How to burn OTP bits for iMX28

[liuxing]

Hi All,

   I want to confirm that the Freescale Manufacturing Tool means the mfg tool?

  If so,I can't find the difference between the os image and OtpInit.sb.Is the difference in ucl.xml file?

  Can you provide the ucl.xml example for burning OTP bits?

8.1.4. Burn the OTP bits
Use the Freescale Manufacturing Tool to burn OTP bits before updating the
device's firmware. The Manufacturing Tool looks for OtpInit.sb in its firmware
profile, so copy or move the OtpInit.sb file to the firmware folder under the
Manufacturing Tool's profile.

Yes, it mean mfgtool.The OTP area access feature is NOT implemented in GPMI NAND driver in any of our BSP releases.For this Micron part, the OTP data read & program is similar to typical page read & page program but using different command sequence. The customer can refer to  GPMI NAND driver and add code to validate the OTP area program, protect and read function.
