[Question]parallel fast flash programming

Thu Feb 23, 2006 11:31 am

hi !

I am trying to write at91sam7sxxx by using ATmega16-16pi.
I used a clock oscillator of 50 MHz.
I am looking into the flash read command operation table on the datasheet. In the contents of table I am trying to understand 2,3,4 items in detail.
Please check the 2nd item in the table.
I am wondering if 32 bit memory address first byte is the first byte which I am trying to write to or just a fixed value.
Please check the 3rd item in the table.
Could you let me know what "Flash Address" in this 3rd item means? Where is "Flash Address" in this item pointing to?
You can find "Flash Address" in the 4th item. Where is "Flash Address" in this item pointing to?
You can find "Flash Address" in the 5th item. Where is "Flash Address last byte" in this item pointing to?
Please check the 6th item. I am trying to increase "*memory address" and I am also trying to read 32 bit in one process. Should I excute the 4th item above to read 32 bits at one try?
Is it possible to send us how to code "Parallel Programming"? Please send me an example source code if it is possible.

Hi

You have an FFPI example in the ATMEL basic examples.

AT91SAM7S64-BasicFFPI-IAR4_30A-1_21

This example shows the code to test FFPI interface. from AT91SAM7S64 to other SAM7S.
