【求助】STM32H750外置下载算法

请问有哪位大佬有H750XB基于openocd的w25q256下载算法?我现在用clion+openocd环境,下载算法怎么写都报错,用反客群友的w25q64模板修改,总是出错

试了w25q64,修改了引脚,烧录一次成功后,后面就烧录不了了,用测试qspi程序能读写flash,就是烧录不了,不知道为什么。下面是openocd的烧录信息:

@表慌张
现在我用的w25q64,使用您这个.cfg,我改成我板子的引脚,也报错,qspi flash可以确定是没有硬件问题的

要对照你的程序改cfg里的时钟,qspi等相关的配置

Re: 【求助】STM32H750外置下载算法

第一次成功,后面不成功,我好像在哪看到过,说是flash的烧写寄存器值被修改了,被改成不能烧录了,需要重新把寄存器的值重置后,才可以

有可能是状态寄存器里的QE位被使能了,就是第一次烧录之后,那个下载算法,顺手把QE位使能了,而且是掉电不丢失的那个位。导致下一次上电,flash默认就是按照QSPI模式工作。但是下载算法本身可能还是遵循SPI模式在下载。
