Is there a USBX HOST PIMA reference code ?

[111llll111]

Hi ,

I need to use STM32H573 as a USB host to read and write Android phone files.

I registered the pima class, connected to the mobile phone to set the MTP function, enumeration failed, but the PTP function can be successfully enumerated.

I have not used PIMA function. What function code should I use to read and write files on my phone?

Do you have the usbx host pima reference code?

Thanks!

Define UX_PIMA_WITH_MTP_SUPPORT and compile again to enable MTP support.
PIMA manages files as objects, you can use object functions to access your files. Usually you should open a session, get object information, open it, read/write it then close it.

Hi

MTP mode still fails enumeration, PTP enumerates successfully.

I opened the macro definition UX_PIMA_WITH_MTP_SUPPORT ,But this macro definition only seems to work on the USB DEVICE side?

Hi CQ，

I would like to confirm whether these are the only file formats supported by MTP?

If I want to transfer zip files or bin files, is it not supported?

Thanks！

The upper code is actually defined by PIMA 15740:2000.
I'm not sure if how your device reports zip or bin files, if they can be referenced in undefined code or some other codes you can use them.

Hi CQ，

Can you help us see why the MTP enumeration fails, but the PTP enumeration succeeds?

[xiaocq2001]

Do you have traces for the enumerations to analyze?
