1- Thank you for the link. According this documentation there is no way to skip bootloader. I haven't time to write a bootloader, so I forget this solution. 2- I've studied uboot sequences, I can't optimize it directly : spent time is the time to load boot image (0.566233s) and kernel image (1.58259...
Hi, I use nanoPi M4 board and I work to improve the boot time. Initially the friendlycore image takes 28sec to start, now I can start image in 12sec (kernel and distribution optimization). I have one way to save time : uboot [0.668417 0.000026] U-Boot 2014.10-RK3399-06-ga6e7a35-dirty (Mar 31 2020 - ...
Ok I found the solution! Based on provided scripts from FriendlyARM (sd-fuse_rk3399), I made this script to flash parameters, kernel and dtb files only into the first raw partition. I copied usefull files next to my script : - kernel.img (kernel binary) - resource.img (dtb, logo, etc) - param4sd.txt...
I did lot of things on my current image Currently you are not receiving any updates. Not functional nor security for the most important part. That doesn't bothers you? For my current use case no, it's a POC, not connected to the web. If this kernel information was not missing, my POC would be finis...
Armbian support is much better and there are more people which can help you. https://docs.armbian.com/#what-is-armbian Ok, I did lot of things on my current image so I'll try to find a solution but it's good thing to know for the future, before to start an embedded development. thanks for your feed...

Hi, I'm user of this very good board which is NanoPi M4. I would like to add CAN-BUS support to the friendlyCore image by updating kernel, dtb and modules files of my current SDcard. Problem that I have : I don't understand how I can replace current files of my SDcard, without reflasing all the SDca...
Hi, To compile and install kernel/modules just follow these steps : 1- Environment export PATH=/opt/sysroots/friendlyARM/toolchain/4.9.3/bin:$PATH export GCC_COLORS=auto export PATH_SD_BOOT="/media/$USER/boot" export PATH_SD_ROOTFS="/media/$USER/rootfs" export MAKE="make CRO...
Hi, I found problem : into the s5p4418 modules folder on the SDcard, there are extra files that are not included with the kernel. I cleaned the module folder before to install my modules, It was my mistake. Finally, I copied original module folder from the reference image to my image and I replaced ...
Hi,

Hello! I have a simple question : someone knows which kernel config is used with the UbuntuCore QTE Image ? For information: 1- There is no /proc/config.gz entry with the kernel provided with UbuntuCore, option isn't enable so I can 't read by this way. 2- I followed the wiki page, I rebuilt the lic...
