Read/write fail in USB PVND (no RTOS) on RA4M2

Hello wonderful community,

I am trying to implement a custom USB peripheral with an RA4M2 MCU on a custom board. This means I need a USB PVND stack.

Starting point:

- I have a USB PCDC demo running on my board (without RTOS)

- Switched to the PVND class using the standard example suite from FSP 4.3.0 pack. I adapted it for non-RTOS and for my own descriptor (cloned from a different board)

- The device is recognized by the Device Manager similarly to the other board and looks the same in USB analyzers.

- Using EP1 for bulk in/out. The DeviceAddress is different, but I assume that is dynamically allocated by the USB Host and does not matter.

- I use a PC driver that writes and then reads test data, and the driver itself works on the other board, so I consider the PC side ok.

Now comes the problem: none of the read/write operations succeed. Things I checked:

- The "usb_pvnd_write_complete" or "usb_pvnd_read_complete" never get called. They are the ones responsible to signal an event to the polling loop by calling "setEvent".

- Also looking into "usb_pstd_interrupt_handler", there are some requests coming (setup transaction and DVST) but never for BRDY, BEMP or NRDY, which I assume are required for read/write operations.

- When writing to the host, the second write command gives "BUSY", so the first write did not go through.

If someone can help, please let me know what other info/code fragments I can provide, or where can I do more digging.

Thank you in advance!

  • Sure, I am attaching the config XML and a screenshot of the basic USB stack properties.

    It's the same config as the USB PCDC demo that works. I just replaced the PCDC with a PVND and also added a timer.

    Both PCDC and PVND are no-RTOS configs, so I assume the same XML should work. Plus the fact that the USB gets recognized should mean the basic HW config is ok.

    I would also exclude the polling loop as a culprit because the USB setup works and the problem seems to be a missing read/write event even before my polling loop.

    Best regards,

  • Hello again,

    I assume that you have changed also the code from usb_pcdc example since these APIs are used for usb_pvnd  

    Could you also share your code with us?

    Thank you!

    Best Regards,

    IK

  • Hi,

    Yes, here's the "manual" part of the code. It does indeed use the PipeRead/PipeWrite functions.

    #define APP_ERR_TRAP(err)        if(err) {\
            SEGGER_RTT_printf(SEGGER_INDEX, "\r\nReturned Error Code: 0x%x  \r\n", err);\

    //		err = R_USB_PipeWrite(&g_basic0_ctrl, wBuf, 3u, bulk_in_pipe);

    //	}

    I am trying to get a minimalistic concept running, just initializing USB and then running "process_usb_event" in an infinite loop. The fact that USB device is correctly recognized tells me the problem is not in Init, so I didn't include that part. The Read part is not implemented, because the READ/WRITE switch cases are not even hit so far.

    I am trying to make it as similar to the PCDC demo as possible. Maybe it's easier if you can confirm the following:

    1. Is PVND driver designed to work correctly in non-RTOS mode ? I found a non-RTOS example for PCDC, but not for PVND, that's why I'm asking

    2. Does the PVND setup need different FSP config than the PCDC ? Does it need any additional or different function calls (other than the PileRead/PipeWrite change?)

    3. ZLP packet logic should not be a blocker, because the issue appears even when first reading from USB, and ZLP packet is not relevant in this case, correct ?

    4. Any suggestion where to put breakpoints and check data or control flow ?

    5. Do you by any chance already have a non-RTOS PVND example code ?

    Thanks!

  • Hello,

    Apologies for the delay!

    Unfortunately we do not have an non RTOS example with usb_pvnd, there is only an RTOS example which is using 2 different RA MCU device. The one device runs usb_pvnd example and the other is running usb_hvnd example. The driver can be used and with no RTOS projects.

    I would suggest to you to take a look on the documentation provided for usb_pvnd module of FSP. 

    There is also an example of code here which shows how to use it with RTOS and no RTOS. Please check the link below:

    https://renesas.github.io/fsp/group___u_s_b___p_v_n_d.html

    Hope it helps!

    Best Regards,

  • Thank you for the suggestions. I changed my test procedure and by luck I managed to detect some USB activity.

    Reads and writes somehow work, but not as expected. I don't get any USB_STATUS_READ_COMPLETE event from R_USB_EventGet function when there is new data in the pipe. But it works if I periodically call the PipeRead. Most of the time it'll return an error, but when there is data, it returns it correctly.

    Is it meant to be like this for PVND ? Do I have to use another function to check if there is incoming data ?

    I should mention I am using 2 pipes, both configured on EP1 (IN and OUT) in bulk mode. Could this be a problem ?

    -LATER EDIT- it seems that I was using the read/write functions wrong. I need to call read in order to listen for new data, not after the data is received. This solved it.

    Best regards,

    Alin
