Hi, parts of of my gta04 seem to need a sleeping pill. They seem to be sometimes active despite not being used. What I have done: booted my 4.4 kernel via uboot commandline. Set init=/bin/bash loaded w2sg0004 current consumption is at 64mA. but...
I mounted debugfs root@(none):/mnt# cat pm_debug/time usbhost_pwrdm (ON),OFF:0,RET:209739227320,INA:0,ON:15410675024 sgx_pwrdm (OFF),OFF:222150573730,RET:0,INA:0,ON:2999237061 core_pwrdm (ON),OFF:0,RET:0,INA:0,ON:225149749756 per_pwrdm (ON),OFF:0,RET:0,INA:0,ON:225149627686 dss_pwrdm (ON),OFF:0,RET:215521057110,INA:0,ON:9628448505 cam_pwrdm (RET),OFF:0,RET:221982666016,INA:0,ON:3166809082 neon_pwrdm (ON),OFF:0,RET:215551147441,INA:0,ON:9598266621 mpu_pwrdm (ON),OFF:0,RET:215558868400,INA:0,ON:9590454110 iva2_pwrdm (RET),OFF:0,RET:222150726318,INA:0,ON:2998565674 For my taste there is too much on even though I am at 64mA. Especially why is usbhost and dss on? If I am reading the table correctly it is on for some time, then in some kind of standby (RET). No usb modules are loaded. Lcd was not used in uboot. Maybe the current consumption can be lowered if some of these find a better sleep. Regards, Andreas
