Hello,
i have the Zedboard which contains arm Cortex-A9 cortex with the amba bus..
i have searched a lot but I probaly miss the point.
i want to use data and to transfer data from the processing system to the programable logic section via the amba bus
is there any library for c that have function to implement the amba bus ?
for example
sendDatatobus(data,addr)
or something like that?
how do I do it?
thank you!
idan.

Assuming you have solved the hardware side of things and managed to wire up your peripherals in the programmable logic area, the AMBA bus itself is just address based. The programmable logic region is assigned a portion of the AMBA address map, and your peripheral should exist in that area, so you can write to the peripheral just by writing data out via pointers which point at the appropriate peripheral memory slave address.
