The command/data protocol is specific to any given PITC.
Only one PITC may be installed at any given time.
12.13.3 USB IDs and Serial Number
By default, the USB Device Descriptor Vendor ID, Product ID, and serial number are
reported as follows:
If any of the HW_OCOTP_ROM2 bits are blown, then the full contents of that OTP register
are used to report the Vendor ID and Product ID. If the
ENABLE_USB_BOOT_SERIAL_NUMBER OTP is blown, then a unique serial number
will be generated from the factory-programmed SGTL_OPS3 OTP registers.
12.13.4 USB Recovery Mode
USB boot mode is provided as a fail-safe mechanism for writing system firmware to the
boot media. The boot mode is not usually entered by the normal methods of setting the boot
pins or OTP, the other methods of entering USB boot mode are referred to generally as
recovery mode.
An end user can manually start the recovery mode by holding the recovery switch for several
seconds while plugging in USB. Holding the recovery switch is defined as reading the
i.MX28 PSWITCH input as a 0x3. There are several switch circuits that will produce this
input. The loader also automatically starts recovery mode if a non-recoverable error is
detected from any boot mode other than USB.
If the DISABLE_RECOVERY_MODE OTP bit is blown, then USB boot mode is disabled
completely. Attempts to enter USB boot mode through boot pins, OTP, or recovery methods
will result in a chip power-down.
