kernel unable to access tmp421 and ds1307 #12
Comments
Thanks for testing. I assume this is on Palmetto as well? Can you reproduce in Qemu? We want these opened as kernel issues. We need the kernel handle poorly configured hardware. |
The previous u-boot was adding an I2C driver which was doing a reset of the I2C controller. Should we add such a reset in the machine setup in the kernel ? |
@shenki - Do you want this moved to kernel? You can move it with 'zenhub' (or I can do it for you). |
Yes, lets move this to the kernel |
Issue moved to openbmc/linux #96 via ZenHub |

Similar to #11, this seems to be a hangup for the kernel due to the move from 2013.07 to 2016.05.
On bmc boot the rtc and tmp421 sensor cannot be accessed:
rtc-ds1307: probe of 0-0068 failed with error -5
tmp421 2-004c: Could not read configuration register (-5)
tmp421: probe of 2-004c failed with error -5
