Hi Brad,

I double checked the sector and sizes. Also I saw into the Terasic demonstrations folder, a folder called EPCS patch, which has the override file which this content:

[EPCS-010216]# EPCS64N(lead-free)

sector_size = 65536

sector_count = 128

[EPCS-012018]# EPCS128N(lead-free)

sector_size = 262144

sector_count = 64

I put this content, and then the option with FF signature. The kit (DE2-115) has an original EPCS memory from Altera. It is weird, took like 5 hours I guess. But the previous log is not for an "erase-all" instruction, is for a programming image. However something is not working well.
