This wait for network to start jivelite may be problamatic. I know there are going to be a fair number of people that will want to run with the embedded LMS and have no network connection at all. Their only interface to the system will be with jivelite. That is going to make it difficult for those people.
On the issue of RTC and time, we have to be careful about this, the wandboard module does not allow for a battery backed up RTC. The EDM spec has a pin for this but the wandboard module does not connect anything to this. The RTC power pin of the processor is directly connected to a regulator on the module, there is no way to change this without doing surgery on the module. Thus upon a powerup boot the clock is going to be reset, so it has to be set externally, either NTP or some other means. For those running without a network connection the only way they have to set the time is through jivelite, if jivelite doesn't start until the time is set they are in a bit of a catch22. The only way I have been able to come up with an RTC that runs during power off is to put one on the carrier with a supercap or some such. The processor could then query the carrier RTC over I2C at boot time to set IT'S RTC. Of course it would have to make sure it set the carrier RTC when updating the time from NTP or manually. Currently CSP1 doesn't have an RTC, but it's not too hard to add one. I could even do a little board that has an RTC and supercap that plugs into an appropriate IO connector on the wandboard to test this out.
