Hi all,
I am trying to integrate some speech codecs (using Codec Engine) on
DM355 and have the following query.
Codec Engine uses CMEM to allocate the memory for all components(local
or remote), however there is an option
available which specifies the usage of heap memory(The option is given
below)
algSettings = xdc.useModule('ti.sdo.ce.alg.Settings');
algSettings.useHeap = true;
Can anyone please clarify as to what this option is for?
Once I select this option will the memory I access be from CMEM or heap?
Also if the memory I access through any local component is from heap
,then will it be cached(taking into consideration that ARM memory is
cached)?
Thanks in advance,
Divya

Hello Everyone,
I'm trying to run a wifi dongle on the Davinci board, with the
requirement that the transmission power is controllable.
I started by getting the ZyDas dongle to work on the board, but the
power wasn't controllable. In any platform, in fact.
So I moved on to the D-Link DWL-G122 (rev.C1).
The tx power IS indeed possible to control in Ubuntu, but I can't make
it to work on the Davinci.
I followed the steps written by the people at:
wiki.davincidsp
http://wiki.davincidsp.com/index.php?title=Davinci_USB_WLan
which state that they got the serialmonkey RT73 CVS driver to work in
the exact same hardware as mine
(Davinci ARM board & D-Link dongle mentioned above)
but the firmware always fails to load.
...I thought the problem might be due to dodgy support of USB2.0 in
Davinci.
So I inserted a USB1.1 hub in series with the wifi dongle to make it
work in 1.1 mode.
Now I'm using a script - 'loadfirmware' - to "feed" the driver with the
firmware, depending how the dongle is attached (with hub / no hub):
loadfirmware:
#! /bin/sh
sleep 2
DEV=`ls -d /sys/class/firmware/1*`
echo Loading firmware into $DEV
echo 1 > $DEV/loading
cat /rt73.bin > $DEV/data
echo 0 > $DEV/loading
it does get me a bit further, I insert the module with "(insmod rt73.ko
debug=2 &); ./loadfirmware", and I get:
[EMAIL PROTECTED]:/# (insmod rt73.ko debug=2 &); ./loadfirmware
rt73: init
rt73: idVendor = 0x7d1, idProduct = 0x3c03 Loading firmware into
/sys/class/firmware/1-1.1 [EMAIL PROTECTED] to load firmware!
78:/#
[I believe the overwritten prompt is due to the scripted "sleep"]
But then, when I try to do 'ifconfig up', I get:
[EMAIL PROTECTED]:/# ifconfig wlan0 up
rt73: driver version - 1.0.3.6 CVS
rt73: Firmware not load
ifconfig: SIOCSIFFLAGS: Input/output error
(and 'ifconfig' lists in wlan0 "HWaddr 00:00:00:00:00:00")
- What am I doing wrong?
Thanks in advance,
David

Manas,
The current version of LSP 1.20 for DM355 does not support SDIO. Similar
to the patches 38 - 45 against LSP 1.10 for DM6446, we will be releasing
SDIO patches for DM355 against LSP 1.20. These patches would be
available some time in early July.
Thanks
Sneha

Subject: SDIO WiFi support fro DVEVM DM355
Hi,
I want to use Wifi card with SDIO interface of my DM355 board.
Can the SD driver given with the board(1.2Version) will support this. I
found in the "LSP 1.20 DaVinci Linux Drivers" that it does not have SDIO
driver in this release.Anybody has implemented this ?
Thanks
MANAS
