download data via jtag to spi dataflash

Hans Ehlers

Hello,

I'm using the AT91RM9200 controller with a dataflash (connected at the spi interface). But how could I download some data via the jtag interface to the spi dataflash?

I could not found any algorithm for the spi interface in the memory mapping of this controller.

And if I use the rom-algorithm (under options-for-target -> target) then I get the error message "no algorithm found for...." (I understand this message, but I don't know which start addr and size I have to choose for this dataflash

best regards
Hans

    Hi,

    first of all the addr for the spi interface is 0xc0000000.

    You are not able to download code direct to the spi interface without starting the spi controller. That means you have to write a small piece of code (maybe it is possible to run this code in the internal RAM) and after that you could download the code...

    And if I use the rom-algorithm (under options-for-target -> target) then...

    That's really not your solution!

    best regards
