SGX suddenly was unavailable, the day before was still good. My SGX is installed under ubuntu18.04.
" Info: Please make sure SGX module is enabled in the BIOS, and install SGX driver afterwards.
Error: Invalid SGX device. "
Have tried the following solutions: 1.Upgraded BIOS, no use 2.Reinstalled the SGX driver under Windows, no use 3.Reinstalled the latest version of SGX, no use .
Please help me, what should I do? Thank you very much.
Error message suggests that your SGX device (/dev/isgx) is missing/damaged.
Reinstalling SGX driver should help, but make sure to first actually uninstall it, as per instructions here: https://github.com/intel/linux-sgx-driver#uninstall-the-intelr-sgx-driver .
Still, if you wiped OS then possibly you have recreated /dev/isgx and it still didn't help. In such case, what is your output after running this: https://github.com/ayeks/SGX-hardware ?
