Stumped with what could be wrong?

[johns123]

This is VERY strange! so I am retrying my mister (I have a new USB hub thingy) as I damaged one the other day so had to get a replacement. I am in a very strange situation here. I got a new power thing connected to it (better for my case apparently) I am only initially trying to rebuild before I attempt the case. Now if I plug 2 ports into my power supply (can take a pic explaiing what I mean) I get power to the USB'S but NO HDMI however if I use one port of the power supply I get power to the HDMI but no USB connection. I am absoutely stumped

Your descriptions are too vague to troubleshoot. Pictures of the Splitter and the components are needed

[Stinky]

Have you tried moving the thing?

[johns123]

Up-dated the post with pics I think. I had the USB bridge part not down on the 4 pin slot right but I sorted that just dunno why I having so much trouble here. If I could get rebuilt I would be good to go but........can't

[mike911]

Never seen that power supply before. Maybe try another one? Seems your problem is power related.

[johns123]

Ok this should work instead a video HOPING someone can solve this issue

[johns123]

Right to update a bit here. I have tried the splitter into DE-10 both ends powering on but neither powering on when connected to the USB hub but if I put both ends of splitter say DE-10 and USB hub i'll get USB but no HDMI just into the DE-10 alone i'll get HDMI but no USB

The two boards are powered separately in this setup. My guess is that your power supply isn't sufficient to run both boards at the same time. You might verify look at the amp/wattage. The one that terasic provides for the de-10 is 5V 2A/10 W. That one might not be enough for USB depending upon what devices you attach there. I upgraded to this 5V 4A/20 W supply recommended by My Life in Gaming and its worked great since. You can also find similar upgraded supplies from many Mister vendors.

You might also try connecting through your split power adapter to just one power input or the other, to ensure that its not the splitter at fault.

It's defo not the splitter. Ruled that out (I am on the discord board too) tested it thoroughly and not the splitter. My power supply is this one:

UPDATE: Some sort of SUCCESS! I now have FULL USB and power when I use it on my amazon fire TV however my main TV (Samsung 65 inch QLED) still does not display the HDMI

Try using two separate power supplies to rule out a splitter issue or not having enough power.

Also see if it works disconnecting the USB board to the DE-10. If both power up maybe there is a problem with the bridge.

Also some TVs are picky with the HDMi signal.Make sure you use a default INI with the 720p output and vsync=0 first.

[johns123]

I have all 7 USB ports working so that not a issue. I gonna have a look at my ini file a bit later. I think it's all hunky dory now just these couple of minor issues (TV and hard drive with games on it) but I got a Y cable on the way to deal with the games problem I'll look at the TV later but the amazon fire tv isn't exactly a bad thing for it atm as I probably gonna get my youtube channel going a bit again and the MISTER could play a important part here

[johns123]

So I THOUGHT I was in the clear this morning. Usb-Y cable arrived I thought connect hard disk to the MISTER working again GREAT er................NOPE! Still not being detected YET it works completely fine on my PC I got it connected now with the Y cable

My 128mb ram addon is dead explains a lot of the problems I been having

I think that would explain your C64 problem. I might be wrong but I think the C64 core boots to a black screen if there’s no RAM module.

And other systems I like (amstrad so forth) I'll check pins on everything later just incase but suspect I know only knew I stlll had the ram module today on my dead de-10 plugged it in nope not recognised

You'll never guess what............My new 128MB ram chip arrived. Happy days! then er......................no. Not being detected (and yep it's in the correct place too) ARGH!

[johns123]

It's the DE-10 again Nat (from misterfpga.co.uk) saw my thread responded to me offered to look at the ram chips and yet the slot is dead so frustrating tho as that's needed for cores too

[johns123]

I completely forgot to update my own thread doh So I contacted the seller I bought the DE-10 from actually originally I sent my mister to NAT who tested the ram I bought from him and the original 2.5 I had that is gone dead kaput but he tested my 3.0 ram module all hunky dory the ram slot on my original de-10 well one I had to buy was dead however who I bought it from offered to replace free of charge when I showed them the things that we're going on insert 3.0 ram working de-10 and working fully mister happy days (and NAT was nice enough to do a free case for me too there is some good people on here after all
