For the last week, I've been trying to get asynchronous USB Audio 2.0 to work.I have dissected the descriptors from a Focusrite Scarlett 2i2 and crafted my own with the usb audio 2.0 docs at hand. I've modified the CubeF4 audio example and kept most ...

I'm converting the CubeMX usb audio device example to be audio class 2.0 compliant, with high-speed external phy.I have to implement a feedback endpoint to report the current number of samples per microframe. For this, I have tim2 set up as external ...

I’m creating a custom USB HS DFU bootloader for my STM32F429 project, using arm-none-eabi-gcc together with the CLion IDE. I’m having trouble jumping to the application code from the bootloader.The CLion project consists of a bootloader target and a ...

I'm working on a custom boot loader for a STM32F429, where I want to reserve the second of the first four 16K flash sectors for user data. Because the vector table has to start at 0x08000000, the memory layout would look like this:0x08000000 - isr ve...

I'm developing an STM32F429-based high-speed USB audio device that uses a Microchip USB3320 external PHY and would benefit from a DFU mode. Is there an example available anywhere for such a configuration?The default bootloader present in system memor...

What worked for me is to add STM32 Cube MX to list of the apps that get allowed "full disk access" under System Preferences -> Privicay & Security -> Full Disk Access.

No, sorry. Neither ST or anyone else has stepped up to provide either hints to continue or a concrete solution. I haven’t tried to get it working for another 2 years.. still like to get it working though. What is your specific problem / use case?

Hi Jacob,I'm experiencing the same issues. I'm writing a asynchronous usb audio 2.0 driver for STM32F429 with external HS USB PHY and trying use a Iso IN endpoint to send back actual sample clock feedback. My endpoint should receve a in-transfer only...

My hunch was that this somehow relates to the external PHY. I tried accessing the PHY's TX_BOOST register by accessing undocumented(!) registers using the code discussed in this thread, but that wasn't it.I've turned my board into a High Speed HID de...

I just wanted to say that I've ported the USB_ULPI_Read and USB_ULPI_Write functions to my project that uses a STM32F429 and a USB3320 Phy.. the code works! I can access the various registers and they return expected values.. How bizarre that this is...
