How to debug a HardFault on an ARM Cortex-M MCU | Interrupt
Nov 20, 2019 · Upon exception entry some registers will always be automatically saved on the stack. Depending on whether or not an FPU is in use, either a basic or extended stack frame will be pushed by hardware.. Regardless, the hardware will always push the same core set of registers to the very top of the stack which was active prior to entering the exception. ARM Cortex-M …

microcontroller - Running code from RAM and not using
$begingroup$ If you are running bare metal then you would use the entire RAM, SAM-BA lives in ROM and tries to move code from your flash to the first few blocks of RAM and then hooks into your OS or secondary bootloader, you are trying to use it to start a baremetal application, the simplest case is to burn it to the entire ram and execute a

Nov 10, 2015 · Running code from RAM is not an automatic performance improvement. Not all devices can fetch code and data from RAM simultaneously, and instead have to insert extra wait cycles. In my note about running from RAM in the LPC4370, is stated "carefully selected RAM segment" for precisely this reason.

Creating a Second-Level Bootloader for FLASH Bootloading
booting, the load image consists of sections of code and initialized data. Determination of the run address of a section is based on how frequently the CPU accesses that particular section. If a section is accessed only once by the CPU then typically it will not have a run address in RAM. This will save RAM space for other purposes.

What are the possible boot modes in the S32K146 (NXP S32K
Nov 16, 2018 · So it is possible, for instance, to have a bootloader that loads an application from an external memory into the MCU's RAM, and then execute the application from RAM. This capability is sometimes exploited by debug tools, which can write a small application into RAM to do things like load data into an external flash memory.
