<DIV><FONT face=Arial size=2>Hi All</FONT></DIV>
<DIV><FONT face=Arial size=2>Pardon the intrusion if this is not the correct way
to get the relevant information, but I am relatively new to kernel
hacking.</FONT></DIV>
<DIV><FONT face=Arial size=2>Anyway here goes my question:</FONT></DIV>
<DIV><FONT face=Arial size=2>I am getting a Freescale MPC8343 based board up and
running and have been using the BSP (with patched 2.6.11 kernel) release by
Freescale with great success.</FONT></DIV>
<DIV><FONT face=Arial size=2>However when I tried to use the USB ISO
transactions it seems to be non functional. I have connected a known good
working codec (tested on my PC's usb) and tried to access it via the low level
sound driver (/dev/dsp) but it only creates garbled noise. </FONT></DIV>
<DIV><FONT face=Arial size=2>In the meanwhile, I have noticed that the official
kernel release 2.6.17 also start supporting the MPC834X platform and would
rather like to persue that avenue to get my problems addressed (hopefully).
</FONT></DIV>
<DIV><FONT face=Arial size=2>I have downloaded the latest 2.6.17 kernel and got
it going with the configuration for MPC834x_sys, with relation to
booting and ethernet comms. </FONT></DIV>
<DIV><FONT face=Arial size=2>However there are clearly no provision in the USB
driver for setting up the usb clocks and ports (which is of course MPC834x
specific). </FONT></DIV>
<DIV><FONT face=Arial size=2>I have tried to hack it by inserting approriate
code form the 2.6.11 freescale kernel but with very little success.
</FONT></DIV>
<DIV><FONT face=Arial size=2>On inspection of the 2.6.11 kernel from Freescale
I have also noticed that the USB core drivers were heavily modified
around DMA buffer management, although the 2.6.17 had no such hacks in place.
</FONT> </DIV>
<DIV><FONT face=Arial size=2>My question simply relates to the status of the
MPC834x implementation on the 2.6.17 kernel in so far that it is operational and
being tested on hardware platforms. Could you please direct me to the
persons(s) who have experience with this platform ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Regards</FONT></DIV>
