Vmxvcp-17.1r1.8-domestic-vcp Download ((full)) File

Hi all,

I'm using ST's CubeMX implementation on a F4 discovery board. I use ST's USB middlewares with FreeRTOS.

When I get a special OutputReport from PC side I have to answer nearly immediately (in 10-15 ms). Currently I cannot achieve this timing and it seems my high priority tasks can interrupt the USB callback. What do you think, is it possible? Because it's generated code I'm not sure but can I increase the priority of the USB interrupt (if there is any)?

Thank you, David

10 to 15 ms is very slow, so I'm sure its possible.

Where is the USB callback function called from? If it is an interrupt then it cannot be interrupted by high priority RTOS tasks. Any non interrupt code (whether you are using an RTOS or not) can only run if no interrupts are running.

Without knowing the control flow in your application its hard to know what to suggest. How is the OutputReport communicated to you? By an interrupt, a message from another task, or some other way?

The callback which receive the data from PC is called from the OTGFSIRQHandler (it's the part of the HALPCDIRQHandler function). I think the problem is SysTickHandler's priority is higher than OTGFSIRQHandler and it's cannot be modified, but the scheduler shouldn't interrupt the OTGFSIRQHandler with any task handled by the scheduler. Am I wrong that the scheduler can interrupt the OTGFS_IRQHandler?

Official software images for Juniper vMX must be downloaded directly from the Juniper Networks Support Portal Requirements

17.1R1.8 is an older, yet stable release frequently used for testing specific features or for labs built upon older EVE-NG templates.

: Look for official release notes from VMware. These documents usually provide:

After downloading VMX-VCP-17.1R1.8-Domestic-VCP, follow these steps to install and set up the software:

Download the official Juniper vMX vCP Appliance Template from the GNS3 marketplace. Import the template into your GNS3 GUI workspace.

The em1 (vCP) to eth1 (vFP) link is crucial. If they are not linked, the router will not form a forwarding FPC (Forwarding Packet Controller).

This article provides a comprehensive overview of the vmxvcp-17.1r1.8-domestic-vcp download, a specific software package for Juniper Networks' virtualized MX (vMX) router platform.

The vMX 17.1R1.8 environment demands specific resources to run optimally: Minimum 1024 MB (1GB). vCP Disk: 1 qcow2 image.

Successfully deploying a vMX router is a significant step toward building a powerful home lab or enterprise network simulation. This guide provided the necessary steps to deploy the "vmxvcp-17.1r1.8-domestic-vcp" identifier. For a more robust and supported experience, always consider acquiring your software through official channels like a Juniper evaluation license.

Create the required directory structure: /opt/unetlab/addons/qemu/vmxvcp-17.1R1.8-domestic-VCP/ .

The key takeaway is that the "domestic" tag likely differentiates this version from an "export" version, which may have cryptographic restrictions. The "VCP" suffix clarifies that this is the Control Plane virtual machine image.

The image is a critical component for network engineers, architects, and students looking to emulate, test, or train on Juniper Networks technology. This image constitutes the Virtual Control Plane (vCP) for the Juniper vMX (Virtual MX Series 3D Universal Edge Router), designed specifically for virtualized environments like GNS3 , EVE-NG , or VMware ESXi .

Thank you for the answer, I think I'm a bit confused with the Cortex ISR priorities :-) What I can observe is if I use a much higher osDelay in my high priority task I can respond for the received USB message much faster. This is why I think tasks can mess up with my OTG interrupt.
