Tool/software:

Dear Champ,

My customer is doing DRA821 SR 2.0 security on their own board with DRA821 SR 2.0 sample.

Customer has both GP and HS-FS sample on their board and can boot on both boards now.

However, the OTP writer in mysecuresoftware indicates J721S2 OTP Keywriter SR1.0 the tiboot3.bin build from this installer cannot boot on customer board successfully.

So I am writing to confirm whether there is OTP keywriter for SR2.0 or using SR1.0 is the right approach?

BR, Rich

Hi Rich,

Can you confirm which device you are actually using. From the above statement it seems that you are using J721S2 keywriter on DRA821 , which are totally different devices.
