Here’s some information about the flash SST39VF1601. Please help me to see whether the OpenOCD supports it or not. Thank you in advance!
In order to enter the CFI Query mode, the system must write three-byte sequence, same as product ID entry command with 98H (CFI Query command) to address 5555H in the last byte sequence.
Some commands (Do they belong to Intel command set?)
Sector Erase command: The Sector-Erase operation is initiated by executing a six-byte commandsequence with Sector-Erase command (30H) andsector address (SA) in the last bus cycle.
Block Erase command:The Block-Erase operation is initiated by executing a six-byte command sequence with Block-Erase command (50H) and blockaddress (BA) in the last bus cycle.
Chip Erase command: The Chip-Erase operation is initiated by executing a sixbyte command sequence with Chip-Erase command (10H)
at address 5555H in the last byte sequence.
