Yes, directly via i2c bus from userspace. You need i2cget utility and run it as root. Look at shadowjk bq27200.sh information script at http://enivax.net/jk/n900/bq27200.sh Very thanks. That script indicates temperature. Interesting, what means Cycle Count since Learning: 29 Total Cycle Count since last full reset: 134?

There are no HDD in the device :) Battery charge/discharge cycles. The battery fuel gauge chip will count the capacity from full charge down to empty, and learn the battery's capacity. Due to the default settings, it takes about 4-5 such learning cycles before it learns the capacity correctly the first time. It's also actually a bit rare to have the chip learn capacity normally, because bme shuts down device before the threshold at which the chip considers the battery empty. In any case, 29 means 29 charge/discharge cycles since the last cycle during which it could learn the battery capacity. 134 total charge/discharge cycles. It gets reset if the battery is removed for a longer time. ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

You cannot run BME and bq27x00_battery together. So you can load bq driver when BME is stopped and before starting BME driver must be unloaded. Thank you for that information. It is very pitty that that issue was not described on that wiki-page. As I can see after removing the bq27x00_battery module my device become again able to reboot (earlier the command `reboot` from terminal or using buttong in its menu only shut down my device not reboot - and I didn't know why; now it seems that it was from loading that module). But if bq27x00_battery and BME cannot run together how can my device was able to start? There is problem that BME and bq driver want to talking to bq chip via i2c bus. For security reason this cannot be allowed, but it is possible to start BME and then load driver (in this order). This is bug in kernel and this situation is DANGEROUS!!! So normal usage is: stop BME, load bq driver then remove bq driver and start BME. h-e-n gui is stopping BME, so when h-e-n is open you can load bq driver, but do not forget to unload it before closing h-e-n. automounting FS in usb hostmode (without pressing mount button or mounting via terminal) will work if you update kernel-power to v50 and ke-recv to last version.
