Other Parts Discussed in Thread: AM3358
HI, acording to https://e2e.ti.com/support/legacy_forums/embedded/linux/f/354/t/602825?Linux-PCM1865-AM3358-McASP-no-data-while-recording I am trying to configure pcm1865 with am335x board.
I am using codecs from ti-sdk. I build device tree and board configure pcm 1865 while starting (clocks are visible with osciloscope) but when I am trying to record I got: arecord: pcm_read:2143: read error: Input/output error.
From dtsi I use only pin lcd_data14, lcd_data11, lcd_data13, lcd_data12.
My dtsi file:
&am33xx_pinmux {
mymcasp0_pins_default: mymcasp0_pins_default {
pinctrl-single,pins = <
0xc0 ( PIN_INPUT_PULLUP | MUX_MODE3 ) /* (U1) lcd_data8.mcasp0_aclkx */
0xc4 ( PIN_INPUT_PULLUP | MUX_MODE3 ) /* (U2) lcd_data9.mcasp0_fsx */
0xd0 ( PIN_INPUT_PULLUP | MUX_MODE3 ) /* (V2) lcd_data12.mcasp0_aclkr */
0xd4 ( PIN_INPUT_PULLUP | MUX_MODE3 ) /* (V3) lcd_data13.mcasp0_fsr */
0xc8 ( PIN_OUTPUT | MUX_MODE3 ) /* (U3) lcd_data10.mcasp0_axr0 */
0xd8 ( PIN_INPUT_PULLUP | MUX_MODE3 ) /* (V4) lcd_data14.mcasp0_axr1 */
