Other Parts Discussed in Thread: ADC5120EVM-PDK,
My TLV320ADC5120EVB daughterboard is connected to AC-MB motherboard. AC-MB is connected to my PC over USB. But PurePath Console(PPC3) shows the board as OFFLINE and not showing the CONNECT button.
All settings on two boards are default.
On AC-MB mother board:
USB READY LED is on in blue color.
On ADC5120EVM-PDK EVM board:
Measured +3.3V on test points IOVDD and AVDD.
D1 LED (AVDD) is on in green.
D3 LED (IOVDD) is off. It is 3.3V and 1.8V on the two ends of D3 LED.
Measured 48KHz clocks on FSYNC
Measured 12.2MHz on BCLK
On PC:
Texas Instruments USB Audio Device Control Panel:
It shows Current Sample Rate 48000Hz when plug in USB to PC, and show blank when unplug USB cable.
Device Manager:
It has Texas Instruments USB Audio Device -> TI USB Audio UAC2.0
PPC3:
On the left bottom corner: TLV320ADC5120 - OFFLINE
What might be wrong?
