Hello,
there have been various discussions about the raw binary file format, solutions for the basically simple problem of retrieving the usercode have been already posted. http://www.alteraforum.com/forum/showthread.php?t=16118
If I remember right, the rbf header format has been previously described in the source of a NIOS programmer tool, at least for older FPGA types, e.g. Cyclone II.
Obviously the coding has changed between different devices, although the principle scheme (bit serial in bytes respectively dwords) is the same.
Now I want to add usercode decoding to a remote system update package, to allow rejection of invalid application images. Does anybody have information about rbf header coding of recent FPGAs, e.g. Cyclone V?
Best regards,
Frank
