    [moved] Cheap flash programmer

    I need to read/write NAND flash chips( only from time to time as a hobbyist) . I was thinking about a development board, where I would replace NAND flash chip with a SMD TSOP48 socket( yes the NAND chips I work with are for this socket only).
    I will insert a NAND into this socket and will read or write into it via JTAG
    If the original NAND have the same size as the NAND chip I am programming, it should work. But what If I need to program( read or write) a NAND with the different size than the original NAND ? Is it possible to set the size of NAND chip on a development board? Or how expensive programmers solve programming of different sizes of flash chips?
    Thank you for explanation and your oppinion

    Re: [moved] Cheap flash programmer

    I'd take a look at the "Willem" programmer, which seems
    to be continuing to evolve but has served me well for
    much older EPROMs. I know it handles many others I had
    no interest in.

    I used mine with a PC, no idea whether it's practical to
    interface to a JTAG port.

    If you have a weirdball package, there are outfits that
    specialize in adaptors to more normal footprints - forget
    their names, but find them at the back of many electronic
    design and products magazines, and "IC package adaptor"
    ought to turn you up something.

    Thank you for your reply.
    However "Willem" programmer is rather old and I did not find NAND suport in the list of supported models

    Best to find a Test Engineer friend in Production who can do for you a case of brew.

    A best design is easily achieved with good test specs™
    A better question deserves a better answer. ™
    ... so include all your acceptance criteria ( values, % tolerance) and assumptions in your question or any design.
