TAS2572: PPC3 Tool can't initial EVB

Hi Chih-sheng,

Can you please read the memory on address 0xa0?
If this memory is empty, please remove the jumper on J74, power on the EVM, and connect to the I2C master in PPC3. Then press connect, paste the script (included below) and then press execute. Then replace the jumper on J74 and try to connect to the PPC3 app again. 

w a0 00 00 54 41 53 32 35 37 32 2d 45 56 4d 00 52 45 56 2d 41 00 53 2f 4e 2d 30 30 30 30

Dear Ivan

How to execute command  to read/write memory in PPC3 Tool?

Hi Chih-sheng,

Can you please confirm if you have I2C master installed in PPC3? This is a separate plugin from 257x EVM app.

Hi Ivan

I already install I2C Master App successfully

The read format is "r a0" ?

I try to wirte "w a0 00 00 54 41 53 32 35 37 32 2d 45 56 4d 00 52 45 56 2d 41 00 53 2f 4e 2d 30 30 30 30"

The error message as below:

Hi Chih-sheng,

The read format is r xx yy zz:

• xx is the I2C address in hex value, always use the write address (LSB = 0)
• yy is the register address in hex value
• zz is the amount of consecutive register to read starting at yy

Can you share pictures of your EVM? I want to double check your jumper settings.
Please also provide details on how you're powering up the EVM.

At this point, I think there's some issue with the power or jumper settings that prevents the proper I2C communication.
