Thanks Bio_TICFSL

We just want to know since its only 4KB of Memory required to store the certificates does i.MX8 has any memory internally which we can be used for this purpose instead of having an external EEPROM for storing those certificates

Thanks

AMR

Hi Abdul,

Internal RAM can be used if you have no plan to use other peripheral and security of i.MX8.

Thanks Bio_TICFSL

U mean to say SECO RAM/ROM or any other internal memory. As we said before certificates should be stored persistently on hard/soft reset. Could you guide us to the respective source in the android source code which we can explore - if there are relative post/docs would also be helpful to us
