Part Number: TDA4VM

Hi team,

Here's an issue from the customer may need your help:

When using OSPI as boot, what's the meaning of the boot resistor in the figure below?

Speed should only be 33M, right?

CSEL refers to the c hip select 0/1, right?

What is Iclk referring to? Is the clock for the OSPI flash based on the clock provided by TDA4 or the flash itself external clock? If it is a CLK provided by TDA4, then choose value 1?

Could you help check this case? Thanks.

Best Regards,

Cherry

Cherry,

The ROM only supports ICLK=1 (internal loopback mode).

Yes CS refers to the chip select (CS0 or CS1).
