DLN_BOOT_READ_FLASH Command and Response

The DLN_BOOT_READ_FLASH command is used to read the firmware, currently installed in the DLN-series adapter.

DLN_BOOT_READ_FLASH Command

Syntax

C/C++

typedef struct
 {
    DLN_MSG_HEADER header;
    uint32_t address;
    uint16_t size;
 } __PACKED_ATTR DLN_BOOT_READ_FLASH_CMD;

Parameters:

header

Defines the DLN message header DLN_MSG_HEADER. The header contains several predefined fields and is used to identify and route messages. You must fill the following fields before sending the command:

Field	Description
size	The size of the message. Must be equal to the size of the DLN_BOOT_READ_FLASH_CMD structure.
msgId	Identifies the message. For the DLN_BOOT_READ_FLASH command it must be set to 0x0905. You can use the DLN_MSG_ID_BOOT_WRITE_FLASH constant.
echoCounter	Can be used to link a command to a response. The response will have the same echoCounter value. This field can be any numerical value from 0 to 0xFFFF (65536).
handle	A handle to the DLN-series adapter.

address

An address to start reading from.

size

A size of the data to be read.

DLN_BOOT_READ_FLASH Response

Go to command

The adapter sends the DLN_BOOT_READ_FLASH response after the DLN_BOOT_READ_FLASH command execution. The response contains data about current device firmware.

Syntax

C/C++

 typedef struct
 {
    DLN_MSG_HEADER header;
    DLN_RESULT result;
    uint8_t buffer[256];
 } __PACKED_ATTR DLN_BOOT_READ_FLASH_RSP;

Parameters:

header

Defines the DLN message header DLN_MSG_HEADER. The response header contains the following fields:

Field	Description
size	The size of the message. It is equal to the size of the DLN_BOOT_READ_FLASH_RSP structure.
msgId	Contains the message id. For the DLN_BOOT_READ_FLASH response it is set to 0x0905. The DLN_MSG_ID_BOOT_WRITE_FLASH constant can be used to check the message ID.
echoCounter	Links a command to a response. The echoCounter value is copied from the respective command header.
handle	A handle to the DLN-series adapter. You can use the handle field to determine the adapter that have sent the response.

result

Contains the result of the command execution. For DLN_BOOT_READ_FLASH command DLN-series adapter can return the following result values:

Return Code	Description
DLN_RES_SUCCESS	Firmware data have been successfully read.

buffer

A 256-element array. Each of the elements is an 8-bit value.
