Re: Wired Ethernet upload faster than download

Upload can simply go as fast as the router allows. Download requires the flow control since the Pi cannot handle receiving data at the full gigabit rate.

Looks like your router has pause frames turned off.

Re: Multiple Frame buffer beta testers wanted

:D Hi jamesh, Made some further tests yesterday where I was simply running omxplayer in window mode (outputing to DPI or HDMI). As already reported in an earlier post this may result in the other screen going all black, or not working at all (irregular display due to screwed-up timings). What I wan...

Re: Add/Remove SW tool does not have the latest distributions

The RPD is based on the Debian distribution - in effect all we do it add our own desktop (plus a few other bits and pieces), and package it all up. So really, as the fruit says, it's down to Debian to detemine what they include. They are very conservative and have specific rules on what they upgrade...

Re: What value are those parts?

Re: Multiple Frame buffer beta testers wanted

Not sure you can play a HW decoded video over two screens...in fact I think that might be impossible from a HW perspective. You need to specify which screen OMXPlayer outputs to, using the --display option. Takes numbers from 0 to 6 as follows DISPMANX_ID_MAIN_LCD 0 DISPMANX_ID_AUX_LCD 1 DISPMANX_ID...

Often worthwhile checking the date of the last post in a thread to make sure you are not 'necroing' it.

In this case, you might actually have won the prize for the oldest necro - nearly 5 years since the last post.

OK, here's a challenge. Look at the collection of components on the underside of the board, betweemn the memory and the SD card slot. I have to use a magnifier just to make some of them out. Now explain to me how you silkscreen the board to describe those components. It's not really possible for com...

That is odd. It's working here. Can you provide details of the HW you're using (DPI-display (model brand) and HDMI screen). Maybe it's an issue with the reolution. My scrot screenshot shows both desktops, total resolution at my end is 2560x1024. DPI screen is the right one (with mountain wallpaper)...

In general, home routers will have flow ocntrol on by default. A quick search for that router didn't give me any results for flow control. Maybe something to do with pause frames? They are how the flow control is implemented. You can find out if flow ocntrol is on by installing the ethtool package (...
