I am trying to run "talkthru analog in-out (asm)" on ADSP-21371 EZ-KIT Lite on 96 kHz, however, without success.
When I run the original program, that is configured to work on 48 kHz, it is working properly. I tried also to change "IMCLK Clocking Scaling" by changing the "ADC Control 3" register to use IMCLKx23 and IMCLKx2 (see ad1835.h) and this work OK, I obtained the Fs 24 kHz and 16 kHz.
However, when I set the DACCTRL1 register with DACFS96 and ADCCTRL1 register with ADCFS96 the output from DAC is zero. I can physically measure that the LRCLK and BCLK stay at 48kHz and 3.072MHz respectively, and the output is zero.
Am I doing something wrong?
