Introduction

Cypress S70FS01GS Flash non-volatile memory device implements JEDEC standard supporting Serial Flash Discoverable Parameters (SFDP). However, the S70FS01GS device is a dual die stack of two FS512S dies with consecutive memory addresses and prior to the first use initial formatting is required.

To use the S70FS01GS Flash Device, sector map needs to be configured. Configuration is set in the Configuration Register 3 Non-volatile (CR3NV). To configure the device, at least one of the 20h_NV bits in CR3NV registers of each die needs to be set.

 

The following index value combinations are supported for each die:

 

If the device is configured to one of the first two options, only one CR3NV register has been modified. In this case the device can still be configured to uniform 256 KB sectors.

 

The BlueBox debugger can configure Sector Map by either:

•Running a Python script via winIDEA

•Running a Python script via winIDEA SDK

 

 

 

Requirements

•winIDEA 9.17.160 or newer

•BlueBox

•Active Probe or Debug Adapter

 

 

Python script example

Download and unzip the script example via the link: S70FS01GS_sector_map_config.7z

 

The script includes all 3 available configurations. By default, script configures the 4 KB sectors at bottom, while the other two options are commented out. To select any other configuration, comment out the default configuration and uncomment the required configuration.
