Linux kernel: Change DRAM address to 0x0c000000 and size to 0x01000000.Latest stable Uboot 2104 config for ARM Cortex M7 to boot from internal flash Latest (as of 1st July 2021), Linux Kernel 5.13 Keypoints This is a short documentation about my findings on building uboot, Linux kernel and root file systems for the STM32F769i discovery board. Comparing them with recent MCU like ARM Cortex M, the M4/M7 has so much more processing power and the ability to access much more memory resources. I used to work with 8051/2 and Microchip PIC18/24.
