I am new to STM IDE.
I am using STM32 Cubemx with SIMCOM 7600C1. The code is in attachment.

I dont know what is happening but throwing following error:



Multiple errors reported.

 

1) Failed to execute MI command:

-var-create - * rx_buffer

Error message from debugger back end:

2) Unable to create variable object

 

3) Failed to execute MI command:

4) Failed to execute MI command:

Which STM32 MCU are using? Are you using a STM32 board?

Which STM32CubeIDE version are you using?

Ensure that the variable rx_buffer is properly declared and initialized in your code.
