Suggest updating uboot to the latest version and then trying USB BOOT. The latest development branch has been optimized for some USB drives. Of course, you can also write images to EMMC through UMS.

@george It seems I have to compile boot loader first?

https://cool-pi.com/topic/380/cool-pi-4b-cm5-linux-system-support-compile-u-boot

Following this guide.

Ubuntu 24.04 don't have python2, can't compile directly, annoying

@plumlis

sudo ln -s /usr/bin/python3.12 /usr/bin/python

@george

Already did. Seems it doesn't work.

The following is what I have compiled and can be used directly.
RKDevTool_v3.13_for_window.rar

plumlis

@george thanks.
The only way to upgrade uboot is following this guide?

https://forum.cool-pi.com/topic/162/how-to-upgrade-the-boot-loader-of-coolpi-4b

short two pins and conect to PC to upgrade loader?

Follow the steps below to operate:
1.USB cable for TYPEC interface and X86 computer connection
2. Run sudo reboot loader on the shell，The machine will enter loader mode, as shown in the following figure

3. Click on the tool to force entry into maskrom mode

4. Check the option to force writing by address

5. Burning, the machine will automatically restart after completion

plumlis

@george Nice, I'll try it.

Btw I finally figured out why my USB Disk can't boot up.

The the fedora image you gave me have Boot up info in cmdline like this:

rootfs=LABLE=writable

And my EMMC also has a parttion labled writable(dafault).

So actually it booted up from usb disk, but set writable lable on emmc as root, So I boot back to my ubuntu. That mislanding me ths USB disk can't be boot up.

I changed to rootfs=UUID=(my usb disk UUID). And I can boot into fedora image now.

george

@plumlis
You can change the EMMC label to writable1 or another name.

plumlis

Upgrade finished, Seems boot up speed much faster than before.

Will play around with fedora image.

BTW I compiled kernel 6.1 from github https://github.com/yanyitech/coolpi-kernel kernel 6.1 branch and It can't boot up.

Hope new kernel will come soon.

Many thanks for your help.

plumlis

Just uncheck "Use recommended performance settings" and "Use hardware acceleration when available" in Firefox settings will fix this issue.

But also will have no GPU acceleration.

@plumlis
FFmpeg can be changed to a native package. Or using the Chromium browser, the decoding issue of this player has been bothering us for a long time. Take some time later to focus on solving it.
