When was the last time I worked with STM32F4?
Last time I worked with STM32F4 I used a different toolchain that you’re using, but I was constantly getting stuck in the HardFault because of compiler issues, then a memory management issue from a library I was using, then also just because I wrote dumb code (as we all do occasionally).
How to generate STM32 code in truestudio?
I use STM32CubeMX V 5.1.0 and TrueSTUDIO Version: 9.3.0 (Build id: 20190212-0734). I’m uploading a photo of the steps I followed to generate the code via STM32CubeMX. My program consists of only UART code (USART1) which I set up on CubeMX as picture shows. Nothing else. And this is the code of main.c
How to program a stm32f412rg hardfault handler?
I’ve been trying to program an STM32F412RG but my program is stucked at HardFault_Handler once debug starts. My board is an Wio LTE EU Version and I’m trying to program it using a nucleo board as an external debugger/programmer.
Where does the break point occur in STM32?
See the following screenshot: The breakpoint happens inside the stm32f1xx_hal_i2c, in this code (==> is break point): This function is called from within many functions inside the same file.
How does the hardfault handler in STM32 work?
Eventually, two functions are called, gn_resids and gn_jacobian. The functions are very similar in structure. Both take in 3 pointers to 3 arrays of floats and then modify the values of the first array based on the second two. Unfortunately, when the second function gn_jacobian exits, I get the HardFault.
How does memcpy cause hardfault on STM32F4?
Or pPacket + size points out of memory. when I run this code the programm hangs when I stop the uC with JTAG I see it is in infinite loop of hardfault handler memcpy somehow causes hardfault I think above memcpy is ok – how much simpler can it be ? it must be something wrong with the gcc please how can I proceed ? linkerscript?
