as another alternative one can consider LVDSCLK1 (CCM_CLK1_N, CCM_CLK1_P balls)

described in sect.18.7.18 Miscellaneous Register 1 (CCM_ANALOG_MISC1n) i.MX6ULL Reference Manual 

https://www.nxp.com/webapp/Download?colCode=IMX6ULLRM 

But I didn't see any clock divider option on a sec.18.7.18 for 8MHz clock out from 24MHz.

Hi prabhu

one can try to output AUDIO_PLL (reprogram it to necessary frequency

using CCM_ANALOG_PLL_AUDIOn register) and dividers in AUDIO_DIV_LSB(MSB)

CCM_ANALOG_MISC2n.

Other alternatives may be try to use PWM, EPIT or GPT modules for such purpose.

GitHub - sasamy/imx-snd-pwm: A simple sound card based on PWM for i.mx6x processors 

 

Best regards
igor
