I have an Atmel 97SC3201 in my computer and set the following in the kernel:CONFIG_HW_RANDOM_TPMCONFIG_TCG_TPMCONFIG_TCG_ATMEL/dev has tpm0 and hwrng, but running this command returns the following:head -c 2 /dev/hwrngoutput:head: error reading /dev/hwrng: Input/output errorIn dmesg these messages appear:tpm_atmel tpm_atmel: A TPM error (2048) occurred attempting get randomadditional tries yield these messages:tpm_atmel tpm_atmel: A TPM error (6) occurred attempting get randomAny ideas why this fails or better, how to get it working?
Why doesn't `head -c 2 /dev/hwrng` work?
