S4/hex file download @ assigned address.....

[Guest]

Hi all!
I´ve recieved an Intel hex file from our distrubutor in the states and need to get it on a Atmel 29c020 chip. For some reason the guy´s over there has designed the file so i must recieve it at FE0000 to FFFFFF in the s4. Can this be done....anyone.

Cheers

Hi,

Atmel 29c020 and hex file to FE0000 to FFFFFF.
Atmel 29c020 is 256kbyte. So its address range is 0-3FFFF.
a. Fill S4 RAM with FFs
b. You should then send your HEX file to the S4 from PC.
It is then at 60000H to 7FFFFH. I presume you want to burn it at the end of the 29040 chip.
BURN 40000,7FFFF,00000
(or BURN 60000,7FFFF,00000 - only the relevant part)

Hope this helps,

Neil

I created a programm with Intel C for a 80C188 and I want part of the program on a Eprom (64k) and the other part on a Flash Eprom (128K). On my board Eprom has address between F0000 and FFFFF (power on is at FFFF0 according Intel); Flash Eprom has address between 60000 and 7FFFF. If code in Flash exceeds 64k (it exceeds 6FFFF) it overlaps with Eprom code because on S4, when I send hex file from PC, Eprom code is loaded between 70000 and 7FFFF (the upper part of S4 ram). Is it possible to avoid overlapping?
