FAQ: Is it possible to generate an application LDR with schematic code and parameter embedded in it?

Q: Is it possible to generate target application LDR file with schematic 'code' and 'parameter' embedded in it?

---------------------------------------------------------------------------------------------------------------------------------------------

A: It is possible to create an application LDR file with schematic 'code' and 'parameter' embedded in it. Please refer to the attached document "SigmaStudio_No_Download_Mode.pdf" for more details.

Once this LDR file is booted on to the target, the schematic processing starts. There is no need to perform 'Link-Compile-Download' from the SigmaStudio host.

Alternately this LDR can be written to the target flash. This enables the user to boot the application from the flash and work without the USB to SPI conversion hardware.

* app.c inside ss4sharc_no_download.zip is based on SigmaStudio for SHARC 2.2.0

    The source file will get included automatically to project if you copy the file "ss_code_param.asm" to "\Target\Demo\ADSP-21489" folder, there is no issue with this procedure. The step which I shared will…

    Please follow the below steps to get parameter tuning control, 1. Once flashing done, modify the SW4 switch on the board from position ‘0’ to ‘1’. 2. Reset the board 3. Now connect the USBi to board…

    Hi Joseph I succeeded at the rebuilding of the project to generate the LDR file. 
    but the crosscore environment is showing errors because it does not know the two headers files "sport.h" and "backchannel.h",
    I use a card sharc 21489. Thank you in advance.

    Hi,

    The parameter tuning feature can work properly now by referring to your above instructions.

    Thanks for your enthusiastic response!

    Please follow the below steps to get parameter tuning control,

    1. Once flashing done, modify the SW4 switch on the board from position ‘0’ to ‘1’.

    2. Reset the board

    3. Now connect the USBi to board and open the same SigmaStudio schematic which you have used to generate code and parameter.

    4. do "Link compile connect" from SigmaStudio schematic. Refer attached image "Link_Compile_connect.png".

    The parameter tuning can be done when "Link Compile connect" success, Refer attached image for  "Ready:Compiled" status.

    Thanks,

    Sakthivel.P

    Hi,

    You are right. It's my carelessness! I forgot delete the file "ss_code_param.asm" that I put into the "...\Target\Demo\ADSP-21489" folder previously after following your steps. When  I delete it, the error disappears.

     

    Further, the application with schematic code and parameter embedded in it could run on the board when I write the generated LDR file into SPI flash and then the board is powered off and again powered on. At this time, no emulator or USBi are connected to the board. After that, I open the same SS4SH project in the SigmaStudio that are combined with  default application for sharc 21489 previously and connect the board to my PC with USBi. I try tuning module parameter of block shematic tab, there is no sound effect difference in different parameter settings. Parameter tuning seems doesn't work. What should I do to make parameter tuning ok?

     

    Thanks!
