problems while programming in chip

[arivalagan13]

hi,
i'm using CY8CKIT-001 PSoC® Development Kit.. while programming through MiniProg3 Program/Debug Device to the chip, i face a problem of downloading.... i can't able to program the chip more than 4-6 times.... while starting the program part it's showing error... what will be the problem? i also tried with the discrete IC CY8C29466-24PXI.. In that also i'm facing the same problem.... is there any problem with the chip? how can i check whether the chip is working or not? if so how to troubleshoot the problem in chip?

First check power-supply and the programmer's options do match and check the reset option.
I presume you try to program the PSoC1 processor module. That will work with the miniprog3 and the ribbon-cable. Programming any other PSoC1 will need the ISSP interface.
Can you provide us with any error-message (screenshot)?

infact checked the power supply connections and other stuffs(i was successful in programming the same for months now)..as a sudden am facing problem..

There is a program to download which disconnects all USB devices and de-installs them. Kind of clean up. Name of the program is USBDeview to be found at www:nirsoft.net
