Hi Jon! I upgraded the kernel to the same version as you have. This is the output: root@beaglebone:~# /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin -q P2_18 P2_18 pinmux file not found! Cannot read pinmux file: /sys/devices/platform/ocp/ocp*P2_18_pinmux/state
Still not working. In uEnv.txt file, I have this added: uboot_overlay_addr6=/lib/firmware/PB-MCP2515-SPI1.dtbo This is the MCP2515 which could read the SWCAN bus if it was set to HIGH. jonn...@gmail.com a következőt írta (2020. október 19., hétfő, 3:32:13 UTC+2): > This is how to set say P2_18 as an output and high. > > debian@beaglebone:~$* > /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin -q > P2.18* > *P2_18 Mode: gpio Direction: in Value: 0* > debian@beaglebone:~$ > */opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin > P2.18 gpio* > debian@beaglebone:~$* > /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin P2.18 > out* > debian@beaglebone:~$ > */opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin > P2.18 hi* > debian@beaglebone:~$ > */opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin > -q P2.18* > *P2_18 Mode: gpio Direction: out Value: 1* > > > I don't think the /usr/bin/config-pin tool can do this. > > Cheers, > > Jon > > On Sun, Oct 18, 2020 at 6:17 PM jonnymo <jonn...@gmail.com> wrote: > >> With a PocketBeagle running Debian 10 (Buster) IoT image and kernel >> 4.19.94-ti-r51 I see this: >> >> *debian@beaglebone:~$ >> /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin -q >> P2_06* >> *P2_06 Mode: default Direction: in Value: 0* >> *debian@beaglebone:~$ >> /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin -i >> P2_06* >> *Pin name: P2_06* >> *Function if no cape loaded: gpio* >> *Function if cape loaded: default gpio gpio_pu gpio_pd gpio_input* >> *Function information: gpio1_25 default gpio1_25 gpio1_25 gpio1_25 >> gpio1_25* >> *Kernel GPIO id: 57* >> *PRU GPIO id: 89* >> *debian@beaglebone:~$ >> /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin -l >> P2_06* >> *default gpio gpio_pu gpio_pd gpio_input* >> >> *debian@beaglebone:~$ >> /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin -q >> P2_18* >> *P2_18 Mode: default Direction: in Value: 0* >> *debian@beaglebone:~$ >> /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin -i >> P2_18* >> *Pin name: P2_18* >> *Function if no cape loaded: gpio* >> *Function if cape loaded: default gpio gpio_pu gpio_pd gpio_input qep >> pru_ecap pruin* >> *Function information: gpio1_15 default gpio1_15 gpio1_15 gpio1_15 >> gpio1_15 eqep2_strobe pru_ecap pru0_in15* >> *Kernel GPIO id: 47* >> *PRU GPIO id: 79* >> *debian@beaglebone:~$ >> /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin -l >> P2_18* >> *default gpio gpio_pu gpio_pd gpio_input qep pru_ecap pruin* >> >> >> *debian@beaglebone:~$ config-pin -q P2_18 >> * >> *Current mode for P2_18 is: default* >> >> *debian@beaglebone:~$ config-pin -q P2_06* >> >> *Current mode for P2_06 is: default* >> >> >> Note, I did do a 'sudo apt-get update' and sudo apt-get upgrade' and then >> updated the scripts and such listed in the following Beaglebone Upgrade >> link including the 'update_kernel.sh' script. >> https://beagleboard.org/upgrade >> >> >> Cheers, >> >> Jon >> >> On Sun, Oct 18, 2020 at 5:50 PM Szabó Benedek Ákos <szaboben...@gmail.com> >> wrote: >> >>> Hi there!
