GPIO stuff has no script... for sim swap/wifi enable (script included also includes coldboot)

[ghost]

The problem you're addressing (if any)

GPIO stuff has no script... for sim swap/wifi enable/coldboot

Describe the solution you'd like

Include below script in GPIO section which encapsulate the gpio commands possible

Where is the value to a user, and who might that user be?

So they don't have to script it again...

Describe alternatives you've considered

Making a github repo... but currently I have no puff to maintain it... maybe when I have the auto firmware downloader/updater finished... but that could be months or never.

Additional context

There is a lot of information scattered around which could be very useful. Wish you poured it in one location... and link it from you frontpage.

For the apu tools aficionados...

[macpijan]

Hello @Tristan79 @Monkeycat-nl and thanks for these ideas. I can see there is a need for such script among the PC Engines user base, so we might adapt it to the PC Engines github and documentation.

Would you like to elaborate on how you tested this script and which cards did you use?

Thank you for your contribution!

[ghost]

apu4c4, 2x apu4d4... 3x vlx600 wifi cards...

you should probably update in your docs which wifi card works... the recommended wifi card (200/600/900) is NOT available due to the chip shortage... (and if you can find one berry expensive)

the metal box...sd slot cutout and atleast two more wifi antenna mounting circles would be nice...

do these work? https://nl.aliexpress.com/item/1005003173274741.html (with beter search 10 buck cheaper...)

also if i have known the apu3 and apu4 could not use two wifi cards internal... i probably have bought the apu2 4gb version... or does it work? can I use the a second wifi card in the middle slot?

or can I only use a mini-pci usb extender...???

would be nice... so you can use 2.4g and 5g or in the future 5g and 6g... without an external usbstick (do not use wifi usb3 stick especially when using 2.5gb ethernet usb3 sticks... why? think about usb 3 and usb 2 bandwidth....)

also https://www.bol.com/nl/nl/p/samsung-evo-plus-microsdxc-256-gb-versie-2020/9300000001986684/?s2a= does not work in sd 3.0 mode... in debian bullseye (and ipfire). Total kernel crash in dmesg... Small files will copy... large files will crash the kernel... it will copy a couple of gigs... en then crash... disabling sd 3.0 will fix it... speed reduction for backups made to the sd card is significant.... i have 3 apu4 and 3 samsung sd cards... all have the same behaviour...so that is no hardware fluke..

4gb mem is ok for firewall... but barely enough to run a vm homeserver webserver email database on top of a hypervisor... not to mention docker... please consider a model for home (lab) users... upgrading to more memory... ;-)

For the recommended wifi cards... I have an ath driver for debian automatic patching scripts... yes... it recompile the ath drivers when a new kernel is updated... why? the last remaining card (wlx600 in my instance) and linux NEW behaviour if the country is not set... which 2 of 3 of my card i bought was the case... this will limit the card to almost NO channel... it excludes almost every channel...

patching it will remove that limitation... will upload on request :-)

Added https://nl.aliexpress.com/item/1005003444392756.html for 2.5gb network... throughput seems to be right...

You can use the scripts...

[ghost]

also no throtling with 100% cpu on 4 cores due to temperature.... never ever got above 80c... recommended swap size at least 10gb... (zram can help :-) 4gb is just... minimal :-)

scripts tested on ipfire & debian.. :-)

[ghost]

@Tristan79 show the scripts...

[ghost]

@Tristan79 thanks...

debian... wifi

https://github.com/Monkeycat-nl/APUWifi/ in combo with https://github.com/singe/wifi-frequency-hacker

[ghost]

@macpijan send new hardware to test.... you can use scripts :-)

[ghost]

@Monkeycat-nl all good...

no worries! here is my hostapd for 4 wifi network... in combo with the driver recompile it should provide 4 networks... the extra wifi networks will disappear when the driver is not recompiled :(

make sure things like bridge=bryellow (in my case vlan 600 defines as bridge yellow) are set... could not go beyond 4 wifi networks... adding an extra will not work...

@macpijan at least be in front of the queue of new hardware... :-)

@Tristan79 sadly sd 3.0 bios option is broken... every linux kernel 5 will crash...

anyway wifi script work great! big test will be next debian kernel upgrade have unattended-upgrades enbled... :-)

adding a fifth wifi network did not work... as you predicted. did you try the mesh option?

[ghost]

No... no mesh (there are no docs or examples to follow for mesh)... it was already a bitsh getting hostap to work to have more then one bssid... to get it to work required bssid to be harcoded into the config file for every extra bssid... would not work without it... (and its kind pikky about the bssid mac address... shoudl not be but it is...)

already had two debian kernel upgrade... script runs fine :-) if you don't mind the 8 minutes downtime when it compiles the patch driver... after a new fresh kernel reboot :)

@Monkeycat-nl a six'sed not a fifth :-)

[ghost]

my bad :-) four extra wifi networks... on top of the existing one... fifth extra not working... (so only 5 bssid/wifi networks total working)

[ghost]

jup... same for realtek usb wifi stick I use... which host all the 2.4g stuff... (vlx600 does the 5g stuff) seems 5 (or 4 extra) is the limit... for hostapd... do not know why, should not matter, as does the bssid macaddress... should not matter when not hardcoded but it does...)

[ghost]

@macpijan running debian latest... on apu4... can we add an extra wifi card in the middle slot?

if not a lot of people are going to assume the one wireless card will handle both 2.4g and 5g which... almost no card will do... it's either, not both... so you need at least TWO wifi cards...

and a lot of people will go for the extra lan port and the higher number (apu4 vs apu2)... not knowing that one lan port less on the apu2 model... will work with two wifi cards... and still have 4gb of memory... apu2 supports two wifi...

apu4??? if not... that means an external usb wifi card... seems to be a waste of a pcimini slot... and a waste of usb bandwidth...

what's up with that?

[ghost]

@macpijan @Monkeycat-nl ...not to mention the missing header for the second internal usb2 header... good luck soldering that when already placed the motherbord in the case.. why is that missing???

did I mention the coil whine? apu4c4 not... apu4d4 2x anoying whine... @Monkeycat-nl u got coil whine?

[ghost]

@Tristan79 idk... the unit is in the boiler room.

@macpijan I fixed the init... will now only initialize when the gpio exports does not exists... should remove all error messages... when running twice. enjoy the code.
