FS8530: Is OTP Programming/Burning possible for variants other than A0 ?

[BL_]

Hello NXP experts,

we're having the FS8530A1 samples and want to perform a OTP programming using FlexGUI.

By emulation everything works well, however by OTP programming an error occurred with the message "WP flag is present"

Since this information is for us currently very urgent, we hope to hear from you soon.

Thanks very much.

Hi,

thanks. It is clear now why we couldn't perform a OTP programming via FlexGUI for A1 version.

Thanks,

BL

A1 version means had already done OTP and can't be done again!

Is there any way to disable write protection? UM11183 says "The device configuration can be changed three times". I didn't see any expression that the A1 version can not be programmed 2nd or 3rd times. It just expressed as pre-programmed. So, regrettably, we bought a lot of A1 version and now we have to send back this SBCs.
