管理员，请问您可以添加对三星K8Q2815 TSOP-56 NOR芯片的支持吗？该芯片不会读取或写入RT809H。这是一个非常受欢迎的NOR芯片，我不知道为什么它不工作。我试过使用类似的芯片来读取它，但数据总是在.BIN中乱码Spansion S29GL128P90TFIR2  - 忽略错误，但数据转储出现乱码Macronix MX29GL128ELT2I-90G  - 忽略错误，但数据转储出现乱码。你能修好吗？这是一个非常受欢迎的NOR芯片。

If I bypass this and click ignore, the chip reads but the data is messed up.

I've verified other chips and have no problems. It's just with the Samsung K8q2815 NOR package.

I read on the datasheet that A22 also is virtual chip enable for 2nd bank. The other chips you have supported don't have this. Maybe it's that?

Thank you very much. It appears that another friend has had the same problem with K8Q2815 but no solution.

K8Q2815 not working with RT809H

The interesting thing about this device, is its actually two 64Mbit dies combined (with CS#2 hardwired to A22). This of course is compounded by the fact that it does not use uniform sector blocks.

So there's no way those other algorithms will work. It's two 64Mbit dies essentially in one package. I hope we can add this to the list.

From the datasheet.

A22正在切换低/高选择第二家银行！这应该很容易在RT809H软件中修复！

The programmer will need to write with A22 held low to fill the 1st bank, then the programmer will need to hold A22 high to program the 2nd bank. Those algorithms will work just fine. I wish there was just way just just do do this with the RT809H software.
