The crystal isn't same. #56

Can the crystal is in HC49-SD package, 8MHz and 20pF load capacitance replace 8MHz and 18pF load capacitance when Cl1 and Cl2 aren't changed.

According to calculations https://github.com/bbogush/nand_programmer/wiki/Components they should be 33pF but 30pF is also good.

But the Win10 computer cannot recognize the chip and can only recognize the port.STM software shows that the connection cannot be made.

Ok.It's good.But I don't know how to add the new nand.I have the TH58NVG5D2ETA20 Datasheet.But I don't find the some parameters by the datasheet,because it's different.For example,total size,page size,spare size,block size, bb mark off,Col.cycles,Row cycles.

It's ok.
