Hi Everyone, im working on project in which i need to write measurement values from the PL's domain into the PS' memory, for which I have implemented logic to handle the communication with one of the AXI-HP ports. Sofar it is it working out in Simulation, but when it comes to implentations in petalinux, configured with respective xsa file, in runtime nothing seems to get through. I've read that it is neccessary to modify the device-tree of the dedicated project in order reserve some region in the memory, that can be used by the PL. But when i try to peek at it in the runtime of petalinux, it seems to be occupied by complete different data. My modification of the device-tree is the following: reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; reserved: buffer@0 { no-map; reg = <0x0 0x10000000 0x0 0x10000000>; }; }; reserved-driver@0 { compatible = "xlnx,reserved-memory"; memory-region = <&reserved>; }; If you ran into something similar, or might suspect what error i made? Best Regards, and looking forward to possible answers.
