Dear team,


I would like to ask about the use of OCRAM of i.MX6SL.

My customer is thinking about the use of OCRAM for their own boot loader.

They are trying to develop their own boot loader program which is loaded into OCRAM free area from boot device and it runs on OCRAM.

They think that they can use 24KB of ‘MMU Table’ area (0x00918000- 0x0091DFFF) in OCRAM after the first boot procedure by iROM code has completed.

That is, they can disable MMU at the start of their own bootloader execution. Then they can use the ‘MMU table’ area for their own program.

Is it true?
