PCM1864-Q1: Question about PCM1864-Q1

Other Parts Discussed in Thread: PCM1864

Tool/software:

Hello：

The customer used TI's Audio ADCs PCM1864Q and needs to provide the relevant driver and register sequence for qnx initialization. The customer stated that the reference code on the official website is Linux (root/Documentation/devicetree/bindings/sound/pcm186x. txt). The customer attempted to port it to QNX, but the registers in the code are dynamically configured and not very suitable.

Can you provide a universal register configuration for PCM1864 Boot? Similar to the figure below, it includes register addresses and configuration values.

Hello Kevin:

Please help confirm if there are any issues with the device address: (corresponding to 7-digit address 4a --0x94 4b --0x96)

Page 0 failed to write but can be read normally. After attempting to reset the register, it still cannot be written, while other pages can be read and written normally;
