When trying to setup MBedTLS through CubeMX for the NUCLEO-H755ZI-Q, CubeMX does not give the option to select LWIP as the TCP/IP stack in the MBEDTLS "Version and modes" configuration tab. The only options given are "None" and "User defined". Additionally, for the "RNG dependency", the only options are "SW RNG(no entropy)" and "Custom RNG(Custom entropy)". It does not detect that I have enabled hardware level RNG. If I try setting up a project for NUCLEO-H745ZI-Q, I have the same issue. I tried setting up the project so the Ethernet stack was on the M7 only, the M4 only, and both the M7 and M4 and none of these variations made a difference.
However, if I try setting up a project for any single core F4 or H7 variant, like the NUCLEO-H753ZI, I am able to select LWIP and HW RNG(ST entropy). In fact, when I enable MbedTLS, they are auto selected. Please see the attached screenshots.
This is the order always followed:
- Enable Ethernet RMII
- Enable RNG
- Enable FreeRTOS
- Enable LWIP
- Enable MBEDTLS
So it seems that MBEDTLS configuration for dual core MCUs with CubeMX does not work correctly or I am missing a step.
