DRA821U-Q1: OSPI flash boot

Part Number: DRA821U-Q1

Tool/software:

Can you help to tell what should be set for these 3 bits in above table?

OSPI: MCU3 = ? MCU4=? MCU5=?

USB: MCU3 = ? MCU4=? MCU5=?

eMMC: MCU3 = ? MCU4=? MCU5=?

or we ignore these 3 bits when we can configure OSPI, USB and eMMC bootmode?

Thanks

Max

  • sorry it was typo

    it should be:

    OSPI boot: SYS4 = 0, SYS5 =1, SYS6 = 0 which I used CS0, correct?

    eMMC boot: SYS4 =0, SYS5=0, SYS6=0, correct?

    USB boot: SYS4=0, SYS5=0, SYS6=0, correct?

    in this table also mentioned "33MHz using manual tap selection", can you explain manual tap?

    Thanks
