you need to know how u-boot boots linux kernel and brings it userspace. the only thing you need to care is boot command, but the boot command you should make u-boot to know where to find kernel/initramfs/dtb, no mater where you put them. for no initramfs,. if your kernel has enough driver to mount your root device, I guess that's fine. but usually initramfs is required.

Rockchip Socs are best ARM socs for Linux desktop use. hope board makers build good devices for us.

this improvement only in some certain cases. and the cases are mixed in our daily use, maybe not high frequently used, so 8x~20x * frequency, that's actual improvement, we can feel.

thanks to Armbian leads me to the Arm world, I can build my own os image for my arm SBC.

Paypal is not usable popular in China, would you like to add Alipay or wechat Pay, if you want to accept RMB donation. BTW, I think some of you have experience in buy products in Aliexpress, thus you may have an Alipay accounts. Alipay: https://intl.alipay.com/?locale=en_US Wechat Pay: https://pay.weixin.qq.com/index.php/public/wechatpay

the simple way: install pulseaudio mpv -ao pulse xxx.mp3

I guess no NPU support, it looks like Rockchip doesn't release NPU driver to public, I have checked their github many times.

I think may be we can remove spi flash from motherboard, thus switch to emmc boot or SDcard boot.

it looks you are using mainline kernel, thus vdpau video acceleration is not available. you need to read: https://forum.armbian.com/topic/13622-mainline-vpu/

so i'm lucky, just buy a cheaper one, not Samsung chromebook plus. used flip only 230RMB, samsung plus will be 1000RMB

my flip just arrived, 4+32. it's used, but in good condition. I have sent email to maintainer ask help for build flash u-boot. but need approve to send email to u-boot mailing list.

thanks @hexdump, I read your project, and I have found some other, it looks like all the effort is to install in 3rd OS to external storage. why?

recent days I find Chromebook may be better Arm devices with laptop form factor. compare with Pinebook pro, Chromebooks are cheaper, and mass product, and better tested. why no much people discuss how to install 3rd OS to its internal emmc, or reflash its uboot? I have searched on ArchArm forum, only 1 topic. but there actually a way to reflash uboot, and mainline uboot already has support for arm based chromebooks. It should be easy, but why no discussion?

about amlogic audio in kernel 5.7, there is an issue: http://lists.infradead.org/pipermail/linux-amlogic/2020-July/007558.html revert related patch or wait 5.8
