I purchased 4 new NXP P89v51rd2 ics from a reputed shop and none of them are programming via ISP. the flash magic screen waits indefinitely in "reset into ISP mode now".even the device id is not visible. serial communication loopback occurs perfectly from pc via max ic via the short on txt rxd pin of muc back to pc. atmel ics burnt via parallel programmer run perfectly in the development board so the crystal works fine......
the thing is that philips muc can be burnt via the parallel programmer but could not be run in the development board....i guess the bootloader is at fault........can anyone tell me how to program the bootloader hex file into the ic via a parallel programmer please?
