I have set boot-on on aldo1 I didn't have any success in getting the E bank to have voltage. I turned on a few other voltage regulators as well hoping one of those might be powering the E bank instead, but no luck. I do have voltage on the B bank of gpios and the pins that are exposed do function correctly with the gpioctl command. For output see below. Thanks again for everyone's help. root@generic:~ # sysctl hw.regulator hw.regulator.dc1sw.uvolt: 0 hw.regulator.dc1sw.always_on: 0 hw.regulator.dc1sw.boot_on: 0 hw.regulator.dc1sw.enable_cnt: 0
