Riotboard -> imx6solo, sound (sgtl5000), no spi flash, 2 external sd/mmc interface (sdhc2 and sdhc3) and one eMMC (sdhc4), pmic (pfuze100), i2c1, i2c2 and i2c4 externally available, ssi interface. We could certainly create a dtsi file to be shared between them, but I do not know if it is worth the effort. What do you think? Best regards, Sergio Prado
