Microcode Studio Plus Loader?

[koossa]

Hi Keith

1. When you programmed the bootloader into your PIC did you make sure that the MCLR pin was set as MCLR and not an IO pin ?

How do I do that?

2. Is your MCLR pulled up with a resistor or have you tied it directly to +5V ?

With a Resistor.

3. Is Microcode loader set to "Auto" baud rate or is it fixed at the wrong speed?

Yes, to Auto

4 Try the bootloader circuit with 100R instead of 10uF !

Thx, I will try that.

When the bootloader is displaying a message saying it is waiting for a reset, connect the MCLR pin to 0V momentarily and it should then reset the PIC and bootload the new program.

I have connect the MCLR PINT TO 0V, but it still don't work.
I'm using the Max1672 switching regulator, and it has a soft on pin, so I must press the ON button on my keypad for the power to go through to my PIC.
I have done this and then momentarily connect MCLR to GND, but still no luck?

Any idea what else I can try?
