Could you make sure that there isn't another instance of tpm2-abrmd running
in the background already?

# systemctl status tpm2-abrmd

Hi Tadeusz,
I reinstalled  tpm-tss , tpm-abrmd, tpm-tools.
Now they can use with /dev/tpm0.

Thank you!
Sherry

[tpm2] It is a problem about device or resource busy when I use the tpm2-tools

Hi all,
The packages that I have installed(ubuntu16.04.2 with kernel-4.16.2) :
# install TSS itself
git clone https://github.com/tpm2-software/tpm2-tss.git
cd tpm2-tss
./bootstrap
./configure --enable-unit
make check
sudo make install

# Install abrmd itself
git clone https://github.com/tpm2-software/tpm2-abrmd.git
cd tpm2-abrmd
./bootstrap
./configure --enable-unit --with-dbuspolicydir=/etc/dbus-1/system.d
dbus-launch make check
sudo make install

# Install tools itself
git clone https://github.com/tpm2-software/tpm2-tools.git
cd tpm2-tools
./bootstrap
./configure --enable-unit
make check
sudo make install
And I can see /dev/tpm0 and /dev/tpmrm0 with the the tpm_tis.ko in the kernel-4.16.2.
But I have a problem as follows:
(1)#strace tpm2-abrmd --tcti="device:/dev/tpm0"  --allow-root
[cid:image001.png(a)01D471D2.AD346530]
(2)In a C  program:
     fd = open("/dev/tpm0",O_RDWR);
result:
open("/dev/tpm0", O_RDWR)               = -1 EBUSY (Device or resource busy)
So could someone give advice  to me how to solve this problem?
