RE: Onion Omega2 LTE - coming soon to Crowd Supply
I didn't back the oboo. I pulled out for some reason that I forget now. Perhaps it was the closed source aspects, can't really remember. Nevertheless, it is a pity that it doesn't seem to be getting the attention of the other Onion products. Or perhaps it is, but the closedness of it means no volunteer input to widen the support base.
Back OT, yup, the lack of emmc means we are back to the fiddly external sd storage external boot options. Perhaps there was insufficient space on the board to house the chip, although it looks like there's plenty underneath.
I guess we will have to wait on the data sheet (or an official post here - It annoys me that the Crowd Supply platform doesn't enable interactive questions on their projects) regarding whether the USB-C is host or not and whether there is any impact regarding usb flashing for recoveries. I must admit, I use that functionality a lot! I doubt I'd back this if it was removed, unless there's an alternative bare bones recovery option offer that doesn't require an ethernet expansion.
Onion Omega2 LTE - coming soon to Crowd Supply
Didn't see any mention of this here yet.
Found this in my mailbox this morning: Onion Omega2 LTE A 4G LTE and Wi-Fi connected Linux dev board with GNSS global positioning
So this looks to be the answer to the long awaited (for me anyway) cellular option.
RE: Questions before I buy
Unlike some very popular boards (eg RPi) I don't think there are many (if any? - others can shout at me if I'm wrong ;-) 3rd party commercial 'hats'/expansion boards. Some contributors have built their own expansions for their own needs (browse through the Projects forum to see what others are doing), but as for commercial boards specifically targeted at the Onion devices, I believe that the Onion store will be your likely source.
Having said that, the point of the devices (IMHO) are to spark your own ingenuity and get you to explore and build your own projects and if that means taking it to the board level, then that is what you should do, as have others. I see the commercial expansions from Onion as tools for prototyping and in some cases, all that is necessary to realise your own project. But the flexibility is there for you to do with them as you choose - or not even use them at all and instead design your own.
RE: How to estimate actual flash memory wear caused by SQLite3?
These are all good questions and the answers definitely should be of interested to everyone here.
RE: OpenWRT 18.06 no have some packages
And I really did not find the OpenWrt 18.06 'php7-mod-mcrypt' package (2019-03-11).
See also: OpenWrt Packages
I was interested in uncovering where it went and found this in the OpenWrt 18.06 php7 package changelogs for the php7.2.0 commit:
Also drop mcrypt module as it's deprecated.
So @Adrian-Aguirre I suppose you will have to review why it was deprecated and what the current best practises are around using the mcrypt functionality.
Deprecated features in PHP 7.1.x
Migrating from PHP 7.1.x to PHP 7.2.x -> Other changes
RE: Omega RTC Integration
IIRC, the standard RTC package implements an init script which will read the data from the RTC device on boot and set the clock accordingly.
On shutdown it updates the RTC device with the current clock value.
In between those states, if a network connection is established, the Omega will query NTP servers and sync the clock with that.
So, as long as you build your firmware with the requisite packages (the one with the driver for your RTC device and the standard RTC package together with any dependencies either require) and ensure that the RTC device is accessible during boot up, your needs should be accommodated.
PowerDock 2 - Discharge / Charge
I've been logging my PD2 battery level over the last couple of days, as reported by the
/usr/bin/power-dock2utility and observed an interesting discharge/charge trend:
Voltage discharges to around 4v and then charges up to 4.12v repeatedly.
Has anyone else observed the same thing?
Is this normal?
I would assume that this is handled by the battery management chip. Or am I wrong?
Is it odd that this interests me? ;-D
