@rippanda12 Only for your "info"... as you know WiFi works in the RebornOS of the RADXA Rock 5B (rockchip-rk3588)

Hi

I have a problem with my 4B because now I can't boot it.

Previously, I worked with Ubuntu preinstalled, ARMBIAN in the eMMC and RebornOS in TF card.

Now, I tried to use it with Android in TF and in the eMMC without success.. but the main problem is now I can't boot it as previously did. Armbian installed in the eMMC (or in the TF card) doesn't work.

Only a few lines in the monitor and the CoolPi logo... again and again

Apparently, I have a problem with the "loader" ?

Thank you in advance by your help

Thank you @jack_admin

Do you mean that on Android the wifi does not work yet?

@rippanda12 Thank you for the info.

RebornOS is the "only" linux where Kodi last version can be installed

We hope you solve the WiFi "problem" as soon as possible. THANKS!

@george Armbian, for example

I'd like to test Android or OpenEuler, for example ... but I don't know how to install "preinstalled" images .

It seems is not enough to use BalenaEtcher to create a SD/TF to start/run. Help?

Of course @george

Here are some of the pictures of my next review of this device in my website www.pcdemano.com

Has anyone managed to use WiFi on Cool Pi 4B with RebornOS?

Thank you @jack_admin but the problem remains

I format the eMMC and flashed the RebornOS with Balena. Then I installed online through the LAN (wired connection), reboot the device.

The problem remains and I can't connect to my LAN using Wireless. It doesn't accept my credentials that are using in my another devices, of course

I tried creating an access point in my iPhone with the same problem

Hi again

Now, I have my CoolPi working fine with RebornOS but... without wireless connection.

Wired connections works for Internet but when I tried to enable my wireless connection always ask for my password. CoolPi see without any problems all available wireless networks but it does not accept the password

@jack_admin Thanks!

I wipe/format the eMMC and installed again the RebornOS image and now WORKS!

I thought that Balena format previously the device ... but don't

@george Thanks

I've tried with a SD card ... and the problem remains

@Pharizna said in cool pi 4b RebornOS support:

Thank you ... but my cool pi doesn't start with this image

I've tried flashing my 128 GB eMMC and a SD card without success

Previously I've used with ARMBIAN img without any problem.

Thank you in advance

The problem is bigger now since my device doesn't boot up with RebornOS, Armbian or Ubuntu. It's stuck in an endless loop with the CoolPi logo.

What can I do? It's as if the "boot files lost? I'm just copying the ARMBIAN, UBUNTU image with BalenaEtcher to the eMMC, isn't that enough?

Thank you ... but my cool pi doesn't start with this image
