问题 I have a ChibiOS 3.x program on a STM32F4 microcontroller where I use the IWDG watchdog to reset the MCU on errors like this: int main() { iwdgInit(); iwdgStart(&IWDGD, &wd_cfg); while(true) { // ... do stuff } } If I now attach my debugger and, at any point, stop the program (manually or via a breakpoint), the microcontroller will reset after the timeout defined by the watchdog configuration (and therefore cause issues in my debugging process) How can I disable this behaviour, i.e. how can I

问题 I have a ChibiOS application where I'm using dynamic memory allocation via malloc() . However, I observed that 100% of the time I call malloc() , it returns NULL . I have confirmed that: The microcontroller memory is not full The error also occurs for size-1 malloc calls, so the memory chunk size is not the cause of the issues. errno is always ENOMEM after the malloc() call How can I resolve this issue? 回答1: When you look at the definition of _sbrk in os/various/syscalls.c , you can clearly
