Trouble Erasing Micron Flash using the Generic Serial Flash Interface

I am having troubles when I try to erase a Micron Flash (MT25QL256) using the Generic Serial Flash Interface in a Cyclone 5 (5CGTFD7C5). This 256Mbit flash part has 512 segments and each segment has...

Flavor 1 only has

- MII signals (Ethernet Interface) to the Intel Triple Speed Ethernet MAC core.

- Some custom logic that process these ethernet packets and converts them into Avalon bus interfaces and some internal custom bus interfaces

- One Avalon interface connects to the "CSR" interface on the Intel Generic Serial Flash Interface

- One Avalon interface connects to the "MEM" interface on the Intel Generic Serial Flash Interface

- the custom bus interfaces talks to other internal command/status registers

- An Intel Generic Serial Flash Interface Core

- An Intel Remote Update Core

Here are the summary statistics for Flavor 1

Family : Cyclone V
Device : 5CGTFD7C5U19I7
Timing Models : Final
Logic utilization (in ALMs) : 4,667 / 56,480 ( 8 % )
Total registers : 7945
Total pins : 114 / 268 ( 43 % )
Total virtual pins : 0
Total block memory bits : 114,688 / 7,024,640 ( 2 % )
Total RAM Blocks : 20 / 686 ( 3 % )
Total DSP Blocks : 0 / 156 ( 0 % )
Total HSSI RX PCSs : 0 / 6 ( 0 % )
Total HSSI PMA RX Deserializers : 0 / 6 ( 0 % )
Total HSSI TX PCSs : 0 / 6 ( 0 % )
Total HSSI PMA TX Serializers : 0 / 6 ( 0 % )
Total PLLs : 1 / 13 ( 8 % )
Total DLLs : 0 / 4 ( 0 % )

Flavors 2,3,4,5 have

- the exact same things listed in flavor 1 plus the following

- Various processing functions

- Intel Cores (Reed Solomon Decoder, Viterbi Decoder, FFT)

- Third Party Video Encoder Core

- Custom Radio signal processing blocks (Filters, FEC Decoders, Protocol Decoders)
