| 10:51.28 | hno | gah.. the TWI controller is not my friend today. |
| 10:53.10 | hno | my attemtps in getting u-boot to talk to the PMU so far only results in failude down to requiring hard power cycle to recover the PMU function at all. Somehow the TWI bus gets jammed putting the TWI controller in an undocumented status 0xf9.. |
| 10:55.17 | mnemoc | ouch |
| 10:55.32 | hno | normal reset do not help. And powering off with power button also do not help it seem, only complete hard poweroff. Don't want to try this on a tablet with soldered battery. |
| 10:56.32 | hno | good thing I have none :P |
| 10:56.38 | mnemoc | :) |
| 10:57.12 | gzamboni | PMU is i2c ? |
| 10:57.25 | gzamboni | didnt check out the datasheet yet |
| 10:58.07 | hno | The PMU is connected via I2C yes. |
| 10:59.17 | gzamboni | today im commanding a raspberry pi, a olimex A13 and lot of other stuff :) |
| 10:59.29 | gzamboni | im happy to move to the arm arch |
| 11:00.26 | gzamboni | why does uboot needs to comunicate with the PMU ? |
| 11:00.40 | hno | Because it needs to configure the voltage levels proper |
