Hello!
The dap4 pins are …
dap4_fs_pj4
dap4_fs_pj5
dap4_fs_pj6
dap4_fs_pj7
The ‘pjX’ indicates that the corresponding GPIOs are J4-J7. So we care about the GPIOs in the row starting “J:”. Now the output above shows that the ‘CNF’ value for ‘J’ is 0xf0 and this means that J4-J7 are GPIO and not I2S.
Did you re-flash the DTB files after modifying them?
Regards,
Jon
