Hello ,
Thanks David for your reply. You talked a 3 wire connection of stm32
Discovery board with SM1000 to listen hts1a.raw. Can you specify the exact
points for connection between stm32 and sm1000.
Thanks in advance
Nauman

You're right Steve, I even blogged on it:
http://www.rowetel.com/blog/?p=3427
This bit is a slightly damped 2nd order system for me (rings a bell):
"This work took me about an hour of creative thinking (the fun bit) and
several days of implementation pain, off by one errors, fighting to
understand filter memories (again), and tracking down differences
between the Octave and C versions."
That ratio of 1% inspiration/99% perspiration .....

Hi all,
I have downloaded the code from svn and followed the instructions in
stm32/README. All steps went well without any error. After making stlink, I
copied hts1a.raw in stlink folder.
While running sudo ./st-util -f /home/lab/codec2/stm32/stm32f4_codec2.elf I
have got the following error.
-f arg; /home/lab/codec2/stm32/stm32f4_codec2.elf
2015-07-28T17:02:15 WARN src/stlink-usb.c: Couldn't find any ST-Link/V2 devices
Any suggestions ?
My sm1000 is in debug mode (Pressed PTT then powered up then PTT released).
dmesg shows me following
[98392.925109] usb 1-1.3: Product: STM32 BOOTLOADER
[98392.925110] usb 1-1.3: Manufacturer: STMicroelectronics
[98392.925111] usb 1-1.3: SerialNumber: 335838523233
Means device is connected.
Thanks in advance
Nauman

Are you using a ST- LINK Programmer? Looks like that device is a STM board
and its connecting to the STM bootloader.

Do you have the STLINK_DEVICE environment variable defined properly to the
USB port detected after the 'dmesg'.

Use the 'lsusb' to get the bus and device address probably.
STLINK_DEVICE=001:004; export STLINK_DEVICE
For BUS 1 Device 4, or whatever associates with the USB port desired.
I looked at the code and if the variable is not defined it just goes
along merrily until it blows up somewhere down the line.
Just an idea...

To use st-util, gdb, and the stdio semi-hosting library, you need a
Discovery board and 3 wire STLINK connection to the SM1000.
Or you can use a Discovery board stand alone to run many of the unit
tests in codec2-dev/stm32.
Alternatively you can simply flash the SM1000 over USB using the boot
loader, as described on the SM1000 page. However in this case you can't
use the semi-hosting facility, e.g. fread/fwrite required bymany of the
programs in codec2-dev/stm32.
Cheers,
David
