Hello All, Good Morning! I am working on Cortex m4. I have read following about hard fault , "Bus Fault: detects memory access errors on instruction fetch, data read/write, interrupt vector fetch, and register stacking (save/restore) on interrupt (entry/exit)
The DSP instructions and the optional floating-point unit improve the performance of numerical algorithms and enable signal processing operations directly on the Cortex-M4, Cortex-M33, and Cortex-M7 processors, while maintaining the ease of use of the Cortex-M programmer’s model.
The rate of value decrement depends on the system clock frequency and we can set the value of clock frequency using a control register which is associated with the Systick timer. All XMC4000 devices are powered by Arm® Cortex®-M4 with a built-in DSP instruction set. The Single Precision Floating Point Unit, Direct Memory Access (DMA) feature and Memory Protection Unit (MPU) are state-of-the-art for all devices – even the smallest XMC4000 runs with up to 80MHz in core and peripherals. ARM Cortex-M est une famille de processeur RISC 32-bits d'architecture ARM servant à la fois de microprocesseur et de microcontrôleur à destination de l'embarqué. Elle implémente d'abord le jeu d'instructions ARMv6-M (Cortex-M0, Cortex-M0+ et Cortex-M1) puis le ARMv7-M (Cortex-M3, Cortex-M4 et Cortex-M7) [ 1 ] . 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.

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 the ISR handler hit, but after I perform my ISR function how do I return back to thread mode, and set the PC back to last point of execution ?
