If Target development tools run under Windows, why use Linux as Tools O/S?Maybe it is time to rethink this for our legacy and non-audio customers.

•Got uImage kernel to boot off WinXP using Pumpkin TFTP server•Got NFSAxe to act as NFS Server on WinXP•Got MV-Pro to build uImage kernel in WinXP in Bash and DevRocket (with some path modification)•Used DevRocket Debug on WinXP and GDBserver (with –attach PID) on DVEVM to build/debug decode (AAC) •Got ARM and DSP open in CCS (though SD drivers seems more stable then BH) with Linux running.

•If LAN then got Corp network access but some delay and certain local resources (i.e. DevRocketTarget filesystem might not work)•If WAN/Internet then local router with MAC address filtering isolates from Corp network, but tough to use Outlook, SNAP servers, and other network resources (turn off DHCP, though turning back on will require a Router hard reset).

•Build Config with C++ View in C++ Perspective with makecommand.

MV-Pro DevRocket - WinXP

•Debug Config with C++ View in C++ Perspective using remote GDBdebugging

14

•In DevRocket workspace File->New->Kernal Project does not show an LSP)•MontavistaZone says to run in a Bash shell:

•/opt/montavista/<edition>/host/bin/mvl-setup•Or better yet (next slide)

DevRocket – If no LSP Installed

15

•In DevRocket workspace for LSP under•C:\mvcyg4.0\home\a0321791\montavista\devrocket2.0\workspace\uImageDevRocketLSP120

•Key is (if File->New->Kernal Project does not show an LSP), then File->Import->External C/C++ Project

DevRocket – Import for LSP

•Will take almost ½ to 1 hour to import•Turning off the indexer under “Project->Properties->C/C++ Indexer->Uncheck enable” can speed up.

16

•Add paths in Bash shell by:•Type:

PATH="/opt/dvevm/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le/bin:/opt/mv_pro_4.0/montavista/pro/bin:/opt/mv_pro_4.0/montavista/common/bin:$PATH“

•Or make a bash.bashrc file in C:\mvcyg4.0\home\a0321791with this line and from Bash shell type:source ~/.bashrc

•Test Path by typing:set

•To get the output:PATH=/opt/montavista/pro/devkit/arm/v5t_le/bin:/opt/montavista/pro/bin:/opt/montavista/common/bin:/usr/local/bin:/usr/bin:/bin:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS

…•Build uImage by:

make ARCH=arm CROSS_COMPILE=arm_v5t_le- uImage

•Bash shell is nice to debug build by writing outputs to file such as:

MV-Pro Bash Shell – Build uImage kernel(Optional for command line build/debug)

make ARCH=arm CROSS_COMPILE=arm_v5t_le-uImage > output.txt

make ARCH=arm CROSS_COMPILE=arm_v5t_le-uImage 2> err.txt

Also get to the entire WinXP HDD by:cd /cygdrive/c/mvcyg4.0

Menuconfig has issues with kconfig:make ARCH=arm CROSS_COMPILE=arm_v5t_le-menuconfig > yoyo.txt 2>&1

So set in VMWare a copy .config file

17

•Check DevRocket Build Environment under DevRocket Project->Properties->Builder Configuration->Environment:

MVHOSTTOOLCHAIN=/opt/montavista/pro/binMVCYGWINUSRBIN=C:\mvcyg4.0\usr\binMVHOME=/opt/montavistaMVCOMMONTOOLCHAIN=/opt/montavista/common/binMVCYGWINBIN=C:\mvcyg4.0\binMVTARGETTOOLCHAIN=/opt/montavista/pro/devkit/arm/v5t_le/bin

DevRocket – Build Environment

18

•DevRocket Project Properties->Builder Configuration->Build->Command line •Console with build uImage kernel info •System.map file gives you driver functions like davinci_set_samplerate() for reference (address wrong due to MMU) but symbol info and source code pathnames good.

DevRocket – Build uImage kernel

19

DevRocket – Import for Decode AAC demo

•Will take almost ½ to 1 hour to import•Turning off the indexer under “Project->Properties->C/C++ Indexer->Uncheck enable” can speed up.

