UART1_TXD can be GIO25 or GIO16 instead in dm365 we have one of them MUX_CFG(DM365, UART1_TXD, 3, 15, 3, 2, false) That means GIO16. So I can add : MUX_CFG(DM365, UART1_TXD_GIO16, 3, 29, 3, 3, false) The same can be said for other peripherals, because the same periperal can be available using different pins. >> So I'll need to add more MUX_CFG lines.. >> UART1_TX_GIOx >> UART1_TX_GIOy >> and then select the one I'm really using on my board. > > Still don't understand what you mean. > >> I'm afraid that setting gpios in my board file is not enough, because >> I see that other modules change my settings and I'm getting crazy to >> find where they set. >> I'll search tomorrow the MUX_CFG defines around in my kernel. > > They should all be in dm365.c... I check better in the latest kernel... Regards, Raffaele
