DM3730 MUSB

Other Parts Discussed in Thread: DM3730

Hi,

We are using MUSB present on DM3730. It is configured for OTG functionality. When MUSB is operating as peripheral if we perform Bulk In transfer the TxPacketReady bit never gets cleared and no interrupt is generated on this endpoint. Hence we are stuck with using the MUSB in peripheral mode.

Can you please suggest how to debug this and when the Bulk In endpoint will not be able to make successful transfer?

Regards,

GSR

    Hi GSR,

    I recommend you as first step of debugging the issue to post the log of logcat. The next step of debugging will be adding of some log messages in the source. It would be useful for me to specify are using custom board or some TI's development board and the software distribution and kernel version which you are using for further investigation of the issue.

    Hi Tsvetolin Shulev,

    Thank You for the reply.

    We are using a customized hardware. I will post the register dump as soon as possible as we are not using Linux.

    Mean while please do let me know if you would like to see any specific registers other than the USB OTG Controller registers.

    Regards,

    GSR

    OK, let's start with USB OTG controller registers.

    Hi Tsvetolin Shulev,

    Below is the dump that I have when transfer against IN Transfer Is failed on EP1.

    The description of the registers is from the source code as we do not have access to OTG TRM.

    Thank You for your time.

    Hi GSR,

    Could you check whether your USB controller is configured as description in the TRM section 22.1.5.4.3 High-Speed USB Controller in Peripheral Mode?

    http://www.ti.com/lit/ug/sprugn4r/sprugn4r.pdf

    I have need of some additional information. Could you dump 256 bytes of the RAM starting from physical address 0x480ab000 when the musb otg is already configured (Paste the dump in binary file if it is possible).

    Hi Tsvetolin Shulev,

    We are following the initialization sequence from the section 22.1.5.4.4 as we have to use the OTG port for Host and Device functionality.

    The register dump for the first 256 bytes from 0x480AB000 is given below.

    Hi GSR,

    I'm sorry but I have missed to explain you that I have need of dump when the problem is happen. Could you make a new one when the problem is happen? As I analyze the dump it is taken when the USB cable is unplugged. Am I correct?

    Hi GSR,

    The issue seems very complicated. Are you using some public source code for USB driver and can I see it?

    Hi,

    Thank You for the reply.

    Can you let me know on the below two points.

    1. We are programming TxFIFOSZ, RXFIFOSZ, TXFIFOADD, RXFIFOADD with the following values 4, 4, 0 and 32 when index register is programmed with 0. But after programming if we read all the above registers it is showing a value of 0 only. Can we program TXFIFOSZ, RXFIFOSZ, TXFIFOADD and RXFIFOADD when INDEX register is set to a value of 0?
    2. On some host machines we are seeing a unrecognized USB Device error. When we used catalyst protocol analyzer to debug the issue the issue is not reproducible.
    Can you help me on the above points?
    Regards,
    GSR

    Hi,

    I am observing the following behavior.

    The device get enumerates at High speed. On EP0 interrupt the first packet it reads from FIFO is

    0x80 0x06 0x100 0x00 0x40, in response to this setup packet the device firmware writes the following 18 bytes data (0x12 0x01 0x00 0x02 0x00 0x00 0x00 0x40 0x5e 0x04 0xce 0x00 0x00 0x00 0x01 0x02 0x00 0x01) to EP0 FIFO and sets TX PACKET READY. It also clears SEND STALL and SENT STALL Bits.

    After 674mS the host again sends a SETUP Packet. The setup packet is same as the above and the device firmware again prepares the 18-bytes length packet given above. 

    After 674mS the host again sends the same SETUP packet and the device firmware prepares the 18-Bytes response packet and writes to FIFO.

    It appears to be the SETUP packet response is not getting transferred from the device to host.

    Can I look at any specific registers to find the reason why the packet is not getting transferred from the device?

    The value of CSR0 is 0xA after setting TxPacket Ready and DATAEND.

    In this case we are getting a new setup packet after programming a 18-Byte GetDescriptor Response. What will happens to that data after receiving the Setup Packet. What about the TXPACKETREADY BIT set in CSR0 register?

    Regards,

    GSR
