Content-Type: text/plain; charset=ISO-8859-1; format=flowed Cc: linuxppc-embedded@ozlabs.org List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi Mohammad, I've just had a look at the messages you generously posted in the ml about your experience with linux on V4 FX12 FPGA. I'd like to ask your opinion about FX12 practical usability in this context (gigabit PLB TEMAC/linux). In this message http://article.gmane.org/gmane.linux.ports.ppc.embedded/16816 you say the device is completely full. If I understand correctly your system provides just the devices required to run the bandwidth test so it seems there is no room for user logic (I think you did not even add the memory controller required to access the NOR Flash containing bootloader, kernel image and root fs that is clearly mandatory for standalone product). Is that true? If it is, this limits a lot the flexibility of this architecture in this configuration. What do you think?
