RE: Problems of buliding codec engine examples
Resend due to bounce. If you have purchased the DVEVM, then you can access all of the content with the exception of the c6x+ compiler from www.ti.com/dvevmupdates. From the message below, it looks like you have access to v1.10 - please be advised you should update to the u-boot provided with the 1.10.01 release as this fixes a problem where the DSP power is not properly enabled by u-boot in v1.10. You can purchase the DVSDK-L and get a full license to MontaVista Linux and access to the c6x+ compiler or you can purchase CCS 3.3 to get access to the c6x+ compiler.

Re: RE: Re: RE: Problems of buliding codec engine examples
Hello, George Thank you very much! I am confuse that why Wintech just use only 64MB DDR memory on the DVEVM board? As we know that the DDR memory isn't expensive at all now. As all the software pakages release withe the DVEVM are set to map the 256MB DDR, it will be very difficult for as to use the board with 64MB DDR memory! Thanks again and with my best wishes to you! Beny Zhang, It seems there is no simple way to change the memory map, because the DSP executable need a fix memory map, so when you changed your memory map you will rebuild all things related to DSP, such as dsp link, codec engine. you can following this link:http://www.mail-archive.com/davinci-linux-open-source@linux.davincidsp.com/msg01238.html Thanks George Gu (Xiangyu Gu) Wintech Digital System Co.

And now I have correctly build the examples of the codec engine. Before I run the examples I want to make clearly of this question: We know from TI that the DVEVM board should have 256MB DDR Memory, but the DVEVM board I boughth from Wintech(the dealer of TI in China) has only 64MB DDR Meomory on the board! Now, how can I set the memory map of the Davinci to run the exanples? Since the rules of setting the memory map is so complex in the build_instructions.html file. It is there any easy way to do this? Best Regards! Beny 1. If you _just_ want to rebuild the ARM-side examples, you can comment out C64P and Linux86 from the Build.targets array. What are these targets? * C64P == the DSP side of DaVinci target. It's one of TI's DSP processor families (http://focus.ti.com/dsp/docs/dspplatformscontenttp.tsp?sectionId=2familyId=132tabId=489). * MVArm9 == MontaVista Arm 9 target. This is the ARM side of DaVinci. * Linux86 == Intel's x86 target. A not-always-understood detail about Codec Engine is that it can run natively on x86 processors. This feature's got some limitations (codecs must be local, and must not access hardware since they run in user mode), but you can do a fair amount of development on this environment. 2 3. As you correctly supposed, BIOS is only needed if you're building DSP-side content (same with FC - Framework Components). You should set REQUIRE_BIOS = 0. BUT... Looks like you've identified a bug in xdcpaths.mak where it's always verifying your FC_INSTALL_DIR, even if you're only building for the ARM. Bummer. In your case, since you don't have (or need!) a valid FC installation, you can safely comment out the $(error ...) statement in xdcpaths.mak: --- ifeq ($(wildcard $(FC_INSTALL_DIR)/packages/ti/sdo/fc/dskt2/package.xdc),) #$(error FC_INSTALL_DIR is set to $(FC_INSTALL_DIR), which is invalid. Set this in codec engine examples/xdcpaths.mak! See the build documentation to correct this error.) endif --- As well as the assignment of MISC_PACKAGES to include $(FC_INSTALL_DIR)/packages at the very end: --- MISC_PACKAGES = $(XDAIS_INSTALL_DIR)/packages;$(DSPLINK_INSTALL_DIR)/packages;$(CMEM_INSTALL_DIR)/packages/;$(FC_INSTALL_DIR)/packages --- We'll fix this in a future CE release. Thanks for flagging this, and let me know if you have any other questions/issues.

When I try to build example codec and change the /dvevm_1_10/codec_engine_1_02/examples/codec dir and type gmake clean the shell tell me that the FC_INSTALL_DIR is wrong. So can I build the example codec running in the DVEVM board without building DSP-side content? How? And can I download the DSP/BIOS and FC from TI freely? Or I should pay for them?
