rocksa Posted May 22, 2019 Share Posted May 22, 2019 Hello. I wanted preempt-rt kernel for my armbian rockpro64 so i have compiled and generated preempt-rt 4.4.167 deb kernel package. I have installed my custom kernel deb package but after reboot the system boot in old kernel not the custom kernel. How i can set the system to boot from custom installed kernel ?(4.4.167-rt176 is my custom kernel) $ ls -a /boot . boot.cmd dtb-4.4.174-rockchip64 System.map-4.4.174-rockchip64 .. boot-desktop.png Image uInitrd armbianEnv.txt boot.scr initrd.img-4.4.167-rt176 uInitrd-4.4.167-rt176 armbianEnv.txt.out config-4.4.167-rt176 initrd.img-4.4.174-rockchip64 uInitrd-4.4.174-rockchip64 armbian_first_run.txt.template config-4.4.174-rockchip64 .next vmlinuz-4.4.167-rt176 boot.bmp dtb System.map-4.4.167-rt176 vmlinuz-4.4.174-rockchip64 Link to comment Share on other sites More sharing options...

Check the /boot/Image, /boot/uInitrd and /boot/dtb, they are symbolic links that need to be redone pointing to newer bins/folder . Link to comment Share on other sites More sharing options...
rocksa Posted May 22, 2019 Author Share Posted May 22, 2019 What is dtb ? My custom kernel has no dtb. Link to comment Share on other sites More sharing options...

DTB = Device Tree Binaries Normally, when you did your build, you should have a dtb package generated. Since 4.4.167 and 4.4.174 are not to far from each other, the DTBs are maybe compatible, in such case try out your new kernel with the old DTB.

rocksa Posted May 22, 2019 Author Share Posted May 22, 2019 No it does generated when i install custom kernel deb at /boot. If fail to boot my custom kernel with 4.4.174 dtb can i recover boot to 4.4.174 armbian kernel? Link to comment Share on other sites More sharing options...

No, it is a separate DEB, for example, something like : output/debs/linux-dtb-dev-rockpro64_5.81_arm64.deb 34 minutes ago, rocksa said: can i recover boot to 4.4.174 armbian kernel? Yes, by replacing the symbolic links like it was before ... Link to comment Share on other sites More sharing options...
rocksa Posted May 22, 2019 Author Share Posted May 22, 2019 no does not generated separate deb for dtb generated only kernel/headers/libc debs. I made symlinks and now system does not boot. How can i recover easily ? Link to comment Share on other sites More sharing options...
martinayotte Posted May 22, 2019 Share Posted May 22, 2019 1 hour ago, rocksa said: no does not generated separate deb for dtb generated only kernel/headers/libc debs. Are you using Armbian build scripts or plain make ? Armbian build scripts are producing something like : output/debs/linux-dtb-dev-rockpro64_5.81_arm64.deb 1 hour ago, rocksa said: I made symlinks and now system does not boot. Replacing symlinks properly should work since it was booting before ... Check them again, make sure they are pointing to previous files. Link to comment Share on other sites More sharing options...
rocksa Posted May 22, 2019 Author Share Posted May 22, 2019 no iam not used armbian scripts i have done make menuconfig make deb-pkg i used kernel from this repo https://github.com/rockchip-linux/kernel/tree/develop-4.4-rt176 Link to comment Share on other sites More sharing options...
martinayotte Posted May 22, 2019 Share Posted May 22, 2019 1 hour ago, rocksa said: no iam not used armbian scripts i have done make menuconfig make deb-pkg Then, using make, you can build DTBs with "make INSTALL_DTBS_PATH=$PWD/output/dtb dtbs" ... They will be copied into $PWD/output/dtb ... BTW, are you compiling that locally on the RockPro64, or thru cross-compiling ? Link to comment Share on other sites More sharing options...
rocksa Posted May 22, 2019 Author Share Posted May 22, 2019 locally on rockpro64 i have done this but no dtb generated.. $ make INSTALL_DTBS_PATH=$PWD/../output/dtb dtbs CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h CHK include/generated/bounds.h CHK include/generated/timeconst.h CHK include/generated/asm-offsets.h CALL scripts/checksyscalls.sh make[1]: 'include/generated/vdso-offsets.h' is up to date.
