Mastering Linux on MCU Series Part 18: New Boot Design to Load and Start Linux (5) - Loading from SPIFLASH

1. Introduction Previously, we completed the design and source code implementation of the storage layout and loader. Now we will practice and test loading the image from SPIFLASH into SDRAM for execution. Of course, during debugging, we can also directly transfer the image to SDRAM using xmodem for direct execution. See the code at:https://github.com/qinyunti/stm32f429-boot.git Please … Read more