•In DevRocket workspace for LSP under•C:\mvcyg4.0\home\a0321791\montavista\devrocket2.0\workspace\DecodeAAC

20

Decode AAC demo – Rules.make Environment

•Rules.make needs to be modified to match the particular PC directory environment. •Start with:•C:\mvcyg4.0\home\a0321791\montavista\devrocket2.0\workspace\DecodeAAC•Rest of the modifications on the next slide

•To prep for remote debugging on target (TCP/IP Address 158.218.121.65)[email protected]:~# mount 158.218.121.89:/c/mvcyg4.0/home/a0321791/montavista/devrocket2.0/workspace

•Teratermfor uBoot

•PumpKIN for tftpserver

•NFSAxe for NFS Server

•WinXP Host TCP/IP Address is 158.218.121.89

23

DevRocket Remote Debug (GDB) of Decode AAC demo

•To prep for remote debugging in DevRocket, •Go to Project->Debug->Debugger Tab•Make sure Debugger= GDB Server •GDB Debugger=arm_v5t_le-gdb•Connection=TCP•IP address=IP of Target/DVEVM (158.218.121.65)•Port #=100000

24

DevRocket Remote Debug – Target Setup

To prep for remote debugging on target (TCP/IP Address 158.218.121.65):

•Mount WinXP NFS Server (TCP/IP Address 158.218.121.89) to Target [email protected]:~# mount 158.218.121.89:/c/mvcyg4.0/home/a0321791/montavista/devrocket2.0/workspace /misc/winxpnfs

•Run copied version of decoded app (to avoid file access conflicts) along with .sh [email protected]:~# cd /misc/winxpnfs/decodeaac/demos/decode/[email protected]:/misc/winxpnfs/decodeaac/demos/decode/debug# ./[email protected]:/misc/winxpnfs/decodeaac/demos/decode/debug# cp decoded [email protected]:/misc/winxpnfs/decodeaac/demos/decode/debug# ./decoded2 -a data/sounds/davincieffect.aac gdb &[1] [email protected]:/misc/winxpnfs/decodeaac/demos/decode/debug# Decode Debug: NTSC selectedargc = 4argv[0] = ./decoded2argv[1] = -aargv[2] = data/sounds/davincieffect.aacargv[3] = gdbDebug is argv[3]gdb(Could not get Project->Debug->(x)=ArgumentsTab to work for argc/argv. This was better,)

•Run gdbserver (in /usr/bin) with attach to decoded2 [email protected]:/misc/winxpnfs/decodeaac/demos/decode/debug# gdbserver host:10000 --attach 1125Attached; pid = 1125Listening on port 10000(gdbserver host:10000 ./decoded2 -a data/sounds/davincieffect.aac nogdb dspoff &Will also work but seems to close the targer Putty window when done)

•Added the gdb switch to decode to determine run time whether to debug or not./decoded2 -a data/sounds/davincieffect.aac gdb & - debug./decoded2 -a data/sounds/davincieffect.aac nogdb & - no debugSee main.c code in next slide

25

DevRocket Remote Debug •GDB Server running on Target (TCP/IP Address 158.218.121.65)for Port 10000 with PID 1125

•DevRocket Breakpoint at line 325 of main.c•If you add ijoe=0 to the expressions tab and “resume”, you can continue the debug•Single step was not working but Resume to next Breakpoint OK

26

(Trace and) SoC Analyzer (And LTT)



For Trace debug command line does not work on WinXP:[email protected]:~# CE_DEBUG=2 ./decoded2 -a data/sounds/davincieffect.aac nogdb [email protected]:~#CE_TRACE="*=01234567" ./decoded2 -a data/sounds/davincieffect.aac nogdbdspoff

But adding into code does in main.c:// jg 9/10/08 - From CE FAQGT_set("*=01234567");

To prep for LTT and SoC Analyzer on target, need to build on Host:make ARCH=arm CROSS_COMPILE=arm_v5t_le- menuconfigBut this causes build errors on WinXP due to:

1. Kconfig “help” heading can’t take space (manually removed)2. Other build error with ?

•Workaround by running menuconfig in VMWare and copy .config to:/home/a0321791/montavista/devrocket2.0/workspace/uImageDevRocketLSP120

•In make menuconfig got to add relayfs and then on target: [email protected]:~# mount relayfs /mnt/relayfs

