Bert,

I also had a good look round and couldn't find EasyIAP anywhere. I emailed Microchip on the following address: contact_8051@microchip.com. I got a response within a day, with the .exe attached (renamed as a .txt to get through the filters).

If you look hard enough you can find a user manual for EasyIAP on the web.

If you still have a problem, give me another shout and I'll try to post what I've got here.

Soemthing else has occurred to me while looking round the NXP website. There is an upgrade from version 4 of the NXP bootloader to version 5. This is in the form of a hex file that is loaded into block 0 and, when run, it updates block 1 with version 5 of the bootloader.

When you get EasyIAP you could use it to download and run this upgrade file which should then give you an NXP bootloader in the SST MCU. I believe that you can then update the bootloader through FlashMagic to version 7, which I think is the latest.

There may be copyright issues however, although if NXP are abandoning the P89, perhaps they won't care. I haven't tried it yet but can't see why it wouldn't work.

Why would you want to do this? In our case we have a field upgrade path, and we have custom software to achieve this. A different bootloader means that we would have to rewrite the software or the manuals.

Let me know how you get on.

Regards,

Phil
