Rainbow Retro-bit ATARI usb adapter support
Posted by: canadien - 10-19-2017, 04:46 PM - Forum: Support area - No Replies

Hi,

Is it possible to support this adapter :
[Image: atari_to_usb01.jpg?t=1433489911]

Right now only right and down work. It doesn't register left or up.

I've read that the problem are the drivers that have not been updated, hence on the original RetroPie it need a kernel mod to be fully functional: https://www.raspberrypi.org/forums/viewt...t&start=25



I also found those links that can be useful:
https://github.com/robmcmullen/hid-atari-retrobit
https://github.com/msteinbeck/hid-retrobit

Thanks for the heads-up!

  hcitool process consumes 100% CPU
Posted by: greenais - 10-18-2017, 07:27 PM - Forum: Support area - Replies (2)

Hey guys, 
strange thing I noticed in htop:
once I start from ES menu dosbox emulation or ES package install there starts root process which loads one CPU core for ~100%.

Code:
/bin/sh -c while true; do hcitool con | grep -q "$mac" || echo "connect $mac" | blutooth


Terminating it makes no difference on system functionality - both my PS3 BT-connect controllers stay full operational

What is purpose of this process and how could I disable it from unnecessary spawning (as it makes no sense)?


BTW, even if menu background music is switched off in settings the process

Code:
 python bgmusic.py
 
 is still there (I assume it authostarts somewhere) and - which is quite noticeable - it consumes 7-10% of CPU for nothing
Renaming music dir solves the issue)

  dosbox segfaults in 3.0.1
Posted by: greenais - 10-16-2017, 08:35 AM - Forum: Support area - Replies (2)

Hi, 

It seems that dosbox is broken in 3.0.1 - while started from desktop environment it segfaults:

Code:
pi@RetrOrangePi:~$ dosbox
dosbox: /usr/local/lib/libpng17.so.17: no version information available (required by dosbox)
DOSBox version 0.74-ES

Segmentation fault

Forcing dosbox to create a fresh .conf file  doesn't help - segfault again
Fresh ROPI 3.0.1 installation, OP+2E board.

Meanwhile in plain console (no X started, ctrl-F4 at ROPI start) - it works but without any -es graphic acceleration, off cause  Sad
Any ideas, guys?

The template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms.[2] The meaning of the term has evolved to mean a stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system

  PC+ Booting problem
Posted by: OldBikerPete - 09-25-2017, 10:51 AM - Forum: Hardware - No Replies

Hello, I'm a noob. Have only had my Pi's for a couple of days. Have downloaded OS's and utilities from OrangePi main site and am trying to load up an operating system. I've been using Raspberry Pi for a while now, so I know how that gets done but I've struck a problem.
I've burnt three different OS's onto my SD card but they all seemed to produce the same chinese-language Android OS.

My sluggish brain finally decided that I should try to boot the Pi without the SD card in.  Unsurprisingly the card booted to exactly the same OS.

Clearly there is already an Android OS on the Pi's EMMC onboard memory and the boot procedure is ignoring the SD card.
Has anyone seen this problem?  An obvious cause could be that the SD card reader is faulty (the SD card reads/writes just fine in other machines).
Doe anyone have a workaround?

Peter.

  RT8192EU usb-wifi module problem
Posted by: mrxiong - 09-11-2017, 06:23 PM - Forum: Hardware compatibility - Replies (4)

Hello guys! Sorry for disturbing, i have not so much experience with compiling something, but maybe you can show me the right way.

What I have:

I have an OPI PC, an usb-wifi dongle TP-LINK TL-WN823N V2 which have 8192eu chipset (at least google says me that) and ROPi 3.0.1 image running. There is no 8192eu support out of the box, so I tried to compile it by myself.

I performed commands like this:

Code:
git clone https://github.com/Mange/rtl8192eu-linux-driver
cd rtl8192eu-linux-driver
make clean
make ARCH=arm
make install

After that, it's appears 8192eu.ko file within directory :/lib/modules/3.4.113-RetrOrangePi--sun8i/kernel/drivers/net/wireless/. then running
Code:
depmod -ae

Then I type 
Code:
sudo modprobe 8192eu

and got this error:

modprobe: ERROR: could not insert '8192eu': Exec format error

Code:
dmesg | tail

telling me "8192eu: disagrees about version of symbol module_layout".

Some google research make me think that I'm using wrong version of linux headers, but linux headers as I understand are similar to the kernel of ROPi:
Code:
uname -r
3.4.113-RetrOrangePi--sun8i

Code:
ls /usr/src/
linux-headers-3.4.113-sun8i
mt7601-3.0.0.4

What am I doing wrong? Maybe there is any other way to start this dongle? Thanks in advance!

  RetroEngine Sigma - Update from IndieGoGo
Posted by: duke2k7 - 08-21-2017, 07:54 PM - Forum: General Discussion - Replies (1)

So guys,

I've now (with much help from you) fixed up a fresh image of RetrOrangePi fully working with my favourite games, but I did send an email to what I thought was Doyodo yesterday...

Basically, the email read as a genuine customer complaint having found out they had re-marketed a cheap motherboard, patched (very badly) the RetrOrangePi OS and bundled it as a commercial package which isn't allowed and basically how I felt incredibly ripped-off, just like the 7000-odd other customers.

Transpires the email address it came from (although labelled RetroEngine) was actually from Indiegogo, who have emailed me back today telling me that they are beginning an investigation into the whole RetroEngine Sigma farce, especially in respect of them using prohibited software to get people to buy from them.

I imagine that I will soon be getting regular emails from IndieGoGo's legal team....

I didnt forsee me being a crusader for RetrOrangePi when I backed this campaign lol.

Ill keep you all posted.

  Orange Pi Lite Cases
Posted by: duke2k7 - 08-20-2017, 11:21 AM - Forum: Links to DIY sets - No Replies

Guys,

I have a store on Etsy that normally only sells 3d printed props, but I am going to try and design a practical case for the OrangePi Lite that will be cheap to produce but strong enough, with dedicated spaces for fans and heatsinks.

Once I have sorted it I will upload images to here so you can see, and the forum users will get them cheaper than anyone else.

Just a small way of saying thank you for all of the stupid questions I ask lol.

Duke.
