I disabled all references of SAI3_MCLK in dts files, and now we editenv fdt_file m4 dts,. But it's still not working, In u-boot bootmcu pwm work fine, however it's desn't when boot android system. Under special instructions we use android not Linux. Please tell me where the problem is ?
Thanks you!
