I am trying to remove the manual pinmuxing code from the board file. In an effort to accomplish this, I am trying to get SPL_OF_CONTROL and SPL_PINCTRL to let me use the device tree(s) to initialize pin muxing.
I have the following defined: CONFIG_SPL_PINCTRL=y CONFIG_SPL_PINCTRL_FULL=y CONFIG_SPL_PINCTRL_GENERIC=y CONFIG_SPL_PINMUX=y along with CONFIG_PINCTRL_IMX=y CONFIG_PINCTRL_IMX6=y I put some debugging code into the imx6 pinctrl and I can see that U-Boot initializes it, but that same debug message doesn't appear in SPL. I looked through the spl build directory, and I can see the drivers have been built, and the map file shows they exist, but for some reason, it doesn't initalize. If I remove the UART pin-muxing from my board file, the text for SPL doesn't' appear at all, so it's clear pinctrl isn't setting up the proper muxing yet. I am trying to figure out how/where the pinctrl system gets initialized in SPL, and I was hoping someone might have some insight. thanks, adam _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
