I am using ADSP21489 processor I loaded the code in flash using the below command
cldp -proc ADSP-21489 -emu ICE-2000 -driver "C:\Analog Devices\ADSP-21489_EZKIT-Rel1.0.0\21489_EZ-Board\Examples\Device_Programmer\serial\21489_m25p16_dpia.dxe" -cmd prog -erase affected -format hex -file D:\Karthik\BDL_ACU_140519\BDL_ACU_140519\Debug\BDL_ACU_140519.ldr"
here the file name is D:\Karthik\BDL_ACU_140519\BDL_ACU_140519\Debug\BDL_ACU_140519 this is path of project.
Using the above command i loaded the hex file now I want to erase the Flash
Please assist me how to erase flash what is the process for erasing and how to check the flash is erased or not.
Hi Eswar,Regarding," how to erase flash what is the process for erasing"cldp -proc ADSP-21489 -emu ICE-2000 -driver "C:\Analog Devices\ADSP-21489_EZKIT-Rel1.0.0\21489_EZ-Board\Examples\Device_Programmer\serial\21489_m25p16_dpia.dxe" -cmd prog -erase affected -format hex -file D:\Karthik\BDL_ACU_140519\BDL_ACU_140519\Debug\BDL_ACU_140519.ldr"In order to erase the flash, you can use "erase all" instead of "erase affected" while loading the code. The "erase all" will erase the flash completely.Regarding," how to check the flash is erased or not."Can you please have a look at the example available in the ADSP-21489 Board support package(BSP) to check the DSP. Please download and install the board support package for ADSP-21489 in the below download.analog.com/.../ADI_ADSP-21489_EZKIT-Rel1.0.0.exeOnce you installed, you can find the example code in the below path.[Installation directory]:\Analog Devices\ADSP-21489_EZKIT-Rel1.0.0\21489_EZ-Board\Examples\Power_On_Self_Test\srcRegards,Lalitha.S
thanks for your reply but you have not mentioned clearly the command.
cldp -proc ADSP-21489 -emu ICE-2000 -driver "C:\Analog Devices\ADSP-21489_EZKIT-Rel1.0.0\21489_EZ-Board\Examples\Device_Programmer\serial\21489_m25p16_dpia.dxe" -cmd prog -erase all
this above command is enough to erase the flash or any thing is there.
please let me know what is the full command to erase.
Hi Eswar,Can you please confirm are you trying to erase the flash before loading your application? If yes, please use the below command to erase and load the application into the flash.cldp -proc ADSP-21489 -emu ICE-2000 -driver "C:\Analog Devices\ADSP-21489_EZKIT-Rel1.0.0\21489_EZ-Board\Examples\Device_Programmer\serial\21489_m25p16_dpia.dxe" -cmd prog -erase all -format hex -file "D:\Karthik\BDL_ACU_140519\BDL_ACU_140519\Debug\BDL_ACU_140519.ldr"Please let us know if there any queries on this.Regards,Lalitha.S
thanks for your reply.
But my problem when i am loading this command to processor it is telling below thing.
Here what i understood when it is trying to load it is unable to create .ldr file,how to overcome from this issue.
please assist me with any example to load the program with pictures or any document.
will you please tell me that .ldr file it will generate automatically or not.
Hi Eswar,Please note that you have to generate a loader file(.ldr) file for your application. Once the loader file is generated you can load the LDR. In order to program the flash, please refer the “Using Loader Files” section in the “readme.html” available in the ADSP-21489 board support package. You can download and install the BSP (Board support package) for ADSP-21489 in the below link.download.analog.com/.../ADI_ADSP-21489_EZKIT-Rel1.0.0.exeOnce you installed you can find the “readme.html” in the below mentioned path.[Installation directory]:\Analog Devices\ADSP-21489_EZKIT-Rel1.0.0\21489_EZ-Board\Examples\Power_On_Self_Test\readme.htmlFor your reference, we copied the below procedure mentioned in "readme.html".1) Create a loader (.LDR) file that can be programmed into a flash device. 1) Assuming your project is already loaded into CCES, go to the "Project" menu and choose "Properties", then "C/C++ Build", then "Settings", then "Build Artifact" tab. 2) There you will see "Artifact Type". From the dropdown menu select "Loader File". 3) Click on the "Tool Settings" tab and select "CrossCore SHARC Loader" then "General". 4) For "Boot mode" choose "SPI flash" for serial or "Prom" for parallel. 5) For "Boot format" choose "Intel hex". 6) For "Output width" choose "8-bits". 7) "Prom start address" should be blank. 8) "No kernel" should be unchecked. 9) "Use default kernel" should be checked. 10) Click "OK". 11) Rebuild the project to generate the LDR file. 2) Download the LDR file into flash using the Command Line Device Programmer (CLDP) application.>> Please refer to the CLDP help for more information. Note, there are many options when using the CLDP (including defining your connection type, driver file, loader file, etc. Here is a sample command line to program the POST loader file to the parallel flash on the EZ-Board using an HPUSB-ICE emulator:cldp -proc ADSP-21489 -emu hpusb -driver "C:\21489_EZ-Board\Examples\Device_Programmer\parallel\21489_m29w320_dpia.dxe" -cmd prog -erase affected -format hex -file "C:\21489_EZ-Board\Examples\Power_On_Self_Test\Debug\21489_post.ldr"We also recommend to refer the "FAQ: How do I program flash on my target board using CrossCore Embedded Studio" which might be helpful.ez.analog.com/.../faq-how-do-i-program-flash-on-my-target-board-using-crosscore-embedded-studioHope this helps!Regards,Lalitha.S
