make aarch64 EFI bootable iso problem
by 曹瑀宏 06 Mar '19

Hello: I'm trying to make a EFI bootable arm iso based on CentOS-7-aarch64-Minimal-1810.iso. I extracted Iso and get the flie tree like this: . ├── boot.catalog ├── CentOS_BuildTag ├── EFI ├── EULA ├── GPL ├── images ├── LiveOS ├── Packages ├── repodata ├── RPM-GPG-KEY-CentOS-7 ├── RPM-GPG-KEY-CentOS-7-aarch64 └── TRANS.TBL Then I add my own rpms into Packages and repack the iso with shell command: mkisofs -o /root/myiso.iso -eltorito-alt-boot -e images/efiboot.img -c boot.catalog -no-emul-boot -boot-load-size 4 -boot-info-table -V 'CUSTOM CENTOS' -R -J -T . After that I burned the myiso.iso to disc, but I couldn't get the "EFI device 0" choice option on Arm Server's BootManager while the CentOS-7-aarch64-Minimal-1810.iso was OK, I don't know what's the problem and how to make a cutomized iso which can be recognized as a EFI device on ARM Server? Thanks!

new build on a Cubieboard 2. I used https://armv7.dev.centos.org/repos/images/CentOS-Userland-7-armv7hl-generic… with xzcat CentOS-Userland-7-armv7hl-generic-Minimal-1810-sda.raw.xz | sudo dd of=/dev/sdb status=progress bs=4M onto a sata HD. The uSD card has uboot only. Booted fine. First step was to do a yum update and it failed: Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 Importing GPG key 0xF4A80EB5: Userid : "CentOS-7 Key (CentOS 7 Official Signing Key) <security(a)centos.org>" Fingerprint: 6341 ab27 53d7 8a78 a7c2 7bb1 24c6 a8a7 f4a8 0eb5 Package : centos-userland-release-7-6.1810.2.el7.centos.armv7hl (@instCentOS/$releasever) From : /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 Is this ok [y/N]: y Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-AltArch-Arm32 Importing GPG key 0x62505FE6: Userid : "CentOS AltArch SIG - Arm32 (https://wiki.centos.org/SpecialInterestGroup/AltArch/Arm32) <security(a)centos.org>" Fingerprint: 4d9e 39f1 499c a21d d289 77f8 cafe f11b 6250 5fe6 Package : centos-userland-release-7-6.1810.2.el7.centos.armv7hl (@instCentOS/$releasever) From : /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-AltArch-Arm32 Is this ok [y/N]: y Running transaction check ERROR with transaction check vs depsolve: xorg-x11-drv-vmmouse >= 14.0.0 is needed by (installed) kernel-4.14.82-201.el7.armv7hl You could try running: rpm -Va --nofiles --nodigest Your transaction was saved, rerun it with: yum load-transaction /tmp/yum_save_tx.2019-03-03.04-01.uUyhcp.yumtx [root@localhost ~]# what do I need to do to get this install updated? thanks
