2.3.4 Status Command

Use the CMD_GET_STATUS command to check the status of the bootloader. Check the status after erasing or writing the flash memory to be sure that the erase and write were successful before proceeding. Table 2-13 shows the possible status codes for the CMD_GET_STATUS command.

Table 2-13 Possible Status Return Values From Bootloader
Status Definition Value Description
COMMAND_RET_SUCCESS 0x40 Status for successful command
COMMAND_RET_UNKNOWN_CMD 0x41 Status for unknown command
COMMAND_RET_INVALID_CMD 0x42 Status for invalid command (incorrect packet size)
COMMAND_RET_INVALID_ADR 0x43 Status for invalid input address
COMMAND_RET_FLASH_FAIL 0x44 Status for failed attempt to program or erase the flash
