Re: [tpmdd-devel] tpm_tis being loaded when tpm_infineon should be

[Michael D. <mi...@do...>]

  Thanks for your help Rajiv,

I tried the sequence of commands as you posted and had similar problems 
as the other day:

mdoube@doris:~$ sudo rmmod tpm_tis
[sudo] password for mdoube:
mdoube@doris:~$ sudo modprobe tpm_infineon
mdoube@doris:~$ cat /proc/interrupts | grep tpm
mdoube@doris:~$ tcsd -f&
[1] 23866
mdoube@doris:~$ TCSD ERROR: fopen(/etc/tcsd.conf): Permission denied
^C
[1]+  Exit 4                  tcsd -f
mdoube@doris:~$ sudo tcsd -f&
[1] 24391
mdoube@doris:~$ TCSD TDDL ERROR: Could not find a device to open!

in another tty:
mdoube@doris:~$ sudo tpm_version
Tspi_Context_Connect failed: 0x00003011 - layer=tsp, code=0011 (17), 
Communication failure
