Hi Robert, I have the same issue of no available 1000MHz. I have tried updating the eeprom as instructed in this post but no difference.
The output of version.sh is: git:/opt/scripts/:[73593ebe3b7d3cc381eeb502d45ccb33a6ec5e78] eeprom:[A335BNLTBWA50000BBWG*] model:[TI_AM335x_BeagleBone_Black_Wireless] dogtag:[BeagleBoard.org Debian Image 2018-08-30] bootloader:[microSD-(push-button)]:[/dev/mmcblk0]:[U-Boot 2018.03-00002-gac9cce7c6a]:[location: dd MBR] bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2017.01-00006-g55e748eda0]:[location: dd MBR] kernel:[4.14.69-ti-r75] nodejs:[v6.14.4] uboot_overlay_options:[enable_uboot_overlays=1] uboot_overlay_options:[uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-14-TI-00A0.dtbo] uboot_overlay_options:[enable_uboot_cape_universal=1] pkg check: to individually upgrade run: [sudo apt install --only-upgrade <pkg>] pkg:[bb-cape-overlays]:[4.4.20180914.0-0rcnee0~stretch+20180914] pkg:[bb-wl18xx-firmware]:[1.20180517-0rcnee0~stretch+20180517] pkg:[kmod]:[23-2rcnee1~stretch+20171005] pkg:[librobotcontrol]:[1.0.2-git20180829.0-0rcnee0~stretch+20180830] 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 eqep admin spi tisdk weston-launch xenomai] cmdline:[console=ttyO0,115200n8 root=/dev/mmcblk0p1 ro rootfstype=ext4 rootwait coherent_pool=1M net.ifnames=0 quiet] dmesg | grep pinctrl-single [ 1.043241] pinctrl-single 44e10800.pinmux: 142 pins at pa f9e10800 size 568 dmesg | grep gpio-of-helper [ 1.044810] gpio-of-helper ocp:cape-universal: ready END Have you any suggestions?
