TAS3308 boot via slave I2C download

Kevin Lee59777

Hello.

I am trying to replace the EEPROM with MCU slave download for cost saving.

I have got the .cfg from PPS 188b3, 188b5 , edit it carefully and then download via I2C.

After downloading F/W , the status register shows 0x162 (D40 - D32),

D40 D39 D38 D37 D36 D35 D34 D33 D32

1 0 1 1 0 0 0 2 0

My cfg file has no micro external part.

Please let me know the details of the slave boot process and its check point.

Thanks for your support.

In the TAS3x0x_Microcode source code, it has compiler option MASTERLOAD / SLAVEDOWNLOAD.

When I use the option SLAVEDOWNLOAD , re-compile the code and republish the component,

I've got the same result as above.

Please let me know how can I use the SLAVE Download option for mass production.

Hi Kevin

You don't have to carefully modified .cfg files, the i2c slave mode will be create a .h file

the you can use it in c kde!
