Hi @silver2row ,
My BBB has the part. num. AM3358BZCZ100 on it… as far as I understand from your question, I believe I have the ZCZ model.
Thanks Seth, I’ll search more about the PRU… I found this document, I’ll read it out and seek if something catch my attention.
Hello,
I know very little on PRU stuff in general. I think you have the ZCZ too. This is good news (I think).
The above datasheet documentation I found is showing Mode 3 for setting up the pins.
For instance for Ball #D13, McASP0_AXR1 is the pin that corresponds to the mcasp1_axr0 muxing (P9_41).
I think this should help a bit when typing up the overlay. So, P9_42/27/41 all need to be in Mode 3.
So, Frame Sync is McASP0_FSR which is mcasp1_fsx (P9_27)
And, Bit Clock is McASP0_ACLKR which is mcasp1_aclkx (P9_42)
And then, I2S Data is McASP0_AXR1 which is __________ (P9_41) + THIS MAY BE THE ISSUE
So, P9_27 is a McASP GPIO?
/* P9_27 (ZCZ ball C13) gpio3_19 */
P9_27_default_pin: pinmux_P9_27_default_pin { pinctrl-single,pins = <
P9_27( PIN_OUTPUT_PULLDOWN | INPUT_EN | MUX_MODE7) >; }; /* mcasp0_fsr.gpio3_19 */

P9_27_gpio_pu_pin: pinmux_P9_27_gpio_pu_pin { pinctrl-single,pins = <

P9_27_eqep_pin: pinmux_P9_27_eqep_pin { pinctrl-single,pins = <

P9_27_pruout_pin: pinmux_P9_27_pruout_pin { pinctrl-single,pins = <

P9_27_mcasp_pin: pinmux_P9_27_mcasp_pin { pinctrl-single,pins = <
P9_27( PIN_INPUT_PULLDOWN | MUX_MODE0) >; }; /* mcasp0_fsr.mcasp0_fsr */
and…P9_41 is P9_91 which is available as P9.41.1?
/* P9_41.1 */
/* P9_91 (ZCZ ball D13) gpio3_20 */
P9_91_default_pin: pinmux_P9_91_default_pin { pinctrl-single,pins = <

P9_91_gpio_pin: pinmux_P9_91_gpio_pin { pinctrl-single,pins = <
P9_91( PIN_OUTPUT | INPUT_EN | MUX_MODE7) >; }; /* mcasp0_axr1.gpio3_20 */
P9_91_gpio_pu_pin: pinmux_P9_91_gpio_pu_pin { pinctrl-single,pins = <
P9_91( PIN_OUTPUT_PULLUP | INPUT_EN | MUX_MODE7) >; }; /* mcasp0_axr1.gpio3_20 */
P9_91_gpio_pd_pin: pinmux_P9_91_gpio_pd_pin { pinctrl-single,pins = <
P9_91( PIN_OUTPUT_PULLDOWN | INPUT_EN | MUX_MODE7) >; }; /* mcasp0_axr1.gpio3_20 */
P9_91_eqep_pin: pinmux_P9_91_eqep_pin { pinctrl-single,pins = <
P9_91( PIN_OUTPUT_PULLUP | INPUT_EN | MUX_MODE1) >; }; /* mcasp0_axr1.eqep0_index */
P9_91_pruout_pin: pinmux_P9_91_pruout_pin { pinctrl-single,pins = <

