Hello,

In SBL_Design.pdf, Offset between Meta Image1 and Meta Image4 is 0x180000.

How can I modify Uniflash flash address offset?

Hi,

I am not sure if you can modify that. May I understand reason to change the same.

Thanks

Hello,

My team changed flash memory 2M Byte to 4M Byte.

And I wish to update SBL_BACKUP_IMAGE_OFFSET from 0x00180000U to 0x00214000U.

Hi,

Are you able to load backup image @0x00214000U?

Thanks

Hi,

No I cant not load backup image @0x00214000U.

But when I define SBL_BACKUP_IMAGE_OFFSET as 0x0008000 and flash Backup Image as Meta Image 2, Backup Image is loaded well.

And I wonder if there is way to load Backup Image @0x00214000U.

I guess It might be related to Uniflash configuration.

Could you check If it is possible?

Hi,

It is not possible from UniFlash since it support only 2MB. You need to use qspiflash driver to update the flash beyond 2MB.

Refer: C:\ti\mmwave_sdk_03_03_00_03\packages\ti\drivers\qspiflash\test\xwr68xx

Thanks
