TDA4VM: Boot time benchmarking for OSPI boot mode and XSPI boot mode

Part Number: TDA4VM

Hello Team,

I am interested to use the Cypress S28HS01GTGABHB01 flash device with TDA4V/4A architecture. Based on earlier analysis by TI, the OSPI boot mode is not supported with the cypress flash device.

So i like to have the boot time estimation or boot time benchmarking reports for OSPI boot mode and XSPI boot mode.

As RTOS SDK 7.3 does not support XSPI boot mode, i also need an earliest time estimate for the XSPI boot mode availability on RTOS SDK.

Thanks and Regards,

Namash

    xSPI boot mode supports loading image in 8d-8d-8d mode @25Mhz (xSPI + SFDP mode) which should be faster than 1S-1S-8S (OSPI) mode  or 1S-1S-1S (SPI) mode of J721e Silicon revision 1.0.

    Customers will most likely use xSPI + SFDP boot mode for best performance.

    In essence XSPI is as per the JEDEC xSPI standard JESD251 & JESD216D and is supported by all compliant flash parts whereas OSPI is a non JEDEC standard supporting 1s-1s-8s boot.

    xSPI boot support is already there in RTOS SDK with SBL bootloader. If you have a flash part which is complaint to JEDEC xSPI standard JESD251 & JESD216D then you should be able to boot in xSPI boot mode.