P9_91_pruin_pin: pinmux_P9_91_pruin_pin { pinctrl-single,pins = <
P9_91( PIN_INPUT | MUX_MODE6) >; }; /* mcasp0_axr1.pru0_in6 */
and then P9.42, which I called the issue may be done but as P9_42.1 as listed below:
/* P9_42.1 */
/* P9_92 (ZCZ ball B12) gpio3_18 */
P9_92_default_pin: pinmux_P9_92_default_pin { pinctrl-single,pins = <
P9_92( PIN_OUTPUT_PULLDOWN | INPUT_EN | MUX_MODE7) >; }; /* mcasp0_aclkr.gpio3_18 */
P9_92_gpio_pin: pinmux_P9_92_gpio_pin { pinctrl-single,pins = <
P9_92( PIN_OUTPUT | INPUT_EN | MUX_MODE7) >; }; /* mcasp0_aclkr.gpio3_18 */
P9_92_gpio_pu_pin: pinmux_P9_92_gpio_pu_pin { pinctrl-single,pins = <
P9_92( PIN_OUTPUT_PULLUP | INPUT_EN | MUX_MODE7) >; }; /* mcasp0_aclkr.gpio3_18 */
P9_92_gpio_pd_pin: pinmux_P9_92_gpio_pd_pin { pinctrl-single,pins = <
P9_92( PIN_OUTPUT_PULLDOWN | INPUT_EN | MUX_MODE7) >; }; /* mcasp0_aclkr.gpio3_18 */
P9_92_eqep_pin: pinmux_P9_92_eqep_pin { pinctrl-single,pins = <
P9_92( PIN_OUTPUT_PULLUP | INPUT_EN | MUX_MODE1) >; }; /* mcasp0_aclkr.eqep0a_in */
P9_92_pruout_pin: pinmux_P9_92_pruout_pin { pinctrl-single,pins = <
P9_92( PIN_OUTPUT_PULLDOWN | INPUT_EN | MUX_MODE5) >; }; /* mcasp0_aclkr.pru0_out4 */
P9_92_pruin_pin: pinmux_P9_92_pruin_pin { pinctrl-single,pins = <
P9_92( PIN_INPUT | MUX_MODE6) >; }; /* mcasp0_aclkr.pru0_in4 */
I know this may be short or not to the point. I think this is done for a reason. The reason is out of my control.
Seth
P.S. I do not know the difference between P9_THE_PIN and P9_THE_PIN.1 and so I am lost. I will keep researching.
The ZCZ and ZCE package is a bit awkward… I say that b/c in the datasheet, one can use straight ZCZ or the ZCZ/ZCE package which is more complicated but can be noted down and done…
P9_27 has the incorrect ball allocated to it these days (I think) for i2s use:
# P9_27 for Kernel 4.19.x at am335x-bone-common-univ.dtsi
/* P9_27 (ZCZ ball C13) */
P9_27_pinmux {
compatible = "bone-pinmux-helper";
status = "okay";
pinctrl-names = "default", "gpio", "gpio_pu", "gpio_pd", "eqep", "pruout", "pruin";
pinctrl-0 = <&P9_27_default_pin>;
pinctrl-1 = <&P9_27_gpio_pin>;
pinctrl-2 = <&P9_27_gpio_pu_pin>;
pinctrl-3 = <&P9_27_gpio_pd_pin>;
pinctrl-4 = <&P9_27_eqep_pin>;
pinctrl-5 = <&P9_27_pruout_pin>;
pinctrl-6 = <&P9_27_pruin_pin>;
pinctrl-7 = <&P9_27_mcasp_pin>;
}
I looked up the McASP1 definitions at ZCZ and ZCE/ZCZ pins but have not come across the what is pinctrl-0-8.
But okay about your conclusion: I guess using HDMI and McASP0 may be the only way w/out getting some of the beagleboard.org people involved. I am a community person trying only and dually noted, by myself here. So, some things are a bit convoluted.
p. 208 in sprs717l is a start w/ McASP in general. I think I may be out for the night. Good luck until next time. Okay.
p. 208 provides me nothing. I think looking at the balls, BGA on the am335x, to see what exactly is available and if it is muxed will provide a better solution, e.g. whether to contact the beagleboard.org people to try to make your system function or keep dealing w/ guess work from me. No offense and I am sorry if I cornered you, in a sense, into thinking I could provide a 100% solution.
So, please forgive me. I cannot provide the exact solution but only clues is all I can offer. The beagleboard people are fully in charge of their own OS and what they will accept to be a part to their organization. I am sort of like a lamprey on a shark (just some user that enjoys computing).
