I tried to receive I2S audio data by gpio pins.
What i have to using gpio pin is "GPIO0_CAM0_PWR (G8) and connected by Max9296 for sound.
( HW teams did that…)
1st question is … how to connect to codec?
using DMIC? or how to set to data ouput pin on DT?
2nd question is how to setting gpio pins for i2s.
so i find to TX2 pinmux teamplate for enable that…
GPIO0_CAM0_PWR# G8 QSPI_SCK AW39 AV37 unused_QSPI_SCK GPIO3_PR.00 B B QSPI RSVD1 RSVD2 RSVD3 RSVD1 qspi_sck_pr0 vddio_spi LV_CZ BDSDMEMLV_BFCR90_VXVDP1P1P1 18k pd GPIO_PR0 NORMAL NORMAL DISABLE 0 1 1 1 1 1 1 VALID GPIO3_PR.00 Output Drive 0 Disable GPIO3/CAM1_RST#
… how to change that
direction is ouput and … pad category? pull strength?
