The DE2 's fpga configs from EPCS16 (not CFI), is 2MB. The sof is not written directly to EPCS, it will be converted to RBF (raw binary file). The compress configuration data of 2C35 size around 300K-400K, typically. So you will have around 1.6MB unused space in EPCS16. You should store zImage after the RBF on EPCS. That is, you should use EPCS for fpga config and zImage. Then the CFI 4MB will be available for jffs2.
