How to set OTP bits with MfgTool?

Hi,

I'd like to use mfg-tool to program an OtpInit.sb as part of production programming. The OtpInit.sb is produced by otp_burner.py.

This is a chunk of my ucl.xml:

<CMD type="boot" body="Recovery" file="OtpInit.sb" timeout="60">flashing OTP.</CMD>

<CMD type="boot" body="Recovery" file="updater_ivt.sb" timeout="60">Booting Update Firmware.</CMD>

....

But, this doesn't work. I think there must be some command that I need to execute after booting the OtpInit.sb image.

This is what I see on the debug console:

pitc_loader(8003)

loading pitc id 8003

pitc installed

initialize pitc 2280: id:8003

If I program this bootstream from BitInit.exe, it works fine, and I get:

pitc_loader(8003)

loading pitc id 8003

pitc installed

initialize pitc 2280: id:8003

pitc 8003: process_cdb(cdb:14)

k_pitc_cmd_write_otp_register_set

pitc 8003: process_cdb(cdb:11)

k_pitc_cmd_request_sense

-So, definitely something is missing.

in the mfgtool source, I see the section DWORD COpMxRomUpdate::InitOtpRegs() - but it is commented out for some reason - so is this functionality broken/unsupported?

I'm in a big hurry to get this working - production starts on Dec. 1st.

Thanks,

-Patrick
