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
1. Introduction In previous articles, we introduced some basic principles of SDRAM. This article will introduce the SDRAM controller under the FMC of STM32F429. 2. Introduction to the SDRAM Controller of STM32F429 According to the general module driver initialization process, it mainly involves the clock path: clock source to clock division configuration, enabling clocks for … Read more
Introduction — In FPGA-based image acquisition and display systems, large-capacity and high-speed memory is often required. Among various random access memory devices, SDRAM is an ideal choice due to its low cost, small size, high speed, and large capacity. However, the control logic of SDRAM is quite complex, and the timing requirements are very strict, … Read more
