How to enable HW random generator?

Hi All,

Does anyone knows if Quark platform supports HW random generator?

In the latest Quark BSP v1.2.1.1, the /dev/hwrng device. does not exist.

I also try to enable some configs, but it doesn't work.

CONFIG_HW_RANDOM=y

CONFIG_HW_RANDOM_INTEL=y

CONFIG_HW_RANDOM_TPM=y

CONFIG_TCG_TPM=y

If it supports this feature, how to enable it? Thank you.

Best regards,

Daniel

Hi Charles,

We are still in progress to get the "/dev/hwrng".

 

 

We can enable the HW RANDOM and TCG TPM. But the "/dev/hwrng" still is not there.

To enable TPM, open file "yocto_build/conf/local.conf"

 

1.) Uncomment this line:

 

PACKAGECONFIG_append_pn-linux-yocto-quark = " quark-tpm".

2.) Then rebuild the image.

 

 

Please allow us some time to investigate this issue for "/dev/hwrng"

 

 

Thank you.

Best Regards

Anyway, have you try to enable TPM with the command I have provided before?
