OK, lets check if you have libEGL, libGL and libGLES loaded:
Code: [Select]
$ ls /usr/local/lib/lib*GL*.so
..and if you have the graphics acceleration drivers loaded:
Code: [Select]
lsmod | grep vc4

/usr/local/lib/libEGL.so        /usr/local/lib/libGLESv1_CM.so
/usr/local/lib/libGL.so         /usr/local/lib/libGLESv2.so

Hmm - I'm wondering if an RPi3+ behaves like an RPi3 or an RPi4 in terms of graphics acceleration.

You should see the screen blank momentarily when you load the graphics-KERNEL extension - when you enter this:
Code: [Select]
$ tce-load -i graphics-KERNEL
..is graphics-4.19.81-piCore-v7 loaded or do you see an error message saying graphics-4.19.81-piCore-v7l cannot be found?

Other than that, perhaps you have a corrupted or missing dep file or md5.txt file (which prevents scanning for updates).

At least we have confirmed that an RPi3+ acts like an RPi3 as far as loading kernel modules is concerned.

If you are sure you have copied "dtoverlay=vc4-kms-v3d" correctly into config.txt under the "[PI3]" header, then loading graphics-4.19.81-piCore-v7 after reboot should momentarily blank the screen as the vc4 kernel driver is loaded.

Could "graphics-4.19.81-piCore-v7" auto load after reboot?

Only if you have it set “onboot” - for testing purposes it would be better not to do this.

Have you made one of the following entries in /mnt/mmcblk0p1/config.txt:
Code: [Select]
[PI3]
dtoverlay=vc4-kms-v3d

[PI4]                   
dtoverlay=vc4-fkms-v3d

Note that you need to reboot after making the changes.
It is nothing in my /mnt/mmcblk0p1 because partition disk to /mnt/mmcblk0p2/.
Should I create file of config.txt in /mnt/mmcblk0p2/ ?

If the results of this:
Code: [Select]
$ fdisk -l
..show /dev/mmcblk0p1, then:
Code: [Select]
$ sudo mount /dev/mmcblk0p1
$ vi /mnt/mmcblk0p1/config.txt

.and add:
Code: [Select]
[PI3]
dtoverlay=vc4-kms-v3d

Should I clear them or add

There is no blank page on epiphany. Thank you so much.
I met another problem there is garbled text on the web page.
Does it exist like "fonts-arphic-uming" or another font to install on piCore?

OK, I try to find.
By the way,
I find it will spend much time loading web on epiphany.
And it use 70% RAM on system.
Is it normal?

Most of the browsers are memory hogs - for me the best browser for tinycore/picore is fifth, but it needs modifying for use in 11.x with openssl-1.1.1
