Tools

Test Command

JP6.2

CAN

Hardware setting

Set JPCAN1 Jumper to Can mode

Switch SW3 to ON

<Receive> In terminal, run below command

$ sudo su
# modprobe can
# modprobe can-dev
# modprobe mttcan
# ip link set can0 type can bitrate 500000
# ip link set can0 up
# candump can0

<Transmit> In other device terminal, run below command

$ sudo su
# modprobe can
# modprobe can-dev
# modprobe mttcan
# ip link set can0 type can bitrate 500000
# ip link set can0 up
# cansend can0 123#abcdabcd

WatchDog

$ sudo su
# sync; sleep 2; sync; echo c > /proc/sysrq-trigger

Audio

Line-Out

$ aplay -D hw:1,0 <WAV file>

TPM

Pre-install TPM-tools

$ sudo apt install --yes tpm2-tools

(1)產生randon code

$ sudo su

root@linux:/home/ubuntu# tpm2_getrandom --hex 20

(2) 對指定檔案 msg.dat 加密

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

(3) 將資料儲存至 tpm 內存

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

(4) 確認已經寫入儲存區域　

root@linux:/home/ubuntu# tpm2_nvreadpublic > nv.out
root@linux:/home/ubuntu# cat nv.out

Error

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

fixed

root@linux:/home/ubuntu# tpm2_nvundefine 0x1500031
