    Hi all,

    Compiler-IDE: Keil uVision 3.2

    Target: ST712FR2T6

    Dev board: Hitex - ST710F

    JTAG debugger: Keil ULINK

    I am having a great deal of difficulty programming a ST712FR2T6, we 'appear' to be able access using JTAG without any connection problems, however when trying to erase or program, an error says:

    Flash timeout, reset target and try again.

    If we attempt to run from ram, we get a verification error along the lines of offset X value x expected y.

    I have scoped the lines of the JTAG and all appear very much alike our dev board which works ok.

    any ideas?

    Regards,

    DaveE

    Hello DaveE,

    Try to reset[once or twice] your circuit from the RAM mode. Then erase your target[once or twice] in the RAM mode and then try to progarm it in the FLASH mode. I think this may help you out.

    Cheers,
