STM32F4 + HAL库 + W25Q256的验证

前言

今天验证打样板子上的W25Q256, 验证过了。做个笔记。

硬件电路

MCU = STM32F407IGT6
W25 = W25Q256JVEIQ 封装 = WSON-8 8x6mm
SPI方式读写，使用SPI2.

W25按照STM32接SPI设备的正常SPI方式连接, 为了布线方便，将SPI2管脚从默认管脚复用到PB12这边。

CubeMX配置

硬件电路上，SPI时钟线没接上拉电阻，将时钟管脚配置为上拉。
剩下用CubeMX默认选项,不用改。

W25Q256 HAL版驱动

csdn上有个同学写好了（https://blog.csdn.net/sudaroot/article/details/93158309），拿来验证一下，通过了。
那个驱动中，使用的是SPI5, 我这里是SPI2, 就这点区别。硬编码的SPI5句柄，用宏替代。

焊接

W25 = W25Q256JVEIQ 封装 = WSON-8 8x6mm
WSON-8的焊盘在芯片肚皮下面，两边只露出一点管脚，肚皮上还有一大片散热焊盘。用烙铁整的不靠谱，我在PCB上涂上锡膏，用热风枪吹的，因为买的锡膏注射器还在路上，用棉签挑的焊锡膏，涂的到处都是，第一次吹焊，芯片都不平。重新吹下来，将多余锡用烙铁弄掉，第二次吹焊才成功。
热风枪焊接确实挺方便，就看没钢网的情况下，用锡膏注射器效果咋样。

测试程序

按照扇区(4096字节)对齐进行扇区读写，好使。

焊完板子，实验w25读写之前，要先读下ID, 如果是0xEF，就说明w25q256设备焊的没问题。
在读ID之前，要先调用 BSP_W25Q256_Init(), 剩下的读写操作才正常。

调试这个板子，用JLINKV9各种问题，不知道是不是非原版JLINK的问题。不过正版JLINK也没必要用啊。

开始一直以为是自己板子焊接的挫或者原理图错了或者器件坏了或者器件值焊接错了。后来发现，是手头这个JLINKV9是坑货…, 害的我特意整了一个小板去打样。

只能使用STLINK(本次是STLINKV2)
