duino33 Posted June 8, 2016 Share Posted June 8, 2016 Dear all,I need your help. I've built a fresh pcDuino3 firmware:Armbian 5.14 Pcduino3 -default - Debian 8 Jessie - CLI - Kernel 3.4.112 And now I'm trying to enable UARTs (2, 5 and 6).I've edited script.bin and now I got 4 ttyS devices. Could you please tell me how to "atctivate" those UARTs and which pins shoul I use. I guess thatUART2 (ttyS1) uses D0 and D1 pinsUART5 (ttyS2) uses SPI0_CS and SPI0_CLK pinsUART6 (ttyS3) uses SPI0_MOSI and SPI0_MISO pins Am I right ? And how to enable ttySs?I tried following for the UART2 echo 1 > /sys/class/gpio/exportecho 25 > /sys/class/gpio/export I attached my fex. file and pcDuino3 schema Unfortunately it does not help me. Thank you in advance. pcDuino3_Schema.pdf script_pcDuinoV3_4UARTs.txt Link to comment Share on other sites More sharing options...
