Frequently Asked Questions¶
- I used my personal email address while requesting for access, and it has been more than two working days. I have not yet received the product key. What should I do?
It is recommended to use an official email address instead of your personal email address.
- I used my official email address while requesting for access. It has been more than two working days, and I have not yet received the product key. What should I do?
Downloading of Intel® Edge Controls for Industrial involves a manual approval process. Make sure your company has a CNDA before submitting the request for access. If you have any questions regarding the CNDA with Intel®, contact the Intel® Sales Representatives.
- I received the email with the product key. What should I do next?
After receiving the product key, you can download the ECI Release Package.
- My colleague had requested for access and received the email with the product key. However, I am unable to download. Do I need to request for access again?
Yes. The access is granted for the email address and not the company. So, if you want to download using a different email address, you need to request for access for that email address.
- What is the minimum free space required to build Intel® ECI?
A minimum of 150 GB free space is required to build Intel® ECI. For more details, refer to system requirements.
- Building of Yocto is time consuming. How can I speed up the compilation?
To speed up the compilation, create a local cache.
Known Limitations¶
This section lists the known limitations with ECI. Fixes to these limitations are expected in the future releases of ECI. Refer to your ECI distribution channel to learn more about updates on ECI.
For other issues, go to https://premiersupport.intel.com/ (Login with your Intel® account) and create a new Intel Edge Software Recipes Case under the Software/Driver/OS category and the Industrial Edge Control Software sub-category.
Limitation #1 - ECI Build errors¶
When building ECI, the build process may fail due to do_fetch errors. These errors occur when the build engine is unable to reach external dependencies via the network. Most often, these errors occur due to network instability, broken mirrors, or proxy server instability.
Mitigation Actions
It is recommended to avoid environments with network proxies and heavy network congestion.
Often, repeating the build process will eventually result in a complete build.
Outages and offline mirrors tend to be intermittent. Attempt the build again after waiting a few hours for the issues to subside.
Limitation #2 - ACRN Service VM monitor output¶
On some hardware platforms, the ACRN Service VM may not output anything to the attached monitor. Only the GRUB warning “WARNING: no console will be available to OS” will be visible upon booting.
Limitation #3 - ACRN VM filesystem read-only¶
When intensive storage I/O is sustained within a virtual machine (VM) running on the ACRN hypervisor, some I/O requests may be dropped. Linux* kernels will interpret this behavior as faulty storage hardware and automatically remount the affected storage partition as read-only. This situation may occur if storage benchmarks are performed within the VM.
Mitigation Actions
Avoid sustained intensive storage I/O within the VM.
Assign more virtual CPUs to the VM to increase the effective I/O bandwidth.
Limit the number of VMs running simultaneously.
Avoid sharing physical CPUs between VMs.
Limitation #4 - No results from msi-jitter benchmark¶
Benchmark msi-jitter /opt/benchmarking/msi-jitter does not provide results on certain devices. Known, affected devices are Karbon 700 and Karbon 300.
************ RESULTS (ns) ************ [79774.994363] * Max: 0 [79774.994363] * Avg: 0 [79774.994364] * Min: 0 [79774.994364] *********** *********** ***********
This behavior is currently observed only for i210 Ethernet NICs connected to cascading PCI bridges. The following is an lspci -t example from a Karbon 700 device:

In the above example, Ethernet controller 04:00.0, 05:00.0, 06:00.0, 07:00.0 would be affected as they connect
to 00:1c.6 PCI bridge: Intel Corporation Cannon Lake PCH PCI Express Root Port #7 (rev f0)
and PCI bridge: Pericom Semiconductor PI7C9X2G608GP PCIe2 6-Port/8-Lane Packet Switch.
Mitigation Actions
Run msi-jitter benchmark on non-cascading PCI bridged Ethernet controllers. E.g.
./run_msijitter.sh "0000:0a:00.0" 1 10 10, for Karbon 700. This behavior is unique to the msi-jitter benchmark and does not affect regular operation of the Ethernet controller. The msi-jitter benchmark kernel driver has to be fixed with upcoming releases.
Limitation #5 - Cannot start CODESYS Linux runtime¶
The CODESYS Linux Runtime may not start correctly on +12th Generation Intel® CPUs. This behavior seems to be related to the split “efficiency” and “performance” cores on newer processors.
Mitigation Actions
Try restarting the CODESYS* Linux* runtime:
$ sudo systemctl restart codesyscontrolVerify that the CODESYS* Linux* runtime is active (running):
$ sudo systemctl status codesyscontrolUse the kernel boot parameter
isolcpusto isolate the “efficiency” cores.Enable

Limitation #6 - Fail when calling Intel Level0 API¶
Enable Intel® Level Zero and OpenCL™ Graphics Compute Runtime may not start correctly on Intel® Atom™ x3000 Series [Apollo Lake] Gen9 Graphics and Intel® Atom™ x6000 Series [Elkhart Lake] Gen11 Graphics that do NOT support Intel oneAPI Level-Zero.
$ ze_info
When Intel® oneAPI Level-Zero is NOT supported by Intel® HD Graphics user gets the following error message:
ze_info: ./samples/ze_info/main.cc:382: int main(int, char**): Assertion `status == ZE_RESULT_SUCCESS' failed.
Mitigation Actions
Use ONLY Intel® OpenCL HD Graphics APIs to optimize application using Intel® Atom™ x3000 Series [Apollo Lake] Gen9 Graphics and Intel® Atom™ x6000 Series [Elkhart Lake] Gen11 Graphics
