How to program the winbond NAND W29N01GVSIAA

[800908]

Hi
I have winbond NAND chip that I want to read and write on it.
there is UART test points on the device that I can connect it to black CH341a programmer but I don't know how.
the part number is W29N01GVSIAA.
thanks.

Programming it in circuit - depends on the device. Having UART may not be enough.

Outside of the circuit - using any programmer that supports NAND devices.

thanks Alex.
the device also has E-JTAG test points.
is this help reading and writing?
I searched the internet for NAND programmer but all I found was for Apple iPhone.
do you know any cheap one that can do the job?

I'm not sure what "E-JTAG" is. If you have an actual JTAG port, then it still depends on the device that this port goes to. Generally you can use boundary scan to access the NAND flash pins and bit bang the read/write sequence. It will be slow (very slow), but this is the most universal method.  There are probably some standard tools for that, but I do't know any.

No idea, I've never used them. I know they exist, since USB flash drive recovery people use them. Not sure of price ranges.

I suggest you search the hddguru.com forum. I think there was a discussion in recent months on this subject.
