Dear Ti e2e Community,
I didn't understand the terminologies tx-num-evt & rx-num-evt in device tree
Am using 16 bit 8 Khz sampling rate, I2S mode , could you please let me know what is the correct value that needs to be configured in tx-num-evt & rx-num-evt
&mcasp0 {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mcasp0_pins>;
pinctrl-1 = <&mcasp0_sleep_pins>;
status = "okay";
op-mode = <0>; /* MCASP_IIS_MODE */
tdm-slots = <2>;
serial-dir = < /* 0: INACTIVE, 1: TX, 2: RX */
2 1 0 0 /*AXR1 --> DATA 0/P FROM PROCESSOR, AXR0 --> DATA I/P PROCESSOR */
>;
tx-num-evt = <>;
rx-num-evt = <>;
};
If is set the tx-num-evt = <1>;
rx-num-evt = <1>;
From the reference manual
I see that means for one DMA transfers am I transfering 32 bit of data or 16 bit of data????? please correct me if my understanding is correct
Kindly do the needful as early as possible
Many Thanks in advance
