Error OE_PLATFORM_ERROR when running ego run helloworld on Ubuntu 22.04 with SGX support

[treeforest]

I followed the official tutorial to install EGo (version 1.8.0) on Ubuntu 22.04. However, when I run the helloworld sample, I encounter the following error:

root@U2204: ~/ego/samples/helloworld $ ego run helloworld
2025/12/19 03:33:28 INFO EGo version=1.8.0 git_commit=43c480809d3d183d54ebfd09c596e834a81f0095
[erthost] loading enclave ...
ERROR: enclave_create with ENCLAVE_TYPE_SGX1 type failed (err=0x1001) (oe_result_t=OE_PLATFORM_ERROR) [openenclave-src/host/sgx/sgxload.c:oe_sgx_create_enclave:454]
ERROR: oe_create_enclave failed. (Set OE_SIMULATION=1 for simulation mode.) [src/tools/erthost/erthost.cpp:main:265]

Environment:

• OS: Ubuntu 22.04
• EGo version: 1.8.0 (commit 43c4808)
• SGX support confirmed by cpuid:

root@U2204: ~$ cpuid -1 -l 0x7 | grep SGX
      SGX: Software Guard Extensions supported = true
      SGX_LC: SGX launch config supported      = true

Intel SGX SDK sample programs run successfully on this machine:

root@U2204:/opt/intel/sgxsdk/SampleCode/SampleEnclave$ sudo ./app 
Checksum(0x0x7ffcf54a0860, 100) = 0xfffd4143
Info: executing thread synchronization, please wait...  
Info: SampleEnclave successfully returned.
Enter a character before exit ...

What I have tried:

• Verified SGX driver is installed and /dev/isgx exists
• Confirmed BIOS SGX is enabled
• Tested Intel SGX SDK samples successfully

Request:
Could you please help me understand why ego run helloworld fails with OE_PLATFORM_ERROR despite the environment supporting SGX and Intel SDK samples working correctly? Any guidance on troubleshooting or configuration adjustments would be appreciated.

Thank you!
