AC7811芯片调试FLASH报废了，样品哪里有的买？谢谢！

发表于 2021-5-7 16:55

要了一块demo板，调试BLDC电机，今天芯片无法下载，报错了。估计是FLASH坏了。打算买几个样片继续调试。
或者哪位高手能看看这是哪里出错了？我用的是JLINK V9. 谢谢！

八成不是读保护就是写保护，read back 看下0x08040000地址后面的数据，对比下参考手册eflash章节选项字节的描述，可以通过JLINK把选项字节重新写了

好的，谢谢JasonLee27！

发表于 2021-5-7 22:52

写保护了。无法弄了。

发表于 2021-5-7 23:51

直接找代理商要样品吧。

发表于 2021-5-8 10:33

读出来0x08040000后面48字节了，正在分析，看起来应该是读写都保护了，我看怎么写进去。改回来。怎么会这么容易出错呢？

请教一个问题，J-FLASH能对FLASH进行写保护，但是无法擦除，要怎么解决？AutoChip有FAE指导一下不？

能进ISP模式擦除，KEIL环境下也可以

修改为ISP下载后，又满血复活了，哈哈！

一般是很难的坏的
