Hi,

At the power up, which core will RBL run on ?

It's R5F0-0 , not DMSC, correct ?

Does R5F0-0 execute both RBL and SBL ?

Regards,

Hello Hideaki-san,

The execution of code for something like an RBL is done through RAM so that SBL and application images can be loaded onto R5F core. The SBL would handle the configuration of the R5F after the RBL has executed.

Hi Ralph,

Thank you for your answer.

Just confirmation,

The answer is "YES", R5F0-0 core. Correct ?

Thanks and regards,
Hideaki

Yes Hideaki Matsumoto SBL will execute on R5f 0-0 but RBL or ROM Bootloader is stored in read-only memory and is almost considered as part of the SoC. Depending on which boot mode is selected, the RBL will load the secondary bootloader or SBL from a boot media (OSPI flash, SD card or via UART).
