Hi,
My current setup:
1. Running swtpm on ubuntu to act as a virtual tpm.
2. Enabled measured boot, tpm, hash on u-boot
3. Openbmc image loaded on qemu.
With this setup, I am trying to get the tpm device through tcg2_platform_get_tpm2(struct udevice **dev) from u-boot(image-fit.c) . But I am getting error 19 (ENODEV). Any Idea why it is not recognizing the virtual TPM running on ubuntu?
Thanks,
Sandeep.
