STM32CubeIDE version 1.8.0
STM32CubeMX version 6.4.0
Board -> NUCLEO-F429ZI (Nucleo 144)

I am porting X-cube-cellular version 7.0.0 to the STM32F4 platform. My code compiles and runs but the call to MemInit () in osKernelIntialize() fails when it calls tx_byte_pool_create().

I created my project using CubeMX and set it up for Azure RTOS F4 Software package. I have kept the NetX and TX defines the same as the X-Cube-cellular project (B-L462E-CELL1->Nx_TCP_Echo_Client_PPP). I have attached my complete project below. I'm sure this has something do with CubeMX configuration and using the abstraction layer but I have no idea where to start debugging. Any help is very appreciated! Thanks

From further debugging I have discovered the following:

MemInit() fails because
tx_byte_pool_create() is returning TX_PTR_ERROR because
_txe_byte_pool_create() argument VOID* pool_start is NULL

pool_start is set to _tx_initialize_unused_memory which is NULL.

I found I forgot to initialize a place in Flash linker script for the threadx stack. You also have to turn on the dynamic memory allocation #define in the tx_initialize_low_level.s file
