I modified memory layout to give more RAM to OPTEE.
I compiled with my modifications and flashed and now , the board is not
serial logs stopped at :
INFO: TEE-CORE: Initialized
DEBUG: [0x0] TEE-CORE:init_primary_helper:628: Primary CPU switching
to normal world boot
I’m afraid I can’t really help too much here. There are simply too many
ways a broken memory map can lead to a hang during boot.
Also , recovery also not working. dmesg output is :
[ 8164.033094] option 1-5:1.0: GSM modem (1-port) converter detected
[ 8164.033225] usb 1-5: GSM modem (1-port) converter now attached to
[ 8164.705737] usb 1-5: USB disconnect, device number 24
[ 8164.705993] option1 ttyUSB0: GSM modem (1-port) converter now
disconnected from ttyUSB0
[ 8164.706008] option 1-5:1.0: device disconnected
Is there any other way to recover my board ? Pls help
The above message shows the bootloader is not loading so, on Hikey, this
is the only recovery mechanism that can help you.
Its rather odd that there is only a half second window between the USB
connect and disconnect. The disconnect is normal but the timeout should
be much longer than 0.5 seconds.
Are you running Linux in some kind of virtual machine? It is very
difficult to get a successful debrick like that (the board will change
VID/PID depending on which stage of recovery you are in; this messes up
USB device forwarding).
