i am having problems programming can you guys help me out? i was able to copy the eprom to a file, but when i try to copy it down to another chip it keeps failing, help
The chip I uploaded is 27c256 then in put a 27256 in the programmer, make sure it is blank (ok) then I press program at slowness speed starts to program then get error ( 0000c2:error!(file=78,chip=ff)this just one of the error messages, each time i try a different chip 27256 i have 4 of them each one gives me a different error
plug in the top programmer as usual go to the control panel >>system>>device manager and youll see jongo devices and windriver
it must be done in stages in xp the installed hardware drivers removed first
so youll notice a top win programmer pnp driver has poped up there {if not right click the user name at the top and select scan for hardware}
so double click the top win programmer icon and select the driver tab and uninstall when it asks !!! choose to delete the drivers associated files close this window and then do the same for the win driver
then !!! no restarts and unplug the hardware
now uninstall the topwin app clean up any left over dir's {shift delete} {like C:\Top} and then reboot and on desktop roboot install the latest version
and then when it comes to ?load driver click yes and let it close and finish
then again reboot and then !!! you can plug in the hardware and it will auto install when the menu for internet search comes up click no not this time
and then just set it to look for the driver automaticaly then start the software and check for coms and voltages etc i notice youll need to restart the software if you plug in an external supply to the programmer after starting the software or if coms gets lost in runtime dont know how this pans out if you do this then program stuff
however using the top2049 its very similar and i see support is fixed on 256k and 512 and no mention of 1mb types being fixed ill try 3.28 see whats new although i havent tried yet with a few exotic chips i have,,, it claims to program {need to find a use}
