I wanted to ask that i m programming the mcu p89v51rd2 with the parallel programmer P4MIC .
Just for simple testing i made a led toggling program in keil software.......
i first erased the previous things in the mcu and again programmed the mcu.
Tested it and found that all pins were high, i read again the mcu and found that the program was present in the chip.
When i use the same programmer and program for 89c51 mcu it works but not for p89v51rd2.
So my question is that have i erased the bootloader in the chip and is bootloader required for parallel programming.If not this please tell me other ways to parallelly program p89v51rd2.
Thaks in advance.....
