Hello,
I'm working on a board equipped with a i.MX6 Solo/Duallite processor and was reguested to export a clock on a GPIO pin so it can be used by another board. I have looked into
the i.MX6 Solo/Duallite reference manual and found this at GPIO clocks sub-chapter:
ipg_clk_s Peripheral access clock
Can i use this clock source for external usage and if so how should proceed further? If this is not a good choice what clock should I use to "export" it on a GPIO pin ?
Thanks in advance,
Mihaita Ivascu
Hello guys,
Thank you for your answers. I use barebox bootloader and a imx6q BSP. I suppose the DCD entry is equivalent to devicetree(.dtsi) entry for GPIO3 IOMUX.
Also, i don't know where should I set in the kernel tree:
IOMUXC_SW_MUX_CTL_PAD_GPIO03
IOMUXC_SW_PAD_CTL_PAD_GPIO03
Thank you again,
Mihaita
Hi Mihaita
clocks can be outputted on pins CLKO1,2 please check
sect.18.6.21 CCM Clock Output Source Register (CCM_CCOSR)
Best regards
igor
