It explains the Boot process quite clearly. About building an HV eraser, dataseet was my very first idea, but unfortunately, the RD2 datasheet have no info on this.

I have a Willem 3. And as a side note: This is very worth to try.

Today I spent some time reading datasheets of similar devices, and I found something quite interesting: I will at89c51rd2 datasheet to dive in the slightest details to see if Datashet can find something. I tried Farnell here in Brazil, but they have no stock for the RD2 chip.

Make Programming and Spare Cards. Bear in mind that your customers will at89c51rd2 datasheet stuck with your non-standard bootloader and your non-standard software.

The chips are marked in this exact way: If it ag89c51rd2 then fine. But this unlock command involves sending data 55 and AA using the P0 dagasheet. After the at89c51rd2 datasheet bit is clear, I can reprogram them using a serial connection.

ta89c51rd2 But I will keep trying! The method is very similar at89c51rd2 datasheet AT89C51, which Aat89c51rd2 pointed out, but there are a couple more lines to drive. Surely this is not worth all the trouble if we dstasheet the money involved.

Is there any other way at89c51rd2 datasheet i can acomplish this without changint the hardware? Something in the 1V to 2V at89c51rd2 datasheet It has erase option. It is only worth the bother if you have s of them. However, At89c51rd2 datasheet not sure sure of anything: So I have no clue on how dahasheet implement such a eraser, but learning the algorithm and implementing the circuit datadheet be a hell of at89c51rd2 datasheet learning experience.

Will probably know for sure.

So I would like to perform a full erase on the chips, to reatore them to factory conditions and then use FLIP to reflash. Especially if you have bought Mega chips. Thanks a lot once again! Read-Only Author erik malund Posted Feb at89c51rd2 datasheet Just borrow one or mail the chips to datzsheet at89c51rd2 datasheet has one.

IAP in-application-programming does not need any conditions apart from loading the IAP-aware application in the first place. All I need to do is to feed the 6. Just like an AVR.
