my rock64 sometimes hangs with unknow reason. Enabling/testing watchdog did not help. Does hardware watchdog is working at all ? some outputs: # dmesg | grep -i watchd [ 0.838922] dw_wdt ff1a0000.watchdog: No valid TOPs array specified [ 0.928770] rk_gmac-dwmac ff540000.ethernet: Enable RX Mitigation via HW Watchdog Timer [ 3.920201] systemd[1]: Using hardware watchdog 'Synopsys DesignWare Watchdog', version 0, device /dev/watchdog0 [ 3.921218] systemd[1]: Watchdog running with a hardware timeout of 28s. # wdctl Device: /dev/watchdog0 Identity: Synopsys DesignWare Watchdog [version 0] Timeout: 28 seconds Timeleft: 18 seconds Pre-timeout: 0 seconds After doing kernel panic via echo c > /proc/sysrq-trigger device not rebooting. On raspberry pi that test is working fine.

Bedna I know that su command is a compiled binary but Orange Pi PC has a 32 bit ARM processor and not a 64 bit Intel (x86_64) processor. I find that extremely hard and impossible to believe that you missed the point.

Yes, applications are compiled into binaries, su is not a script. This is on for example Arch: $ file $(which su) /usr/bin/su: setuid ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=d47af40eeb87fea42d555df0d1385bc9a4b4df2c, for GNU/Linux 4.4.0, stripped Ok? So it's compiled with rust instead of C, still a binary. I find that extremely hard impossible to believe. https://www.reddit.com/r/learnprogramming/comments/lyw9gf/can_someone_explain_what_people_mean_by_binaries

i am running a H96(model RK3318) android tv box, its old, i have lost itss remote as well. basically noow i am tryinh to install ambrain os on it, but the conditon now is , even the android id now visible on the tv/monitor, basically when i insert the power cable on the display "boot" is showing with blue light. after few sec, some number like "07:01" is showing, but when i connect my htmi cable, the tv is detecting the htmi. but its showing no signal. basically there is no output on the display. i have tried many methods, there is no problem in htmi, or tv or cable. the andoird itself not booting. and the sd card method for ambrain also not working . tried the toothpick method and everything. but still its nott working!. i dont know why there is no output on the display. i dont know whhat issue. usb, htmi, everything is working. even charger also working.
