Author | Wanli Produced by | Automotive Electronics and Software 1. BOOT Source Have you ever encountered a scenario where a new software installation on your computer prompts you to Reboot? Here, Reboot is commonly understood as restarting, while Boot means to start up. But have you ever wondered why the term for computer startup … Read more
Generally, ROM is used to store firmware, while RAM is used to hold data. Since FLASH ROM has faster read and write speeds and is easier to erase compared to ordinary ROM, it is typically used to store user programs and data that need to be permanently saved. For example, the core of a household … Read more
This article aims to validate the usage of the STM32 SPI interface using the W25Q16 storage chip. ●About Flash Chips 1. When writing to flash, it can only change from 1 to 0; during erasure, all bits become 1. 2. The minimum write unit for flash is a page; individual bytes cannot be written. 3. … Read more

The programming principle of Flash is that it can only write 1 as 0, but cannot write 0 as 1. Therefore, before programming Flash, the corresponding block must be erased, and the erasure process is to write all bits as 1, turning all bytes in the block into 0xFF. Thus, programming can be said to … Read more
Following the previous article, we learned about the erase, write, and read functions of FLASH, but there is still a lack of understanding regarding the relationship with JTAG. This article supplements the JTAG part. First, let’s take a look at the hierarchical structure of JTAG programming FLASH, as shown in the figure below: The physical … Read more
Previously, I shared a document-based tutorial on creating an SPI Flash programming algorithm. However, feedback from users indicated that it was not very convenient to port to other microcontrollers. This post is created to facilitate the migration to various platforms. Application scenarios for the SPI Flash programming algorithm: 1. In an IDE environment, such as … Read more
