Hi Team,
My customer has a question regarding xSPI boot.
About OSPI/xSPI/QSPI/SPI Boot
According to TRM Section 4.4.1.1.1.1 OSPI Initialization Process, 4.4.1.3.1.1 QSPI Initialization Process, 4.4.1.4.1.1 SPI Initialization Process, In those Boot mode, if the image fails to be read correctly from offset 0x0 of the flash memory, the ROM will attempt
to obtain the image at offset 0x400000.
But about xSPI boot mode, we can't find such a description. Doesn't xSPI boot mode have redundant image load function?
Best regards,
Mari Tsunoda
Yes , xSPI boot mode also attempts 0x400000 offset for the redundant image
Hi Ajay,
In the errata, i2257 Boot: xSPI boot mode redundant image boot failure, it says that it will not be able to boot from 0x400000. It also says that this will be resolved in 2.0 but will remain in 1.0 revision. Is it correct that they cannot redundant boot in 1.0 then?
Best regards,
Mari
Hello Mari,
That's correct, 1.0 doesn't have support for redundant image boot , Errata was correct and issue fixed in 2.0 revision.
Thanks & Regards,
Ajay
