly indirectly) before including usbh_def.h ?

This kind of problem usually comes from incorrect cross-references between header files: as they are all protected by a “single include #ifdef” when an included file tries to include the file that includes it, this does nothing so only the definitions located before the recursive inclusion are visible...

Hope this helps,

Bernard (Ac6)

PS: You could try to add the -E flag to your compile line: instead of compiling your file, it will generate the preprocessed source code, with all includes “flattened” so you should understand why it does not work as expected.
