Arm Cortex M4 Memory Map

The role of the locator is to assign specific address locations to the object file according to the memory map of the microcontroller After performing address allocation, the locator produces an executable file that we can install on the target embedded device data and bss section are copied to RAM memory of ARM Cortex M4.

Arm cortex m4 memory map. CortexM0, CortexM3 and CortexM4 processors by default the vector table is located in the starting of the memory map (address 0x0) In CortexM7, CortexM23 and CortexM33 processors the default value for VTOR is defined by chip designers. 212 Cortex Memory Map (pag 190) 213 CortexM4 Memory Map (pag 192) 52 Special notes about I2C demos Since we have no onboard sensors, under "driver_examples/i2c_imx" you will find 2 demos accessing the RTC The demos require disabling I2C2 from Linux dts This also means that both WM8731 and OV5640 cannot be controlled on Linux side.

The CortexM architecture specifies a fixed memory map and a small set of standard peripherals, including a vectored interrupt controller and a system timer This encourages a high degree of standardization across vendors, tools and operating systems, building a strong ecosystem around standard parts from multiple sources. Due to its fixed memory map, the code area starts from address 0x (accessed through the ICode/DCode buses) while the data area (SRAM) starts from address 0x (accessed through system bus) The CortexM4 with FPU CPU always fetches the reset vector on the ICode bus, which implies to have the boot space available only in code area. Please find the below image to know about the Memory map of ARM CortexM4 Here, we have a code region, where we are going to write our final binary That memory is starting from 0x to 0x1FFFFFFF Now we will forget about other regions.

From the Github project page, libopencm3 is an Open source ARM CortexM microcontroller library, which supports a large number of microcontrollers The main advantage here is that the API is the same for all supported MCU families, so there is a way to extract all the vector tables from a single source Retrieving the base memory addresses. The Memory Protection Unit (MPU) dialog shows the MPU Control Register and the memory map of the MPU, the number of regions with the location, size, access permissions, and memory attributes of each region The following applies to an MPU the default memory map can be configured to provide a background region for privileged accesses the MPU divides the memory into regions.
