Grigory Posted January 30, 2019 Posted January 30, 2019 Hello Folks, Seems like it is very strange behaviour with last Armbian at the OrangePi Prime board. It is continuiusly rebooting after power is on. Green led near the HDMI output is on, then after few seconds board is rebooting (led is off), and again. Board: OrangePi Prime SD Cards (the same results on both): SanDisk Extreme Pro microSDXC Class 10 UHS Class 3 V30 A1 64GB Kingston microSDHC Class 10 8GB Compilation environment: VMware Workstation 14.1.3 with Ubuntu Bionic installed Linux ubuntu-bionic 4.15.0-44-generic #47-Ubuntu SMP Mon Jan 14 11:26:59 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux Distributor ID: Ubuntu Description: Ubuntu 18.04.1 LTS Release: 18.04 Codename: bionic All steps are applied: https://docs.armbian.com/Developer-Guide_Build-Preparation/ For SD formatting tool is used: SD Card Formatter 5.0.1 For build image flashing tools are used (the same results on both): Win32 DiskImager 1.0 balenaEtcher 1.4.9 Tested builds of the Armbian where problem is observed: Official server release for OrangePi Prime (yesterday was "Armbian_5.69_Orangepiprime_Debian_stretch_next_4.19.13.img"): https://www.armbian.com/orange-pi-prime/ https://dl.armbian.com/orangepiprime/Debian_stretch_next.7z Manually compiled builds using compilation env described before (all builds are compiled with default build options): Armbian_5.73_Orangepiprime_Ubuntu_bionic_next_4.19.17.img Armbian_5.73_Orangepiprime_Ubuntu_xenial_next_4.19.17.img Armbian_5.74_Orangepiprime_Debian_stretch_next_4.19.17.img Armbian_5.74_Orangepiprime_Ubuntu_bionic_next_4.19.17.img Armbian_5.74_Orangepiprime_Ubuntu_xenial_next_4.19.17.img This build was able to start successfully: "Armbian_5.72_Orangepiprime_Ubuntu_bionic_next_4.19.13.img" But when I've started cpu load test it is freeze immedialetely. Script on python that was used for cpu load testing: # Produces load on all available CPU cores from multiprocessing import Pool from multiprocessing import cpu_count def f(x): while True: x*x if __name__ == '__main__': processes = cpu_count() print 'utilizing %d cores\n' % processes pool = Pool(processes) pool.map(f, range(processes)) Board is fully functional and working. Was tested with official "OranagePi Prime Ubuntu Desktop V2.1" build: http://www.orangepi.org/downloadresources/orangepiprime/orangepiprime_90a173615c3d08cc1efb22.html ubuntu_desktop_xfce_prime_V0_1.img With this build board is successfully start and running cpu loading script without any problems. Can you please lake a look into this problem? Thanks, Grigory.

Igor Posted January 30, 2019 Posted January 30, 2019 Mine crashed this way already at installing RPi monitor. http://ix.io/1zAF Spoiler
Igor Posted January 30, 2019 Posted January 30, 2019 With 4.20.2 it seems stable. 15 minutes of full load, small heatsink, temperatures settled around 80°
Igor Posted January 30, 2019 Posted January 30, 2019 Another test with 4.19.y ended in: kernel:[ 1403.832308] thermal thermal_zone0: critical temperature reached (90 C), shutting down which is quite normal. Strange.
Grigory Posted January 31, 2019 Author Posted January 31, 2019 Hello Folks, Seems like problem was due to bad power supply... But it is really strange because with official "OranagePi Prime Ubuntu Desktop V2.1" build anything is working fine... Maybe some slightly more gentle power settings? Anyway, right now with 2.5 Amps power supply all previous tested builds are working fine. Thanks a lot for your support! Thanks, Grigory.

Walter Hynson Posted March 14, 2020 Posted March 14, 2020 If you are using the plastic case ...remove the orange-pi board and carefully enlarge the hole where the power supply plug goes make it large enough for the plug to go all the way in,also insure power supply can output 2 amps solid.
