CmBacktrace | Advanced fault backtrace library for ARM Cortex

CmBacktrace is a C library. CmBacktrace has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

firmware name, which must correspond to the firmware name generated by the compiler. The hardware version number corresponding to the firmware. Software version number of the firmware. Note: The above input parameters will be output in case of assertion or failure, mainly for retrospective purposes. Note: The input parameter SP should be obtained inside the assertion function as much as possible, and as close as possible to the beginning of the assertion function. When used in the sub-function of the assertion function (for example: in the assertion hook method of RT-Thread), due to the nesting of the function, there will be the operation of registering the stack, and the SP will be changed at this time, and manual adjustment is required ( Add and subtract a fixed deviation value) into the parameter value, so as a novice, it is not recommended to use this function in the sub-function of the assertion. This function can be called in the fault handling function (for example: HardFault_Handler). In addition, the library itself provides assembly files processed by HardFault (click to view, you need to choose according to your own compiler), The cm_backtrace_fault method is automatically called in the event of a fault. So when transplanting, the easiest way is to use the assembly file directly.
