TDA4VM: MCU domain use the same software, different boot mode used time delay ~4 second.

Part Number: TDA4VM

Hi Experts:

We are working with customer try CAN early response demo at PDK folder.

At GP EVM board we find that different boot mode, from 12V power on to first UART print out log the boot time is different.

SYS_BOOTMODE[7:0]=0b11001010    MCU_BOOTMODE[9:0]=0b1100001000      the boot up time need ~ 5S.

SYS_BOOTMODE[7:0]=0b11001011    MCU_BOOTMODE[9:0]=0b0000000000      the boot up time is ~1.5S

Please check whether those time different is reasonable? 

Whether can you share the ROM code which part affect boot time delay so long time? 

Best Regards!
