Hi,
I can't create SPIDEVx character devices in /dev. I recompiled my BB-SPI0-00A0.dts with the released dtc compiler. In the uEnv.txt file, I tried moving the BB-SPI0-00A0.dtbo to cape_enable=bone_capemgr.enable_partno=BB-KATS,BB-SPI0 and got the following error "48030000.spi: chipselect 0 already in use". How do I determine what is assigned to the SPI0 CS pin? What default or base device tree binary does the U-Boot enabled uEnv.txt file use? PS: I did try the generic BB-SPIDEV0 overlay and got the same error. sudo /opt/scripts/tools/version.sh git:/opt/scripts/:[23650994e41b16bcf78253cde7d35a93664beeef] eeprom:[A335BNLT00C03016BBBK0E44] model:[TI_AM335x_BeagleBone_Black] dogtag:[BeagleBoard.org Debian Image 2017-10-10] bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2017.09-00002-g0f3f1c7907] kernel:[4.4.91-ti-r133] nodejs:[v6.12.0] uboot_overlay_options:[enable_uboot_overlays=1] uboot_overlay_options:[uboot_overlay_addr4=/lib/firmware/BB-KATS-00A0.dtbo] uboot_overlay_options:[uboot_overlay_addr5=/lib/firmware/BB-SPI0-00A0.dtbo] uboot_overlay_options:[disable_uboot_overlay_video=1] uboot_overlay_options:[disable_uboot_overlay_audio=1] uboot_overlay_options:[disable_uboot_overlay_wireless=1] uboot_overlay_options:[disable_uboot_overlay_adc=1] uboot_overlay_options:[uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-4-TI-00A0.dtbo] uboot_overlay_options:[enable_uboot_cape_universal=1] pkg:[bb-cape-overlays]:[4.4.20171126.0-0rcnee1~stretch+20171126] pkg:[bb-wl18xx-firmware]:[1.20170829-0rcnee1~stretch+20170829] pkg:[firmware-ti-connectivity]:[20170823-1rcnee0~stretch+20170830] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
