4.6.9.4. Injecting SDM ECC Errors: Mailbox Command

To inject ECC errors, send the mailbox command with the following syntax: 
INSERT_ECC_ERROR [0x42]

This command inserts ECC errors into the selected RAM of CNT/SDM and triggers the ECC errors by performing a readback. You can only insert single bit ECC errors.

To inject ECC error via the Configuration Debugger tool, send 0x42 as the Command Code and 0xA0001 in the Parameter List field. 0xA0001 refers to single bit error at sector 10 (0xA) and RAM_ID is 0.
