Question:
On the S25FL128Sxx/FL256Sxx, how is the location of the 4-kB Parameter Sectors configured?
Answer:
The S25FL128Sxx/FL256Sxx needs to be configured correctly. Please refer to the S25FL256SAGxx datasheet, page 59, Table 8.9 Configuration Register [CR-1]. CR-1 Bit2 (TBPARM) configures the 4-kB Parameter Sectors location. The Default value (from the factor) is '0'. Therefore, the 4-kB physical sectors are at the bottom (Low address) of a 64-kB uniform sector device option. No further action is required if the preference is to have the 4-kB parameter sectors at the bottom (Low address) location. However, if CR-1 Bit2 (TBPARM) is set to '1', the 4-kB physical sectors are at the top (High address) of a 64-kB uniform sector device option. The user is required to program Bit2 (TBPARM) to '1' if the preference is to have the 4-kB parameter sectors at the top (High address) location. Please set CR-1 Bit2 (TBPARM) to the desired value to configure the top or bottom location of the 4-kB Parameter Sectors.URL to S25FL256SAGxx datasheet (refer to pg. 59):
