Hi all,
I have a raspberry pi cm4 where I put some custom data in the customer OTP and all is working well.
I recently bought another one which is the same model as the first ( no Wi-Fi/bt, 1gb mem, no emmc).
I programmed the OTP with vcmailbox and the same command and values as the other one.
In this second one, vcmailbox returns the correct data when reading the OTP, while “vcgencmd otp_dump” returns all zeros in rows 36-43.
In the first one both vcmailbox and vcgencmd otp_dump return the correct values.
I am a bit puzzled by this and will appreciate any help.
