      Let me briefly introduce the current situation of the NAND flash industry. The best A-class die is used as a high-capacity and high-value storage device for first tier brands such as SSDs and EMMCs. The worse one is used for second tier brands such as EMMCs and NAND FLASH, and the worse one is used for a large number of bad fast devices. The 8GB capacity can be reduced to 4G or 2G for USB drives or T cards. There is even worse junk die, which will appear on the T card that costs a few yuan on Mouduoduo. So if doing system mirroring, it is recommended to use SSD or SATA portable hard drives, as both performance and reliability are the best.

        @george I knew that.
        But the point is I can't find a usb stick to make this fedora image boot up.
        Wiki said only usb 2.0 disk can be boot up.

        I tested all my usb 3.0/2.0 devices. Only one usb 2.0 stick can be booted. But it's 16GB, fedora image is 17GB and can't write to it.

        I just asked you to recommand a usb device can be boot up.

          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

                  The following is what I have compiled and can be used directly.

                    @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?

                          @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.

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

                              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.

                                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.

                                  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.
