Bollywood Songs R May 2026

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?

Whether you're a fan of old-school Bollywood or new-age fusion, there's something for everyone in the world of Bollywood songs. So go ahead, press play, and let the music transport you to a world of joy, love, and magic!"

"Bollywood songs are an integral part of Indian cinema, adding magic to every film. With their catchy tunes, memorable lyrics, and energetic beats, these songs have become a staple of Indian popular culture. From classic hits like 'Mast Magan' and 'Kal Ho Naa Ho' to recent chartbusters like 'Senorita' and 'Tuje Dekha To', Bollywood songs have a way of making us sing along and dance.

The best part about Bollywood songs is their diversity - they range from romantic ballads to peppy dance tracks, and from soulful melodies to quirky, offbeat numbers. The lyrics often tell a story, paint a picture, or evoke a feeling, making them relatable and memorable.

Many iconic Bollywood singers like Lata Mangeshkar, Asha Bhosle, and Mohammed Rafi have contributed to the richness of Bollywood music. Today, singers like Arjit Singh, Shreya Ghoshal, and Neha Kakkar continue to mesmerize audiences with their soulful voices.

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.
