Where are the host controller drivers? #5

Closed dreiss closed 3 years ago

dreiss commented 3 years ago

The documentation overview ( https://docs.microsoft.com/en-us/azure/rtos/usbx/overview-usbx ) says "Azure RTOS USBX supports proprietary discrete USB host controllers from Atmel, Microchip, Philips, Renesas, ST, TI, and other vendors". However, under common/usbx_host_controllers, I only see drivers for OHCI and EHCI. Are there drivers (and, ideally, sample code) for using USBX Host on STM32F4 or Microchip SAMD51?

Taranus commented 3 years ago

Same question here, as we would like to use USBX in a SAM D21 device.

Also, in general, who is responsible for the ports of the Azure-RTOS components? Having the components/framework source code is nice, but if we have to write the BSP/glue code there is no way to reduce the time to market when using a pre-licensed hardware.

Hi all, we have a handful of host controller drivers available - I'm not sure why we haven't posted them on github yet. If you look at the example projects in the samples repo you can find drivers for ST and SAM E54. I'll find out more about other host controllers.

Thanks for the pointer! In the "stm32f746g-disco" sample, I found the source file ./stm32cubeide/sample_usbx_host_mass_storage/usbx_host_controllers/ux_hcd_stm32_initialize_fscore.c, which appears to be what I would need to run the OTG_FS peripheral in the STM32F411 in host mode (though I haven't tried it out yet). It would be awesome to see this file added to the main USBX repository, and even more awesome to see a demo of using STM32F411 in host mode, since the middleware supplied by the chip manufacturer does not support USB hubs.

There is a demo of host mode for 746 - see sample_usbx_host_mass_storage. The 411 device is probably pretty similar.
