MW_DFU_FwImageRead

PIC32CX-BZ2

uint16_t MW_DFU_FwImageRead(uint32_t offset, uint16_t length, uint8_t *p_content);

Reads a fragment of the firmware image from flash memory.

The first 16 bytes of the image fragment read from flash are invalid until the full firmware image is updated.


Parameter	Description
[in] offset	The offset in flash memory from where to start reading the image fragment.
[in] length	The length of the image fragment to read, in bytes.
[in] p_content	Pointer to the buffer where the image fragment will be stored.


Return value	Description
MBA_RES_SUCCESS	Fragment of firmware image read successfully.
MBA_RES_INVALID_PARA	Invalid parameters. The sum of offset and length exceeds the maximum firmware image size Maximum image size, or the length exceeds the maximum block length Maximum block length.

uint16_t MW_DFU_FwImageRead(uint32_t offset, uint16_t length, uint8_t *p_content);

Reads a fragment of the firmware image from flash memory.

The first 16 bytes of the image fragment read from flash are invalid until the full firmware image is activated.


Parameter	Description
[in] offset	The offset in flash memory from where to start reading the image fragment.

[in] p_content	Pointer to the buffer where the image fragment will be stored.


Return value	Description
MBA_RES_SUCCESS	Fragment of firmware image read successfully.
MBA_RES_INVALID_PARA	Invalid parameters. The sum of offset and length exceeds the maximum firmware image size Maximum image size, or the length exceeds the maximum block length Maximum block length.
MBA_RES_FAIL	Flash access failed.
