[Robert Steinman]

Hi @Hqnicolas first of all, thanks for all yours and other efforts on this project. I had an eye on it a few months back but only this week did I dig out my two boxes..

 

A few questions for you if you don't mind answering?

 

I have two boxes, 2GB version I was using for development (Android image) and then full fledged 8GB version. Now, because the boxes were in storage for a year or two I thought I had the 4GB and 8GB version, do you happen to have somewhere the Bootloader image for the 2GB model? I've done a google but can only find the 4 and 8GB version. I was experimenting with Armbian and kinda bloated the image so I'll start from scratch. 
 

I went ahead and flashed Armbian on both now without issues, however, I've noticed the Wifi is quite slow on it - around 120-240KB/s download and ping to `1.1.1.1` gives around 30 - 300ms, I've had `top` going at the same time and don't see any high CPU utilization. The Wifi driver is something like `bcmrfm` or alike. Is this normal?

 

I've got my 2GB version hooked up to serial out. I do remember seeing an output in plain English however I can't remember the settings, would you be able to tell me? I've tried the common baud rates with Minicom but no matter what I do I just get a garbled output. 

 

The link from previous messages for the SDCard holder is now invalid, could you point me to one that will fit nicely on the board?

Finally, from your last post, I see you got the front display displaying data, could you point me in the right direction to code for this? Either C++ or Python will do. I do plan on a monitor for eth, wifi and with time + load + temp possibly.

 

Thanks,
Robert.

thanks for getting in touch, looks like you're the first one with these 2gb boxes

I think the memory trainer for 4gb and 2gb are the same, do stress and performance tests, if crash occurs you really need a new memory trainer for 2gb, you can find an example of memory trainer on this @mvpwar logs

do not use third party images, not even mine, always get the official ones

This is really an unknown, I bought 4 boxes of this model in 2022, since then there have been changes in the manufacturer's list of materials, the wifi driver is not configured for a reason, the reason is that the wifi has changed several times, you can install the 2022 driver or you can look for users @dfahren who have a different chip here, or even detect a new chip unknown to everyone

For this question we need to ask @Jean-Francois Lessard he was in contact with this drivers for a while. (Link)
this display will be enabled on kernel 6.18+ if you want to mess with experimental images follow this
I only got involved in this because there were many interested users, I wasn't one of them

@Hqnicolas I'm a bit late because I have overlooked your request for testing.
Now I can confirm that the AuxDisplay works correctly with my H96_tvbox_3566 (with AIC 8800 wlan chip).
Thank you for your effort.

@Hqnicolas Thanks for your response and apologies being so slow to reply busy IRL and then I forgot I used Google to sign up to this site.... yeah...

 

Okay thanks - I thought it would just be a changing of timing so to speak on x86. In this case if I plan to develop for something I also go for the lowest variant of it, ofc, at this time both were Android. Rather code closer to the "metal" than bringing a whole web browser in to say "hello world"

 

The images came from a link on this thread; either yourself or another member. 

 

Yeah I noticed a certain lag on the ethernet with 1GBit connection -- it has all the resources available yet it pings hard and downloads fluctuate. My plans for this Armbian is WiFi Repeater (router is broadcom and no Open- or DD-WRT alternative) to relay the signal. I don't want mesh, I don't need a TPLink account. The box will provide some services to Orange/Raspberry Pi systems.

 

Right. I'm against AI  So last thing I'd do. A link was provided but as I said expired. I'm sure there's differences in SDCard holders so didn't want to order two of the wrong type!

 

Ah obrigado! I think your link may have solved it. I'll look in to it a bit in the future. Amazing how an Firestick turned me to Chinese  TV boxes which are quite capable once you get rid of the Spyware.

 

What I will say is, I think these boxes may have poor solder joints on the WiFi sub board, was hoping it was a misconfiguration my 8G model no longer recognizes the Wifi board, when I get the SD card holders I'll reflow it ad see. dmesg, lsusb, lspci know nothing of it. my 2G box the WiFi is fine.
