So the data is there, how can i get this data showing in my dashboard plugin? RE: Raspberry Pi 4 released! - Didier B - 2019-09-28 Hi everybody, I was so impressed by the "à la carte" way to install and maintain OP 2.0, Congratulations ! Since 2 weeks now I could put my hands on a Pi4 4 GB, I made an USB SSD install using this turorial, describing the 'old school' way, necessary due to Pi4 premature launch, and consequential under achieved development, (Use of an SD card for the /boot directory, while the /Root directory is installed on the USB SSD - take care, some have been life banned from the organisation's forums as they protested eagerly against that ) ! At first I experienced some instability issues (vanishing desktop, freezing, openCPN crashes), all this was due to a bad quality USB extension 'cord', I ordered new ones, and temporarily replaced it with a good, thick, short (1') USB2.0 cord, It is now 100% stable and starts like a rocket : 35 s to boot up, 'System Check' included ! I also noticed that OpenCPN conf file does no longer get lost, as It used to do with either my Pi 2, 3 or 3B+, though all is not clear in OCPN5.5 configuration, see Cruiser's forum Whatsoever, we do need a place to report & discuss supposed anomalies (e.g. I can't get OpenCPN to launch automatically, is it due to state of dev., or to my configuration, or what ?) (***) Globally OP 2 is working like a charm, I started the process to box it up to install it in the nav station ! (OK Sailoog, I'll keep OP 1.2 for a while too) ! Merci Braz, Thank you, Gracias, oui, un SUPER MERCI à toutes et tous pour tout cela ! (***) EDIT 2019/10/06 : after the morning's upgrade, I had the good surprise to see OpenCPN start automatically ! RE: Raspberry Pi 4 released! - rastam4n - 2019-09-28 Lol. Didier I did the same thing and ended up using the same method. RE: Raspberry Pi 4 released! - abarrow - 2019-09-28 Didier, I did the exact same process to get OP2 up and running on my new RPI4. I used an SSD adapter that was designed for RPI3, so the little short USB jumper is in the wrong place, but that was quickly solved by a male-male USB cable. Openplotter installed great on top of the full Buster image. I'm impressed at how fast OpenCPN runs. However, I am finding that it is freezing from time to time. I've played around with GPU and video memory and it seems to have lessened the problem, but I still occasionally get freezes. One question, is anyone else using MBTiles charts with OpenCPN? Since they require OpenGL, I'm thinking that might be the source of my freezes. I really, really like MBTiles charts - they provide more color, are smaller, and are very easy to create with SASPlanet. Much appreciation to Sailoog and the whole team for their hard work. You guys rock! Andy RE: Raspberry Pi 4 released! - Sailoog - 2019-09-30 Thanks guys, we go as faster as we can. e-sailing is working right now on openplotter-serial and I am working on openplotter-can. After both packages are done we will publish the first img and NOOBS files for translators and a first serious debugging round: http://forum.openmarine.net/showthread.php?tid=1992&pid=10280#pid10280 Please use the debug forum to report any issue but be sure you add [OP2] to the subject or something similar. Be careful! - abarrow - 2019-10-03 Well, it looks like after just a few weeks with my new RPI4, it's dead. I had it set up with OP2, and it was using an SSD for root folder. It was sitting on the desk, running fine, and we discovered we had a leak with rain coming in the window. To get the RPI out of the way, I just switched off the power without shutting down. The RPI never got wet. Now, a couple of days later, I tried to bring it back up. Nothing. Red light, test points on the board show proper voltage, but no green light and apparently no attempts to boot at all. I followed the instructions for re-installing the bootloader, but nothing happened. It's just not attempting to read the SD card at all. So, I'm out $65 I guess. It was a 4GB version and working really well. This is a very interesting issue with regards to putting this new RPI on my boat. Of course, I always try to make sure that I properly shut down my OpenPlotter system before I turn everything off, but occasionally "stuff" happens. I hope this one incident isn't an indication of the sensitivity of the new RPI4 to accidental power loss. I did read on the main Raspberry Pi forum that the RPI4 is different - is uses onboard EEPROM to store a bootloader, and it can become corrupted. I have no way of knowing that this might be my problem, but as I said, I did follow their instructions for re-installing the bootloader with no success. For the moment, back to my RPI3+! Be careful out there on the bleeding edge, kids. RE: Be careful! - rastam4n - 2019-10-03 (2019-10-03, 04:59 PM)abarrow Wrote: Well, it looks like after just a few weeks with my new RPI4, it's dead. Before you throw in the towel maybe try reloading the OS on a new sd card from scratch. I have had SD cards fail and had similar results. RE: Raspberry Pi 4 released! - abarrow - 2019-10-03 Thanks for that. The issue right now is that the green light isn't even flickering, which it would be doing if the PI was reading the SD card. I definitely plan to give it a try, but all indications are that if the green light isn't flashing at all, the PI is dead. RE: Raspberry Pi 4 released! - abarrow - 2019-10-03 Well, as we used to say in the Ozarks, "I'll be jiggered!". I created a new SD card, put it in and powered up, and nothing happened. Then, I thought, "Well, perhaps there's a cold solder joint somewhere", so I grabbed either end of the RPI and gently twisted, thinking just that slight stress might reconnect a cold joint. It actually started to boot! Crazy! I'm going to keep this one for testing here at home - it might be a while before I trust this particular RPI to navigation on my boat. RE: Raspberry Pi 4 released! - rastam4n - 2019-10-03 Hah! thats great! |
