I have a question about i.MX6S CLKO.
I tried output 32kHz from CCM_CLKO1 with the following settings.
However, it does not output even though external 32kHz crystal oscillates certainly.
IOMUXC_SW_MUX_CTL_PAD_GPIO05 = 3; (Select CCM_CLKO1, SION=0)
IOMUXC_SW_PAD_CTL_PAD_GPIO05 = 0x0001B0B0;
CCM Clock Output Source Register (CCM_CCOSR)
8 CLK_OUT_SEL ： 0 CCM_CLKO1 output drives CCM_CLKO1 clock
7 CLKO1_EN ： 1 CCM_CLKO1 enabled.
6-4 CLKO1_DIV ： 000 divide by 1(default)
3-0 CLKO1_SEL ： 1110 ckil_sync_clk_root
Is any additional setting needed to output 32kHz from CCM_CLKO1?
If no additional setting is needed, could you let me know what is considered as a possibility of a root cause?
For your information, 24MHz is output from CCM_CLKO2 with similar setting as above.
