Hi all,
I was using the image bone-debian-8.7-lxqt-4gb-armhf-2017-03-19-4gb.img for a GUI application and pins and pwms were configured with config-pin command. This could be done with Cape Universal enabled. But now when I am using the latest images, the /boot/uEnv.txt is changed as per the https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays. And with this image, when I try to run the application it is showing the following error messages: Pin has no cape: P9_13 P9_24 pinmux file not found! Pin has no cape: P9_24 P9_26 pinmux file not found! Pin has no cape: P9_26 P9_17 pinmux file not found! Pin has no cape: P9_17 Also in my code, I was accessing files from folders like /sys/class/pwm/pwmchip2. But these folders are not there now. I think, if we are changing to u-boot overlays, then we have to change our source code. So it is better to stick to the old kernel overlays. As per the web page https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays, I tried to enable Cape Universal by disabling *"enable_uboot_overlays=1" in /boot/uEnv.txt.* But still it is not working *. * *Now I used the the image bone-debian-9.1-lxqt-armhf-2017-08-31-4gb.img and the uEnv.txt is as shown below.* *#Docs: http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0uname_r=4.9.45-ti-r57#uuid=#dtb=###U-Boot Overlays######Documentation: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays###Master Enable#enable_uboot_overlays=1######Overide capes with eeprom#uboot_overlay_addr0=/lib/firmware/<file0>.dtbo#uboot_overlay_addr1=/lib/firmware/<file1>.dtbo#uboot_overlay_addr2=/lib/firmware/<file2>.dtbo#uboot_overlay_addr3=/lib/firmware/<file3>.dtbo######Additional custom capes#uboot_overlay_addr4=/lib/firmware/<file4>.dtbo#uboot_overlay_addr5=/lib/firmware/<file5>.dtbo#uboot_overlay_addr6=/lib/firmware/<file6>.dtbo#uboot_overlay_addr7=/lib/firmware/<file7>.dtbo######Custom Cape#dtb_overlay=/lib/firmware/<file8>.dtbo######Disable auto loading of virtual capes (emmc/video/wireless/adc)#disable_uboot_overlay_emmc=1#disable_uboot_overlay_video=1#disable_uboot_overlay_audio=1#disable_uboot_overlay_wireless=1#disable_uboot_overlay_adc=1* *######PRUSS OPTIONS###pru_rproc (4.4.x-ti kernel)#uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-4-TI-00A0.dtbo###pru_uio (4.4.x-ti & mainline/bone kernel)uboot_overlay_pru=/lib/firmware/AM335X-PRU-UIO-00A0.dtbo######Cape Universal Enable#enable_uboot_cape_universal=1######Debug: disable uboot autoload of Cape#disable_uboot_overlay_addr0=1#disable_uboot_overlay_addr1=1#disable_uboot_overlay_addr2=1#disable_uboot_overlay_addr3=1######U-Boot fdt tweaks...#uboot_fdt_buffer=0x60000###U-Boot Overlays####cmdline=coherent_pool=1M net.ifnames=0 quietcmdline=coherent_pool=1M net.ifnames=0 quiet cape_universal=enable#In the event of edid real failures, uncomment this next line:#cmdline=coherent_pool=1M net.ifnames=0 quiet video=HDMI-A-1:1024x768@60e##Example v3.8.x#cape_disable=capemgr.disable_partno=#cape_enable=capemgr.enable_partno=##Example v4.1.x#cape_disable=bone_capemgr.disable_partno=#cape_enable=bone_capemgr.enable_partno=##enable Generic eMMC Flasher:##make sure, these tools are installed: dosfstools rsync#cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh* *And for this case * *sudo /opt/scripts/tools/version.sh is as follows* *root@beaglebone:~# sudo /opt/scripts/tools/version.shgit:/opt/scripts/:[288a143ff1aaeb8f6df5c328b60b6d220082cd47]eeprom:[A335BNLT000C1827BBBG1897]model:[TI_AM335x_BeagleBone_Black]dogtag:[BeagleBoard.org Debian Image 2017-08-31]bootloader:[microSD-(push-button)]:[/dev/mmcblk0]:[U-Boot 2018.09-00002-gd5b4c4b656]:[location: dd MBR]bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2016.03-00001-gd12d09f]:[location: dd MBR]kernel:[4.9.45-ti-r57]nodejs:[v6.15.0]pkg check: to individually upgrade run: [sudo apt install --only-upgrade <pkg>]pkg:[bb-cape-overlays]:[4.4.20181120.0-0rcnee0~stretch+20181120]pkg:[bb-wl18xx-firmware]:[1.20180517-0rcnee0~stretch+20180517]pkg:[kmod]:[23-2rcnee1~stretch+20171005]pkg:[roboticscape]:[0.4.4-git20180608.0-0rcnee0~stretch+20180609]:[GOT_REPLACED_BY_NEXT]WARNING:pkg:[librobotcontrol]:[NOT_INSTALLED]pkg:[firmware-ti-connectivity]:[20170823-1rcnee1~stretch+20180328]groups:[debian : debian adm kmem dialout cdrom floppy audio dip video plugdev users systemd-journal i2c bluetooth netdev cloud9ide gpio pwm admin spi tisdk weston-launch xenomai]cmdline:[console=ttyO0,115200n8 root=/dev/mmcblk0p1 ro rootfstype=ext4 rootwait coherent_pool=1M net.ifnames=0 quiet cape_universal=enable]dmesg | grep pinctrl-single[ 2.305156] pinctrl-single 44e10800.pinmux: 142 pins at pa f9e10800 size 568dmesg | grep gpio-of-helperroot@beaglebone:~# * Still I am not able to use config-pin command and so I think Cape Universal is not enabled.
