Part Number: TDA4VM-Q1


Hi TI!

I am wondering what is these BOOTMODE Pins if I select OSPI Bootmode.

/resized-image/__size/320x240/__key/communityserver-discussions-components-files/791/pastedimage1701769616679v5.png

1. BOOTMODE Pins 6 (Speed)

 if I select Value1 which freq. is operating?

2. BOOTMODE Pins 5 (Iclk)

 what is the Iclock? could you explain about it?

3. BOOTMODE Pins 4 (Csel)

 if I select Value 0, should I config OSPI's cs to 0?

Thanks.

    4.3.4 OSPI Boot Device Configuration clearly states that 'speed' should only be set to 0 as 1 is reserved.

    'Iclk' is affected by errata

    "i2307 Boot: ROM does not properly select OSPI clocking modes based on BOOTMODE", and therefore should be set to 0.
