ST M25M02-DR programming identification page

Postby ArT » Fri Mar 01, 2019 10:24 am

ST M25M01-DR and M25M02-DR I2C EEPROMs will be supported by REVEPLROG-IS from v1.8.1. Both devices are unusual because both have additional 256 bytes in memory area for "Identification Page" which may be permanently locked in read-only mode (write protected).

With REVELPROG-IS Custom Scripts tool there is possibility to:
  • Read Identification Page (256 bytes)
  • Write Identification Page (256 bytes)
  • Lock Identification Page

I'm sharing scripts for all these operations:

Read Identification Page (256 bytes)

Code: Select all

// M24M02-DR Read Identification Page (256 bytes)

#SCRIPT HEADER;
SCRIPT:v1.8.1;
#HARDWARE SETTINGS;
HW:I2C,5.0V,SLOW;

// Read 256 byte of identification page
#OPERATION;
SW:0,0,1,255,0,0,0,0,500,500;
INSTR:B0,00,00;


Write Identification Page (256 random bytes)

Code: Select all

// M24M02-DR Write Identification Page (256 bytes)
// Write will work only if Identification Page is unlocked.

#SCRIPT HEADER;
SCRIPT:v1.8.1;
#HARDWARE SETTINGS;
HW:I2C,5.0V,SLOW;

// Write 256 random bytes to identification page
#OPERATION;
