Severance S01e04 1080p Web H264-glhf Online

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?

The mysterious figure, Lumon, continues to exert its influence over the characters, raising questions about the true nature of their employment and the motivations behind the severance procedure. The show's use of symbolism, particularly the recurring motif of the Lumon logo, adds to the sense of unease and foreboding.

One of the standout aspects of this episode is the character development of Helly Riggs (Brittany Miller). Her interactions with Mark and the other characters reveal a deep-seated desire for connection and understanding. The actress brings a sense of vulnerability and relatability to her portrayal, making it easy to empathize with her plight.

The episode's climax features a tense confrontation between Mark and his "innie," which serves as a catalyst for the character's growing self-awareness. The scene is expertly choreographed, with the editing and sound design working in tandem to create a truly unsettling atmosphere.

The episode begins with a gripping scene, as Mark Scout (played by Adam Scott) navigates the complexities of his severed life. The use of lighting and camera angles creates a sense of unease, mirroring Mark's growing discomfort with his situation. The writers skillfully balance the comedic elements, courtesy of Dylan G. (Zach Cherry), with the darker themes, making for a captivating viewing experience.

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.
