Hi BillK, |
37 |
|
38 |
nearly.... ;) |
39 |
Its a Beaglebone Black... |
40 |
Regarding the situation of rtcs it is the same as with the Raspi. |
41 |
|
42 |
Changing between "bein connected to the internet" and "being not" |
43 |
creates a chaos is correctly and incorrectly time stamped files. |
44 |
Previously I got headaches while trying to figure out why certain |
45 |
things (emerging, compiling etc.) does not work properly. |
46 |
Secondly I feel be far more comfortably knowing that I do not |
47 |
have to care about the correct time stamps. |
48 |
Thirdly I dont like such a mess on my system... |
49 |
|
50 |
But the question remains: How can I can introduce the existing |
51 |
of a I2C device (the DS3231) to the system as soon as possible? |
52 |
Since the kernel can be configured to not only care about rtc0 |
53 |
but to use any other rtc, it must be possible to introduce/initiate |
54 |
such a device to the kernel in a pre-filesystem-mount state of |
55 |
booting the system...I simply dont know how... |
56 |
|
57 |
Best regards, |
