Hi 7rots51,

Try this:

I have worked with RB2 / RC2 from Atmel but it seems that most is identical on RD2 too.

First find all the Erratas on ALL Rx2 from Atmel you probably need them.
1. ISP Download
- You can always activate the bootloader by the HW Contition.
and download Intel Hex records cia comport (Flip)
- after download remove the HW contition and do a HW reset.
2.IAP Download
- there is a API available at Atmel which you can use as a starting point
- don't try to use the block mode with more than 16 bytes. It will not work
- on RB2 I couldn't manage the bytemode successfully

I used IAP to update my FW via usb . The great thing about the Atmel is,
that there is no need (at least on RB2/RC2) to erease the Flash prior programming.

hope this helps

You don't need any special hardware.
Just connect TxT and RxD via Max232 to the PC Com port
Put PSEN to LOW via Jumper and do a HW reset and start Flip.

Of course you also need a XTAL and EA=VCC.

Check the datasheets and appnotes about HW contition.
