AM2434: QSPI/SPI Boot

Daisuke Maeda

Part Number: AM2434

Our customer wants to use QSPI and SPI Boot for AM243x.

MCU+ SDK supports only OSPI Boot for AM243x.

Does the SBL need to be modified to use QSPI or SPI boot?

Best regards,

Daisuke

    Hi Daisuke,

    Yes, if you want to support QSPI boot, you will need sbl_qspi. In MCU+ SDK 08.02.00.31, the sbl_qspi is there, but it is empty. It should be easy to change from sbl_osp, the only difference is the ospi uses 8 data lines while qspi uses 4 data lines.

    Best regards,

    Hi Ming-san,

    Thank you for your reply.

    I suggested to our customer to modify the SBL with reference to the Flash driver source code for SPI boot modes not supported by the MCU+ SDK.
