Quick and Dirty userspace testing of regulator with virtual consumer

-
Writing a driver for a new regulator is usually fun, until you need to test the darned thing. Many of the users of the regulator is probably not yet ready in an development environment and need to test cant wait. I had recently a similar situation and found CONFIG_REGULATOR_VIRTUAL_CONSUMER You'd probably register and provide and regulator supply, but without a driver using it in a controlled environment (read shell script or so), it is hard to poke holes completely into your driver. Steps are rather simple. Assumption - you already have a regulator registered in the system and you are aware of the regulator name - You can also figure out it's name by the following (an example from 3.9-rc8 on Beagle-XM): # head /sys/class/regulator/*/name ==> /sys/class/regulator/regulator.0/name /sys/class/regulator/regulator.1/name /sys/class/regulator/regulator.2/name /sys/class/regulator/regulator.3/name /sys/class/regulator/regulator.4/name /sys/class/regulator/regulator.5/...

Steps summary: 1. first shutdown the board. 2. run 'sudo recover_beagle.sh /dev/ttyUSB0' in a terminal -> you need super user permissions(sudo permissions) to run this script. 3. Keep the pushbutton S1pressed while powering on the board -> there are two white push button switches, use the one closer to the edge of the board NOTE: if your nand is com...

The post is a derivative of the omapzoom wiki page . Disclaimer: my mastery of the wiki tags are dismal.. apologies... some day i hope to have time to post it here Many new developers have been stumped when they need to use git-send-email in corporate environment – usually, if not as a norm, ms exchange servers form the backbone of such an email server system. This page was written based on one of such requirements. To get started, we shall consider common scenarios: a) Setting up a mail forwarding system with postfix on ubuntu b) Setting up a mail forwarding system on a fedora machine c) Using msmtp for using gmail a. to send a patch using a gmail ID b. to send a patch using your corporate ID but through gmail Postfix on Ubuntu – mail forwarding For setting up postfix, you need: a) A mail relay server which will allow your machine to talk to it -> speak to your IT representatives/ other developers sitting next to you b) Super user privileges on the machine you are working on. Step...
