How can I use UsbX and FileX without ThreadX

[JulInnovel]

Hello all,

Split from this thread:

I'm using an STM32U5G9 and I need to read files from a USB stick.

I don't want to use ThreadX because I have to keep this application small.

How can I achieve this if UsbX and FileX are supposed to be used only with ThreadX and not in standalone mode?

 

Thanks for your help.

Best regards,

Julien

Hi @JulInnovel 

USBX Host MSC standalone operation is not supported with FileX due to a dependency that requires the ThreadX context. When USBX Host is used in standalone mode, FileX cannot be supported, as enforced by a conditional definition in ux_host_class_storage.h that disables FileX support in standalone mode.

Hi,

 

My original question was: how can I use USBX and FileX to read files from a USB stick (host mode) in standalone mode (so without ThreadX)?

It does not seem to work properly. I tried using the old ST USB stack with FatFS (https://github.com/STMicroelectronics/stm32u5-classic-coremw-apps) instead, and now everything seems to work fine.

 

Best regards,

Julien
