Burn OPT bits

Hi ,

About the OTP bits setting, I have follow questions:

(1)If I can burn OTP bits from time to time in i.MX28?

(2)If freescale provide bit_settings.txt for i.MX28 secure boot, where I can get it?

Thanks very much.

Hi gary

for secure boot please refer to AN4555 Secure Boot with i.MX28 HAB v4

utility for burning fuse:

IMX_OTP_TOOLS : A set of tools for managing OTP bits on the i.MX23 and i.MX28.

Best regards
