[SOLVED] Can I install Gem software to an existing build?

Post by Robochris » Thu Mar 14, 2019 6:33 pm

Or does it have to be a clean install?

I ask because I used a non-W pi because I have several laying around that arent being used and the sd card is easy to get to in the gem and I could pop the sd into a W and make any edits I needed.

I cant get this to connect to my wifi for anything.
I tried the updated wpa_supplicant.conf.
keyboards and usb controllers are unresponsive when I plug them in and use hdmi on my tv..

So can I just set up a vanilla retropie set up, add everything I need to, then add Kites mods to the software?
If so, How do I go about doing that?

An alternative is to get a USB MICRO OTG cable and plug it into the port at the top, then you can connect USB wifi adapters to it. You can get some neat micro USB hubs, which work great and because they have also a micro USB IN, you can 'power the hub' which is needed for some power hungry wifi adapters (because the Gem will output battery voltage to it, not 5v which some adapters might need, hence the powered micro usb hub) : https://www.aliexpress.com/item/OTG-3-4 ... 25063.html

Or, use something like Paragon EXTFS to mount the ext portion of the SD

So what’s the difference between an otg adapter and the slim usb to micro USB adapters like these other than additional power:

(Because that’s what I have on hand)

Is there a reason that even when I put my sd into a zero w, I don’t get any response from a usb controller or keyboard?

I also have a usb wifi adapter laying around too, I did plug it in with the adapters I have but didn’t get anywhere with it. So it’s either underpowered or does it require drivers?

Those little things are also OTG adapters (i have some). If it doesn't work, then check the USB soldering on the pi. Check with a multimeter that there are no shorts. If you still have the USB ports on there you can at least take it apart and plug it in to them.

A USB keyboard should work though and not require much power!

I just cant figure out why my keyboard (and usb controller) arent working with it.
Ive tried the zero that is on the gem, three different zero w's and none of them are working with either device.
Ive used both of them before on numerous pi's and they both work with my mac.

I was thinking I could set everything up on a zero w then pop it into the gem.

also, do you know why the wpa_supplicant.conf doesnt activate wifi? Thats really my main goal here, if I can get it on my network I can transfer roms and ssh if I need to..

i don't know, make sure that the wifi icon is shown at the top corner with the menu toggle thing. The log files (/var/log/syslog and /var/log/messages) are useful to read through anything to do with wifi.

And it's a Zero without WiFi on board right? Well, first make sure a USB keyboard work to prove that your USB lines work

[SOLVED]

yes, but I have other zero w's to set it up with.

Anyways, apparently I was making the wpa supplicant incorrectly before. All is good now, although I didnt solve the USB problem, I dont really need it now.

Thanks for everything Kite.
