我个人感觉809H说明书里面关于25系列读写方法没有楼主这篇帖子写的详细，通俗易懂。强烈建议把这个帖子植入说明书，好让新手学的更快、更容易。为楼主点赞

新版和老版有什么区别？

I'm having trouble reading the W25Q128JV Chip, by using a test clamp, it usually works fine for me on other old Epson boards, but newer Epson boards like L3110, L3160, L4160, L6171, WF2860, XP4105.
It throws me an error, saying that the Chip ID does not match, even though I have already added the chip code manually, if I omit said error; Still the same problem, I proceed to read but the information in the buffer is empty.
I attach photos of my case.

THE QUESTION IS, DO I NEED THE 12V. FOR THE RT809H PROGRAMMER ????
