LPC2362 Not entering ISP mode

Hi All,

I have a strange problem with my board LPC2362. The fresh controller is getting programmed for the very first time. And the second time onwards the controller is not entering into ISP mode.

I am using Flash magic for programming. RTS and CTS are included in the ISP connections and using via PC serial port.

I have probed the Reset pin and EINT(P2.10). Both are going LOW initially and then HIGH when trying to connect from flash magic, though not connecting on second attempt. The error I get is Failed to Autobaud.

First time after changing the controller, it works fine. So the ISP circuit is fine I guess.

Any valuable suggessions would be highly appriciated.

Thanks

  • Are you erasing all the flash blocks while programming using ISP? (Check the configurations of Flash Magic to determine this.)
    Its likely that you are erasing the Bootloader code also.
    check box "Erase blocks used by Hex File" must be checked (ie enabled)
