Hello everyone,
Newbie to the whole stm environment here but am trying to learn. I'm developing on the NUCLEO-WL55JC1.
I've been trying to create a dual core communication design using IPCC. I started with loading the "IPCC_HalfDuplexMode_DualCore" example available in the STM32CubeWL firmware package -- which worked just fine. Moving forward, I created a new project using CubeMX from the IOC file in the example so I could develop further using that as a base. However, I keep getting this error:
'IPCC_C2_RX_C2_TX_IRQn' undeclared (first use in this function); did you mean 'IPCC_C1_TX_IRQn'? stm32wlxx_hal_msp.c /DualCoreComm_LVL1_CM0PLUS/Core/Src line 92 C/C++ Problem
The problem originates in the "stm32wlxx_hal_msp.c" file in the "HAL_IPCC_MspInit" and "...DeInit" functions at the "HAL_NVIC_SetPriority()" and "...DisableIRQ" function calls.
Of course, the first thing I did was check if the IRQn type "IPCC_C2_RX_C2_TX_IRQn" was declared for CM0. As far as I can tell, it is in the "stm32wl55xx.h" but it is under a "#if defined(CORE_CM0PLUS)" condition and so, I went into my main.h file for CM0 and defined CORE_CM0PLUS there just to see. That took the error away and I could load both cores but the IPCC did NOT work.
I then tried to just replace the "..Init" and "...DeInit" functions in CM0 with the ones CM4 uses to just follow the suggestion from the compiler which also loaded just fine but did NOT work. At this point, I'm lost in so many header and source files I don't really know what's up and down anymore.
In "stm32wlxx_hal_ipcc.h" all of the defines, variables, and function declarations are under a "#if defined(IPCC)" but are "crossed" out in the outline window as if they aren't initialized properly. But, IPCC also seems to be defined in "stm32wl55xx.h".
I've tried cross checking all (maybe i missed some?) the files used by the example and what my project has available but see no relevant differences. What am I missing here, am I an *** (likely)? Please help. Thank you
