Pi 4 blank screen with piCore 9.0.3 and 8.1.5

[Duncan T]

Hello everyone, this is my first attempt with piCore on a new Raspberry Pi 4. The Pi 4 works fine with Raspbian, but I have tried piCore 9.0.3 and then 8.1.5 on the same SD card and each time I get no video signal.

HDMI cable is plugged in the same port as when Raspbian works. I've tried two monitors, both work with Raspbian, neither with piCore.

From what I have read, I am expecting to see a prompt on screen when the Pi 4 starts up, but I get no video signal. Grateful for any help, am I missing something obvious?

I believe you need to use piCore 11.x with an RPi4

[Duncan T]

Thanks Juanito. I just checked the various downloads and notice that 9.x only has armv6 and armv7, while 11.x has armv7l too - I guess that's what you mean. My Pi 4 reports armv7l with uname -m.

It looks like nobody has built the zip files yet. Does anyone know where I can find build instructions?

Hi Duncan T
You can find a  Beta  release here:
http://tinycorelinux.net/11.x/armv7l/test_releases/RPi/

Hi Rich,
Thank you very much, I'll try that. Much appreciated.

[Duncan T]

Thanks again Rich - the beta boots as expected.

Thanks to you and Juanito for helping me get started.

Installed this beta release on Raspberry Pi 4 4G. tce-load for wget, make, gcc succeeded, so it works. But I did not succeed to install what I need: neither ntp nor samba (samba4) nor nfs-utils (error message no extension). tce-ab does not find them. Where can I find the content of repository for this beta?  All packages I need are present in repo for rel.9 that does not work on RPI4
 

[Juanito]

You can try extensions from the piCore 9.x armv7 repo to see if they work.

I am newbie in TinyCoreLinux (but not in Linux), and I have a question. Of course I can download needed tsz files from tinycorelinux.net/9.x/armv7/tcz/ by wget, but will i get all dependencies? In other words - does tsz package contain all dependencies? For example ubuntu deb package does not - it only instructs which packets it depends on, but ubuntu snap does.

[Juanito]

No, you will not get any dependencies.

If you download the *tcz.tree file for the extension you need, it will list all of the dependencies.

Note that you need the *tcz, *tcz.dep (where it exists) and *tcz.md5.txt files for each extension.
