Hi @Mani
I did just that and something odd happened…
At first, I installed the new firmware and the Debian images but I still had the exact same issues (with still the last 4 CPUs which failed to boot) but then I tried to re-install everything and when I ran hikey960-efi-prebuilt.sh for the second time, the Hikey960 booted on his own ! With the LED1 actually blinking at heartbeat as you said and not remaining ON as before… Even the bluetooth LED was ON…
(the switches were still on ON-ON-OFF)
And now, I can type in the UART console as if it had correctly booted but when I took a look in the logs, I saw that only the first CPU had booted…
(here’s the UART log : hikey960 boarid:5301 xloader use UART6scsysstat_value[0].clear reset source - Pastebin.com - we can see at line 653 that I can type in the console)
while the host console remains stuck at :
Sleeping till device resets… zzz
< waiting for any device >
I tried then to turn it off and reboot correctly (switches on ON-OFF-OFF) but still the same error as before : no access to the UART console, ‘only’ 4 CPUs down and LED1 remaining ON and not blinking…
I am lost here ; what am I doing wrong ?
Again, thanks for your help !
