I am using EPM 900 programmer with DP9401 development board. During programming mode i am geeting the error message as "This is not p89LPC9401 device". Wht can be reason for this? I made all the setting correctly for the EPM900 and target.
The P89LPC9401 device just programs fine when it is correctly connected to EPM900.
You need to connect the ICP of the LPC9401 device to the related EPM900 pins. There are only 5 pins needed for ICP programming.
