First I tried to reproduce the crash on one of our porterboxes[4] `amdahl` (where I could not reproduce the bug, git-annex runs just fine), but I only much later figured out that it run armv8l: [4] https://db.debian.org/machines.cgi?host=amdahl dpat@amdahl ~ % export sessionid=913555 dpat@amdahl ~ % schroot -b -c sid_armel-dchroot -n $sessionid I: 00check: Untarring chroot environment. This might take a minute or two. I: 99porterbox-extra-sources: o To install build dependencies run I: 99porterbox-extra-sources: dd-schroot-cmd -c 915333 apt-get update I: 99porterbox-extra-sources: followed by build-dep/install as appropriate in the host system. I: 99porterbox-extra-sources: o If you started this session with schroot -b, please do not forget to run I: 99porterbox-extra-sources: schroot --end-session -c 915333 I: 99porterbox-extra-sources: when you no longer need this environment. 915333 schroot -b -c sid_armel-dchroot -n $sessionid 9.08s user 5.17s system 126% cpu 11.293 total (sid_armel-dchroot)dpat@amdahl ~ % uname -a Linux amdahl 4.9.0-8-arm64 #1 SMP Debian 4.9.144-3.1 (2019-02-19) armv8l GNU/Linux I also tried on `abel` but its a armv7l. I then wanted to setup a qemu-arm environment but I am stuck finding out which machine/cpu option would be correct. I found [1] and [2] which states that the CPU "Feroceon 88FR131 rev 1 (v5l)" is a actually a Marvell Kirkwood 88F6281. (Ok, [3] says that qnap ts-11x runs on Kirkwood system-on-chip (SoC) from Marvell). [1] https://www.chainsawonatireswing.com/2012/01/07/find-out-which-cpu-your-synology-diskstation-uses/ [2] https://www.7-cpu.com/cpu/Kirkwood.html [3] https://www.debian.org/releases/stable/armel/ch02s01.html.en (see 2.1.4) So, is it possible to emulate a armv5 and if yes, how? Thanks. Regards from the Debian BSP201904, Salzburg, - Darsha
