Functions

void os_MSDGetMaxLUN(uint8_t *value)

Perform an MSD GetMaxLUN request, either through the USB port or with an ARM coprocessor.

Parameters

value – [inout] On input the wValue to use in the request (should be zero for usb?), on output the max logical unit number.

void os_MSDReset(uint8_t value)

Perform an MSD mass storage reset request, either through the USB port or with an ARM coprocessor.

Parameters

value – [in] Affects the wValue of the request, 1 for 0x55AA, 2 for 0xAA55, otherwise 0x0000 (for usb).

int8_t os_MSDInquiry(uint8_t lun, uint8_t *inquiry)

Performs an MSD inquiry, either through the USB port or with an ARM coprocessor.

Parameters

  • lun – [in] Logical unit number.

  • inquiry – [out] Buffer where the response is stored.

Returns

Error code, 0 for success, 5 for failed command, -5 for failed transfer.

void os_MSDTestUnitReady(uint8_t lun, uint8_t *status)

Performs an MSD test unit ready command, either through the USB port or with an ARM coprocessor.

Parameters

  • lun – [in] Logical unit number.

  • status – [out] Returns the status of the command.

int8_t os_MSDReadCapacity(uint8_t lun, uint32_t data[2])

Performs an MSD read capacity command, either through the USB port or with an ARM coprocessor.

Parameters

  • lun – Logical unit number.

  • data – Returns the returned logical block address and block byte length.

Returns

Error code, 0 for success, 5 for failed command, -5 for failed transfer.

int8_t os_MSDRead(uint8_t lun, uint8_t blockCount, uint32_t lba, uint24_t blockSize, void *buffer)

Performs an MSD read command, either through the USB port or with an ARM coprocessor.

Parameters

  • lun – [in] Logical unit number.

  • blockCount – [in] Number of blocks to read.

  • lba – [in] Logical block address to start reading from.

  • blockSize – [in] Block size, obtained from os_MSDReadCapacity().

  • buffer – [out] Buffer to read data into, should be blockCount * blockSize bytes.

Returns

Error code, 0 for success, 5 for failed command, -5 for failed transfer.

int8_t os_MSDWrite(uint8_t lun, uint8_t blockCount, uint32_t lba, uint24_t blockSize, void *buffer)

Performs an MSD write command, either through the USB port or with an ARM coprocessor.

Parameters

  • lun – [in] Logical unit number.

  • blockCount – [in] Number of blocks to write.

  • lba – [in] Logical block address to start writing to.

  • blockSize – [in] Block size, obtained from os_MSDReadCapacity().

  • buffer – [in] Buffer of data to write, should be blockCount * blockSize bytes.

Returns

Error code, 0 for success, 5 for failed command, -5 for failed transfer.
