LPC 2148

[jilani]

I have LPC 2148 board and when I purchased this microcontroller, I got some sample codes with .hex fles  and flash magic loader tool. I am able to install the .hex file only once on to the microcontroller. But later on I am not able to install any program in it. Even previously loaded .hex file also failing with error as "can not auto baud in step 1".

I tried on 7.x version also

Please help me in this regard. If possible some pointers on solution.

Thank you,
Jilani

When the device is blank it enters ISP mode on every reset. When it has been programmed you then have to meet the requirements defined in the user manual from NXP.
