Hello Team,

If we can use infineon’s NOR flash(1Gb) S28HS01GT  for TDA4? Thanks.

    Hello TI Exporter,

    we find the NOR Flash S28HS521T is one of the supported devices by the SDK R07.03.00. 

    But we also find that for SBL bootup, there is a macro switch that defines the S28HS521T is just supported by the J7200 device.

    could you please confirm if the S28HS521T is supported by J7210 (TDA4VM)?

    Hello Juanli,

    The Infineon S28HS01GT part is a JEDEC 251/216 compliant part. This means the TDA4 ROM Loader uses a specific boot mode called xSPI. The xSPI boot mode on J721e is only supported starting w/ PG 1.1 devices. Hence, if you are using a 1.0 device you cannot use the Infineon S28 external flash.

    Thanks,

    Steve

    Hello Steven,

    Could you please confirm if the SDK SW supports S28HS01GT?

    We find the NOR Flash S28HS521T (same family with S28HS01GT) is one of the supported devices by the SDK R07.03.00. 

    But we also find that in the SBL bootup code, there is a macro switch that defines the S28HS521T is just supported by the J7200 device.

    Could you please confirm if the S28HS521T/S28HS01GT is supported by J7210 (TDA4VM)?

    Regards.

    Hi Jingchun,

    For the SBL located in the SDK RTOS v7.03 there is no "out of the box" support for the Infineon NOR Flash chip S28HS512T and TDA4VM (J721E). You would have to perform some development. The J7200 macro refers to a different SoC that exists under the Jacinto7 product family.

    Thanks,

    Steve

    Hi Jingchun,

    If you are using TDA4VM 1.0 silicon, you will be able to boot using SPI boot mode from the flash.

    If you are using TDA4VM 1.1 silicon, you will also be able to boot using XSPI boot mode from the flash.  This was a feature enhancement in boot rom.

    As Steve said, you may need to modify to perform some development to enable the part in the SDK in 1.0/1.1 silicon. There is no device limitation in supporting this flash part.

    regards,

    Venkat
