hikey_debian: tee-supplicant fails: please clarify the build instruction around tee-supplicant, xtest

[Valeri99]

Hello,

I am eager to run xtest after the long fighting with ethernet connection.
Please clarify the instruction for the hikey_debian at the
https://github.com/OP-TEE/build

The instruction suggests to do: $ make all run
But there is no target "run" in the hikey_debian.mk (?)
(I am asking because according the instruction the "make run" is needed
for "xtest" later in the instruction).

The instruction suggests to run:
tee-supplicant &
xtest
Do I need to do the "make send" before to run "tee-supplicant" and "xtest" ?

Anyway:

1) Test #1

(I used tag 2.3.0 everywhere)

I just tried to run "tee-supplicant &" strictly according to instruction
(i.e. after "make flash" and booting the device up)
That is what I have:
tee-supplicant &
[1] 1079
linaro@linaro-alip:~$ ERR [1079] TEES:main:392: error opening [/dev/opteearmtz00]

2) Test #2

On the host machine:
I run the "make send" before to run "tee-supplicant" and "xtest" on the HiKey.
On the HiKey machine:

I tried to reboot the HiKey machine after test#2
but the booting up crashed.

Please, help.

Thanks a lot.

@Valeri99 Did you manage to resolve the issue yourself?

[Valeri99]

@vchong
It works for me for tag 2.2.0
In my post just I wanted to know in particular if the confusing output like
------- blockdev: ioctl error on BLKROSET: Operation not permitted -------
is normal and also I needed an obvious confirmation that "make send"
is needed.
Yes, indeed, the confusing output seems to be normal (it does not affect the later test execution).
Yes, indeed, the "make send" is obviously needed.
Thanks.
