PcDuino8 Uno doesn't work at all.

Recommended Posts

Guest shawn

I've tried every combination of Os for this board and none of them work. There is like five led's that light up and nothing shows up. The rx tx leds light up for a second then shutoff for a few seconds then back on. No blinking, no display no nothing. I've been playing with this board for several months and have never had any luck whatsoever. Is the board shit or what. There's very little info or anything for this board. 

  I can boot up a new Pi in about 3 mins, I can program and use any type of arduino yet this thing nothing. I'm thinking I should have sent this thing back while I had the chance.

 

    Any help, tips or pointers would be greatly appreciated.

On one of my boards, the micro usb jack was busted inside, so the micro usb cable wasn't making a connection unless I held the cable in the exact right place :/ On that board I was able to power it via the OTG port though. Which means that I can't use the regular USB port though, because they're too close together... >.<

 

But yeah, none of the boards I've tried have any form of video out, and a number of other issues I'm trying to sort out. I can SSH into them though...

I don't know about these boards. I have a Linknode D1 with esp8266 that seems to work ok. i have the PcDuino 8 that doesnt work at all and Linksprite relay shield and a  GPRS/GSM Linksprite board that dont work worth a shit either. I think i'll be swticking with arduino boards from now on. You can't get any help and what there is is slim to none.

Me neither, I've been very successful with all other boards except anything linksprite and of course the orange pi's. Nothing works on any linksprite board I've used except for a linknode d1 with the esp8266 on board. It works ok but have problems with it. I own 6 different linksprite products and wish I could return them

Yeah, I agree there...part of me wants to try to sell my PCDuino's on eBay, but I don't want someone to buy them thinking they'll be a cool toy only to be stuck with the dud that they are. I've spent quite a few hours trying to figure out if I can do a custom-build of Debian or something along those lines to try to get them usable, but nobody seems to support the H8 yet.

 

I'm very curious though -- it seems like some folks on the forum here have gotten them to work somewhat -- but how??

these boards are powered insufficiently and most of the time its because of the power supply being used.  I ran it using a 5v 2.1a constantly for months and it had video out.  make sure your tv/monitor is setup for 720 as this board wont go 1080 very well that is another issue with them.  this board is complete shit and i am surprised mine has worked so well.  also as a side note after continued use i fried a micro usb cable supplying power from the wall charger.

I'd thought that might be it, so I tried the charger from my S5 (rated for 2A) and a beefy microUSB cable, but it didn't make a difference :/ Just have the one monitor and TV to try with, so it could be a compatibility issue I guess, will maybe try to hook up to a friend's house sometime if I feel that motivated...

Ok, I finally got video working. I ended up having to do a different display (the output is apparently hard-coded for 720p at 50hz??,) different microsd cable, and found that I couldn't have the display or keyboard hooked up during first boot -- the board would hang indefinitely. But now I'm able to at least view the desktop on a TV.

 

Going to try to dig through some things to figure out how to fix the display resolution hopefully.