•Then on Host after running:[email protected]:~#./thttpd -c "/cgi-bin/"And using DVT-DM644xSOCAB.exe is Version: 1.0.0, got http error with:command=killall+tracedaemon%3Brm+/tmp/trace.trace+/tmp/proc.txt+/tmp/proc_thread.txt+/tmp/output.txt%3B/bin/tracedaemon+-b524288+-n4+-eSTART+++++++-eSCHED+++-ePROCESS+-eFS++++++++/tmp/trace.trace+/tmp/proc.txt+%3E/tmp/output.txt%3B/opt/dvt-dsa/mapProcThread+/tmp/proc_thread.txt%3Bmkfifo+/tmp/cecmdpipe%3Becho+socrates%3Doff+%3E/tmp/cecmdpipe%3Becho+resetfiles+%3E/tmp/cecmdpipe+%3Becho+socrates%3Don+%3E/tmp/cecmdpipe

Even when running out of IE web browser execute.html. Error in execute.pl

Need to RETRY running above in VMWare – Quick VMWare build gave same error

27

DevRocket (WinXP) – Remote Debug uImage (KGDB)

To prep for KGDB debugging on target, need to do on Host:make ARCH=arm CROSS_COMPILE=arm_v5t_le- menuconfig

•But this causes same build errors on WinXP due to:1. Kconfig “help” heading can’t take space (manually removed)2. Other build error with ?

•Workaround by running menuconfig in VMWare and copy .config to:/home/a0321791/montavista/devrocket2.0/workspace/uImageDevRocketLSP120

•In menuconfig got to add KGDB support target, and U-boot with:setenv bootargs mem=120M console=ttyS0,115200n8 root=/dev/hda1 rw noinitrd [email protected]/,@192.168.1.103/

But getting stuck in bootup with WinXP uImage with VMWare .config. Boots with VMWare uImage:kgdboe: local port 6443kgdboe: local IP 192.168.1.102kgdboe: interface eth0kgdboe: remote port 6442kgdboe: remote IP 192.168.1.100

uImage AIC33 (sample rate) Driver Manipulation

AIC33 driver divides fake speech.c sampleRate value to normalize. Printf works in decode app but not driver

DSP Side:

•Sample rate speedup x4 and slowdown /4

30



•Gave up on AAC decode due to CE error and lack of source.•Moved to all.x64p since source is available for codec and server (Built in Devrocket)

•ARM Side Object and Source:C:\mvcyg4.0\home\a0321791\montavista\devrocket2.0\workspace\allcopy\demos\decode\debug\decodedC:\mvcyg4.0\home\a0321791\montavista\devrocket2.0\workspace\allcopy\demos\decode\main.c

•Fake all.pjt (and allarm.pjt, though target GDB works better for ARM) project give at least function level debugging without –g option (adding C compiler options look like a RTSC-layer nightmare, though after figuring out linker LD_Flags options, need to revisit )

•For debug on ARM CCS can: File->Load Symbols->Load Symbols of decode. Then File->Load Symbols->Add Symbols only of dsplinkk.ko and cmemk.ko. But GDB works better (will show screenshot later)•For debug on DSP CCS: File->Load Symbols->Load Symbols of all.x64P. (will show screenshot later)

•Had to find/install framework_components_1_10_01 to build ??

CCS Interaction – Build in DevRocket, Debug in CCS…

CCS Interaction – Build in DevRocket•Gave up on AAC decode due to CE error and lack of source.•Moved to all.x64p since source is available for codec and server (Built in Devrocket)

•Used sphenc_copy to capture some audio content: ./encoded2 -s sin.raw.g711 -l -t 30•Used sphdec_copy play it:./decoded2 -l -s sin.raw.g711 nogdb dspoff

32



Due to codec engine errors with AAC decode, moved to all.x64p that copies a speech file. Used sphdec_copy to playback some audio content:./decoded2 -l -s sin.raw.g711 nogdb dspoff

Putting it in CCS gives the above with KOV, memory, and some C source/function level debug

ARM Side Make a .map file (Finally!). Not great for addresses due to MMU, but good to trace symbols and build sources. Look in:C:\mvcyg4.0\home\a0321791\montavista\devrocket2.0\workspace\allcopy\demos\decode\Makefile

And add –Wl, -Map option to LD_Flags#jg 10/23/08 Made ARM .map file LD_FLAGS += -lfreetype -lpng -ljpeg -lpthreadLD_FLAGS += -lfreetype -lpng -ljpeg -lpthread -Wl,-Map,allcopy.map

DSPLINK Interaction (CCS Only)

ARM and DSP talking over DSPLINK but breakpoints not stable on ARM with XDS due to ARM MMU. Can halt/run but no breakpoints, program memory manipulation
