=== Test Command ===

<span style="color:#FF0000;">'''JP5.1.0'''</span>

==== '''CAN''' ====
<pre>$ modprobe can
$ modprobe can-dev
$ modprobe mttcan
$ ip link set can0 type can bitrate 500000
$ ip link set can0 up
$ ip link set can1 type can bitrate 500000
$ ip link set can1 up
</pre>

In other terminal, run below command
<pre>$ candump can1
</pre>

then run
<pre>$ cansend can0 123#abcdabcd
</pre>

==== '''WatchDog''' ====
<pre>root@linux:/home/ubuntu$ sudo -s
root@linux:/home/ubuntu# sync; sleep 2; sync; echo c > /proc/sysrq-trigger
</pre>

==== '''TPM''' ====

Pre-install TPM-tools
<pre>$ sudo apt install --yes tpm2-tools
</pre>

(1)產生randon code
<pre>root@linux:/home/ubuntu# tpm2_getrandom --hex 20
</pre>

(2) 對指定檔案 msg.dat 加密
<pre>root@linux:/home/ubuntu# tpm2_createprimary -C p -c platform_primary.ctx
root@linux:/home/ubuntu# tpm2_create -C platform_primary.ctx -G rsa2048 -u key.pub -r key.priv
root@linux:/home/ubuntu# tpm2_load -C platform_primary.ctx -u key.pub -r key.priv -c key.ctx
root@linux:/home/ubuntu# echo "my test" >msg.dat
root@linux:/home/ubuntu# tpm2_rsaencrypt -c key.ctx -o msg.enc msg.dat
root@linux:/home/ubuntu# cat msg.enc
root@linux:/home/ubuntu# tpm2_rsadecrypt -c key.ctx -o msg.ptext msg.enc
root@linux:/home/ubuntu# cat msg.ptext 
root@linux:/home/ubuntu# cat msg.dat
</pre>

(3) 將資料儲存至 tpm 內存
<pre>root@linux:/home/ubuntu# tpm2_nvdefine -Q 0x1500031 -C o -s 32 -a "ownerread|policywrite|ownerwrite"
root@linux:/home/ubuntu# echo "write_tpm_adv" >  adv.data
root@linux:/home/ubuntu# tpm2_nvwrite -Q 0x1500031 -C o -i adv.data
root@linux:/home/ubuntu# tpm2_nvread -Q 0x1500031 -C o -s 32 -o read.data
root@linux:/home/ubuntu# cat read.data
</pre>

(4) 確認已經寫入儲存區域　
<pre>root@linux:/home/ubuntu# tpm2_nvreadpublic > nv.out
root@linux:/home/ubuntu# cat nv.out
</pre>

Error
<pre>ERROR: Esys_NV_DefineSpace(0x14C) - tpm:error(2.0): NV Index or persistent object already defined
ERROR: Failed to create NV index 0x1500031.
</pre>

fixed
<pre>root@linux:/home/ubuntu# tpm2_nvundefine 0x1500031
</pre>

==== '''RTC''' ====

DUT AC on:<br/> 1. Power on DUT and boot into OS.<br/> 2. Connect a LAN cable from the DUT to DHCP server.<br/> 3. Get a dynamic IP from DHCP server.<br/> 4. Type cmd to disable ntp service in DUT.
<pre># sudo timedatectl set-ntp false</pre>

5. Synchronize system time and RTC time with NTP server.
<pre># ntpdate tock.stdtime.gov.tw <===安裝ntpdate方式: $sudo apt-get install ntpdate <enter> 
# hwclock -w 
</pre>

6. Keep the DUT on for 24 hours.<br/> 7. Synchronize system time and RTC time with NTP server again and check inaccuracies.
<pre># ntpdate tock.stdtime.gov.tw && hwclock -s &&ntpdate -u tock.stdtime.gov.tw 
</pre>
