STM32 的 Flash information block 部分,包含有特殊的选项字节,可以用于系统配置等信息, 其中还有两个有效字节(实际四个字节,两个是校验字节)的用户自定义数据字节。 在尝试写入用户自定义字节时,我遇到了写入错误,但是比对用户手册,已经完成了应有的步骤。 后来通过对比系统库的 example 中的 Flash 相关例子,看到正...
This article will focus on the latter as it will create a small code example aimed for the STM32G071 using the NUCLEO-G071RB board. It shows the steps needed to program the option bytes using the HAL API and some tips and tricks to prevent issues, but don’t worr...
It is also possible to program multiple USER option bytes simultaneously. This can be done by combining the defines for the option bytes API. Let us say, for example, you wanted to modify nRST_STOP, nRST_STDBY, and nRST_SHDW to be 1, 0, and 1 respectively: HAL_StatusTypeDef modifynRST...
从简单的例子开始：ST 官方的 HAL 库包里有很多例程，可以先从简单的 LED、按键、串口等例子入手，理...
Per bank: All option bytes must be written in one go. It is not possible to only write - for example - one word. Reserved bits must be written with "1" otherwise writing the option bytes will not work as expected and the verify of the written area will fail....
