I've been reading a lot on this. I think I need a "memory copy" firmware so it can copy byte by byte all my "real firmware" to external ram. Are there any tutorials or info on this? Cypres Forums are dead, no info at all from them. LoadRAM() in cyusb.dll won't do the job. I wonder how does the EZ-MGR Control Panel load the firmware to external ram? Please help on this, since it is not documented at all. Regards, Gabriel Camiro
