I want to configure and boot the Linux kernel on a Cortex m7 microcontroller. In this case I'm using stm32H743 development board with on board DRAM. please guide me how to boot Linux on this board.
I'm completely new to operating system world. but I have years of experience in C++ bare metal development.
I read on the internet that I should use a boot loader like BareBox or Das U-Boot. but they don't support my microcontroller. Also, the Linux kernel won't support STM32H743. how I can add this hardware support to the Linux kernel and BareBox bootloader?
I know all hardware registers of STM32H7. but I don't have enough information about Linux kernel and BareBox or U-Boot bootloaders.
NOTE: I want to use the Linus Torvalds Linux repository. (Not the EMCRAFT uCLinux)
