Aunty Entity

Alright then, we're at the solution, and as suggested earlier it is infact, a overworked USB port. To get there I tried swapping out the camera, the hub, cooling the CPU briefly, had it down to 25c all to no avail. Then gave in, just bunged the cam into the USB port and the network back into the RJ45 rather than USB Wifi. I'm still surprised by... how much the system as an entity lags when the USB port is busy that 2 devices is enough to bury it. that at times it appears to all work, then just slows to a crawl over time. Thanks for all your time, A

Its now been powered down for 24hrs and I've come back to it, powered up and its running like a train again? <boggle> So far no other changes. But I have done another monitor -u to see if there's anything obvious going on in there. Still suspect heat and throttling.. given the symptoms...there's a 5deg difference from when it was going slow. http://ix.io/2ke1

Thanks for looking Guido. You're doing well identifying that lot, from the list I can hardly tell you whats what. What has me somewhat tossed by this state of affairs is... in a previous location, this device ran like the wind for months, but I had bad power in the location and I'd have to come back and reset it frequently. Having moved it a new location with a different power supply for four days solid it again ran like the wind.. until today.. Where its now running like it has the handbrake on. I s'pose the wifi is another wrinkle and I could reset the router too... but wasn't expecting it to be an issue. You're right about only 1USB port, so there is a hub which has the card reader onboard, the camera and the wifi dongle. Only the camer and wifi are really in use, although I guess the other bits still reserve their right to use it. Hmmm I s'pose where it is now located I could probably wire it into the regular network and see if that makes a difference also. In the past the RT2780 has been a flawless performer, if I have to hand an unknown off the network its usually my goto piece. I'm about to take 5, so I'll come back and have another look at this later, and give a heads up on how everything is going. Thanks, A

Ok, might be my bad, I had a much newer R1 image, not the One, I thought I'd put a new image on it.. I'll see what happens.

uh?

I'm running a web cam on a OrangePiOne. For the last four days its been performing adequately, at least as well as the RaspiPiZero. At the moment though its suddenly decided to become a snail... slower than paint drying or melting blanc mange. So here I am looking for pointers. I don't have a lot of detail, but what I have follows. I'm using mjpg-streamer to handle the webcam. In the past this has been rock solid without issue, at this point I assume its not the problem in itself.

That was ttyS1 not 0 that cam up. Looks like it was an easy fix. Leads me to a new question though, I need to feed this through an RS232 serial port to a legacy system. The adapter/converter I have isn't doing the job, its just screaming rubbish. Does anyone have a line on something that will do the job properly? The one I have now was nominally for an Arduino if that makes a difference. This isn't the first one I've tried either... :/ Thanks, A

Promising, I've got loopback on ttyS0 now... be nice if there was some EASY to find document that had this in it... now let me see if I can get anything resembling data to my terminal Thanks so far

Welcome to Armbian Bionic with Linux 5.4.20-sunxi This is the thing I have installed... I'm trying to use the serial ports out of the GPIO header, nominally pins 8 and 10 which depending on what you read maybe ttyS1 or ttyS3. Out of the box whatever they are they're not available. After much googling, I've seen stuff about FEX and DTS none of which mean much to me, I'm guessing Bionic doesn't use FEX as there's no sign of .FEX or .BIN files in the /boot directory. The default state seems to pump garbage out the tx line whatever its doing. Minicom promises to talk to any ttyS? I give it, but theres no answer on loopback, And that's all I have. All pointers gratefully received. I never did get to the bottom of just what DTS is or how to configure it. Regards, A

I agree.. I have a new set of options to try on pppd today, I'll come back to slip for another look after that. Aside from it being slip, I'm not sure it really gets me much closer. I'd prefer to wire it in, I already have a handful of Opi's laying around doing nothing. My hit miss rate with esp is about 50%, not terribly good. A

You're pretty much right all round there. The IIgs is the client, it is marinetti that I'm trying to use. However its giving me nothing but grief, so I was considering trying SLIP. Ahh yes there is wifi, and I have played with the esp boards before. What I was wanting PPP for though, was routing what native tcp applications there are for the GS out into the real world. And local networking NFS etc. Its more a convenience thing than a speed thing, give the best I'll get it 57.6k on a side note, I never did like marinetti much... always used to fall over for me :/

Out of interest, does anyone know if there's a SLIP package in existance still? I have an antique Apple IIgs which is having trouble with PPP and want to try it on SLIP which it used to do fairly happily. But I can't find any reference to one, just looking for confirmation though. Regards, A
