My customer plans to use OTP memory for Griffin secure boot.
Is this area allowed to be used at the discretion of the user?
Thanks and Regards,
Hi TanakaThere is no need to obtain permission from the Analog Devices to access the OTP Memory of the ADSP-SC5xx and ADSP-215xx Processors.The processors feature 7 Kb of one time programmable (OTP) memory which is memory map accessible. This memory can be programmed with custom keys and it supports secure boot and secure operation.Please note that Secure boot is an optional feature of the processor that is disabled by default. The feature is enabled using the OTP lock API; secure boot cannot be disabled after it has been enabled. When security is enabled, developers are not dependent on Analog Devices to provision the devices, sign code or provide security certificates. The required tools for signing and encrypting the boot images are provided with the processor development tools.Regards,Anand Selvaraj.
Thanks for your reply.
I understand very well.
