• Random Hardfaults on a cortex-M7 microcontroller
    Hello, I am facing random HardFaults on a cortex-M7 based microcontroller (STM32F722). They happen at various places in code, sometimes even during stack's initialization. Stack's analysis do not...
  • Cortex M4: Atomic and Cache
    Hello all, Recently I came across this issue for the cortex M4 core. We are running a freertos application which loads and stores the value of a variable. For this we are using the atomic functions...

    hi, im a total noob here so do excuse if im asking some weird question. im using an arm cortex m4f for the first time ... i looked online and i was able to find the TRM for the arm cortex m4f. however...
  • Unidentified hardfault on Arm Cortex-M4
    I have a whole bunch of hardfault annotations - all of them show CFSR value as 0. I've tested the annotation mechanism with two intentional hardfaults (divide by zero and write through null pointer) and...
  • Cortex M4 - Returning from Interrupt
    Hi, I'm using the STM32 F407 (Cortex M4), and I am also only using assembly in uVision IDE. So far I have managed to setup a ISR for a pushbutton generated interrupt via GPIO. This all works, I get...
