I’m trying to change the pinmux of the following GPIO MX6_PAD_DISP0_DAT20__GPIO5_IO14 to MUX_PAD_CTRL(WEAK_PULLDOWN) in colibri_imx6.c. After change the source and updating the bootloader with run setupdate / update_uboot nothing changes to the output on the Colibri Imx6.
I’m trying to configure SODIMM 142 as pull-down at boot-time. Can you provide us some more information how to achieve this or provide some code example?
What i want is pulling the SODIMM pin to near 0 volts at boot time.
We already configured the device tree accordingly and confirmed the mux will be set while booting the kernel. We really need to set the mux as early as possible in the bootloader.
With kind regards,
