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

我的是w25q256的flash，模板用64改，也不行

比较一下w25q64和w25q256的区别
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

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
是哪个寄存器？

不知道这是什么原因
