I have a Problem that's equal to that discussed in January this year (PPC Memory Management, 27. January 2006) in this group:
I also want to run my program out of the memory of the sdram of my Xilinx Virtex 2 Pro, unfortunately I get outputs from stdout/stdin only in the debug mode. But I can live with that, the more serious problem is, that the code seems not to work as it should, when running it from sdram.
I use the Ethernet-MAC on the Board together with LWIP and I get no packets send, when running the board in the normal way. When I switch into debug mode, I get the right behaviour and I receive packets send by the board.
I assume that this has something to do with the set up time of the PowerPC and the SDRAM. Does anybody know a solution to get the PowerPC oder SDRAM wait for initialization until the program is executed? I use the EDK 8.1i.
