STM32F103C8 SysTick initialisation issue
Hi,
I am using STM32F103C8T6 Blue pill board, STM32 CubeIDE 1.16.0, Build: 21983_20240628_1741 (UTC) on Ubuntu 22.04.5 LTS and ST Link v2 debugger. I am able to upload code, execute it and debug it via SWD.
I am using CubeIDE's Pinout & configuration utility to configure peripherals and software modules. I want to add FreeRTOS to an empty project. Due to issue 189410 I have to revert Firmware package version to 1.8.5. If I select Firmware package version 1.8.5, I can enable FreeRTOS with CMSIS_V2 interface and generate and compile code successfully. For FreeRTOS to work, I enable USE_NEWLIB_REENTRANT in FreeRTOS advanced configuration tab, and also select a timer as Timebase source in SYS module. I tried selecting TIM1, 2, 3, 4 - all of them produce the same result. In RCC module I selected Crystal/Ceramic Resonator as HSE, in Clock Configuration I used default 8MHz as HCLK.
If I try to run the generated code, execution halts in __NVIC_EnableIRQ() when SysTick Timer interrupt gets enabled. I attached call stack below.
I run into the same issue even without FreeRTOS, if I select any timer as Timebase source in SYS module.
Am I missing something in my RTOS or peripheral configuration? Could it be a hardware issue? I don't have another F103 at hand to test it with another MCU, so I can't rule it out.
Best regards,
Akos
