5.1.5 Status Codes

After a command is completed, the kernel sends a status packet to the host with the same format as the host-to-device packet. This lets the host know if an error occurred, what type of error, and where the error occurred. The command field is the command last completed. The data field consists of a 16-bit status code followed by a 32-bit address where the error occurs. If there is no error the address is 0x12345678 unless the address is responding to a DFU command in which case the address is the entry point address of the hex boot format file of the application just programmed into flash. This address can then be used for the RUN command, which tells the CPU which address to branch to and begin executing code.

Table 5-8 displays the status codes.

Table 5-8 Status Codes
Status Code Value Description
NO_COMMAND_ERROR 0x1000 Return on Success
BLANK_ERROR 0x2000 Return on Erase Error
VERIFY_ERROR 0x3000 Return on Verify Error
PROGRAM_ERROR 0x4000 Return on Programming Error
COMMAND_ERROR 0x5000 Return on Invalid Command Error
UNLOCK_ERROR 0x6000 Return on Unsuccessful Unlock

For Program, Erase and Verify commands, if a Flash API error is detected, the error is displayed on the console. If an FMSTAT error is detected, the FMSTAT register contents is displayed.

Status Code Value
INCORRECT_DATA_BUFFER_LENGTH 0x7000
INCORRECT_ECC_BUFFER_LENGTH 0x8000
DATA_ECC_BUFFER_LENGTH_MISMATCH 0x9000
FLASH_REGS_NOT_WRITABLE 0xA000
FEATURE_NOT_AVAILABLE 0xB000
INVALID_ADDRESS 0xC000
INVALID_CPUID 0xD000
FAILURE 0xE000

For more details on the errors, see the device-specific Flash API guide.
