MMWCAS-DSP-EVM: how to generate mmwcas-dsp-evm image file for cascade radar real time application?

Other Parts Discussed in Thread: MMWCAS-RF-EVM

Hi,

I try to understand the working procedure of mmwcas-dsp-evm + mmwcas-rf-evm.

I have these boards, and please help me for several questions :

1. I use the prebuilt binary file for window: sdimage.bin.bz2, from the readme.txt I only copy this to SD card and restart the dsp-EVM, and run a matlab script as decribed in the document of Processor SDK radar user guide v3.7

Once the usecase is running, on the PC connected to the network router open Matlab and change directory to vision_sdk\apps\src\rtos\radar\src\usecases\cascade_radar_beam_form
Run the following matlab script:
radar_cascade_bf_demo(tgt_ip_addr, host_ip_addr, host_mac_address, platform, range_depth, profileNum);

I can compile the program without problem after this step

"5. On a successful build completion, the executables will be generated in the below path
/vision_sdk/binaries/apps/$(MAKECONFIG)/vision_sdk/bin/tda3xx-evm"

I got several files .xearp32F and .map ,.xem4, .rprc

I did the steps in vision SDK TDA2XX user guide v3.7

3.6.3 Steps to generate MLO

3.6.4 Steps to generate appImage

after running these two steps, I can get opp_high opp_low opp_nom opp_od folders and related data.

Question: how can I generate this image file sdimage.bin.bz2?

the sdimage.bin.bz2 data is about 234MB.

the AppImage and MLO files are very small compared to the prebuilt image sdimage.bin.bz2 file.

sdimage.bin.bz2 doesn't have the same content as AppImage and MLO.

sdimage.bin.bz2 is the linux u-boot/kernel and filesystem for cascade radar data capture.

AppImage and MLO is for TI-RTOS real-time processing.

Stanley, thanks for your info.

if we use SD card for boot, is it correct that only AppImage and MLO are copied into the SD card?

I havenot found the clear explanation in the document.

Could you just explain the main procedure, how to run the real time cascade application, by using which compiled codes?

thanks,

Kang

Please refer 3.5 Load using SD card in VisionSDK_UserGuide_TDA2xx.pdf.

You can find it under ~\vision_sdk\docs\UserGuides.

I found this part.

I just make sure, whether I get it correctly.

the SD card is first formatted by either option 1 or 2. -> this step means that the sd card is empty.

copy the AppImage and MLO at the root folder of the formatted SD card, -> means that only several files in the SD card, but there is no bootable OS.

This step differs from the prebuilt sdimage.bin.bz2 for windows? how are the AppImage and MLO called and executed? Maybe there are two OS systems TI RTOS and Linux? I am confused!

The compile data looks as follows, are they enough for running real time application?

Thanks for your patient.
