Hi Stefan,<br><br>Also in the SETUP stage where I have set my packet size as 1, as I treat
each of this 3 stages (SETUP, DATA and STATUS) as three different
stages/transactions, I find that the "Non-Periodic Transmit FIFO/Queue
Status Register" read as soon as I write to the "Non-Periodic Transmit
FIFO Size Register" as "0x10500fa". Before writing the value is
"0x80100". Is it fine that the bit 7 which defines the termination
of channel a right thing to happen?
Secondly since i am writing 2 bytes to the FIFO why should the "Non-periodic TxFIFO Space Avail (NPTxFSpcAvail)" bits of USB0_GNPTXSTS be 0xfa?<br>
<br>The FIFO to which I write:
<br>*USB0_GRXFSIZ - 0x213 USB0_GNPTXFSIZ - 0x1000213*
<br>The above setting mean that my Non-Periodic Transmit register starts at
0x213. So I write my data (8 byte SETUP Token Data) in the following way:
<br>- Write the first 4 bytes to the starting adress of 0x1000 since I
am using Channel 0 --- (*(volatile unsigned *)(DHc->base + 0x1000 +
(bEnd * 0x1000) + 0x213 + fifo_address_offset))=*((volatile
unsigned *)pSrcBuf);
<br>- Then increment the "fifo_adress_offset" by 4 and write the next 4 bytes.
<br>
<br>I think that there is some problem in the SETUP (Token) Stage. Can you
please pass any pointers over this?<br><br>Regards;<br>Aadish<br><br><div class="gmail_quote">On Wed, Feb 25, 2009 at 6:09 PM, Adish Kuvelker <span dir="ltr"><<a href="mailto:adish.kuvelker@gmail.com">adish.kuvelker@gmail.com</a>></span> wrote:<br>

</div></div>Are you talking about the 405EX internal USB OTG controller (Synopsys DWC) or<br>
some other OTG controller?<br>
