About STM32WL55

[Son, Dong-Seong]

Hi

I am testing SUBGHZ with STM32WL55

I activated IPCC of System Core and SUBGHZ of Connectivity.

and then I enabled SUBGHZ_PHY of Middleware and Software Packs

​

I generated code and compiled.

When I run the program, it halted.

​

It enter the Error_Handler in the if statement ( if (OptionsBytesStruct.IPCCdataBufAddr != (uint32_t) pMb_RefTable) ) of the MBMUXIF_SystemInit function.

​

​I don't know why.

Can you explain why the program go into Error_Handler.

and can you tell me how to make the program work normally?

​

I attach the ioc file.​

Hello @Son, Dong-Seong​ ,

I advise you to start with an available SubGHz_Phy_PingPong_DualCore example in the STM32CubeWL package.

In this example, IPCC and MBMUX are used for multicore communication.

So, when you configurated your project, try to get inspired from the instructions in the readme file and the .ioc example file.

I hope this help you to solve the issue!
