MMWCAS-RF-EVM: MMWCAS-RF-EVM数据采集过程中存在丢帧问题

Part Number: MMWCAS-RF-EVM
Other Parts Discussed in Thread: AWR2243

TI工程师您好,我在使用2243级联板进行数据采集的过程中,总是存在丢帧问题。我的lua文件设置为采集100帧,最后实际只有70帧到80帧,请问这是为什么?

TI engineer Hello, I use 2243 expansion board for data acquisition process, there is always a frame loss problem. My lua file is set to capture 100 frames, but it only ends up at 70 to 80 frames. Why? 

  • 请参考mmwave_studio_cascade_user_guide.pdf里,下面第二条known issue

  • Hello, I have confirmed that more than one frame is missing. Where is num_frames_to_capture? We have not set this parameter to 0, so what is the problem of missing frames?

  • Where is num_frames_to_capture?

    在Cascade_Capture.lua中

    We have not set this parameter to 0, so what is the problem of missing frames?

    请问使用的是哪个lua? 除了设置100 frames,其他使用的都是默认值吗?帧周期是多少?

  • 其他都是默认值,帧周期是100ms

  • 不修改lua,全部用默认值会出现丢帧吗?另外,是怎么判断丢帧的?

  • 会丢帧,因为我设置的100帧,用脚本读取adc数据后只有81帧的数据

  • 使用的是Cascade_Capture.lua?用哪个脚本读的?

  • 对就是这个脚本,哪个脚本读的是什么意思,读取代码是根据示例写的,可以根据文件大小判断帧数不同

  • 你好,

    请问你是如何修改的?

    Thanks,

    Chris

        A. FRAMING & CAPTURE
        1. Triggering Slave (3, 2, 1) sequentially in a hardware triggered mode.
        2. Triggering Master in a software triggered mode.
    
        B. TRANSFERRING FILES
        1. The data is stored in file(s) with max cap placed at 2 GB.
        2. The files can be retrieved from the SSD (/mnt/ssd folder) using WinSCP.
    
    Note: Update lines 18 to 49 as needed before using this script.
    --
    
    Note: "capture_time"  is a timeout for this script alone to exit - it does not control the 
    actual duration of capture. The actual capture duration depends on the configured frame time 
    and number of frames.
    --]]
    
    capture_time                     =   2000                             -- ms
    inter_loop_time                  =   2000                             -- ms
    num_loops                        =   1
    
    --[[
    Note: Change the following three parameters as desired:
    1. n_files_allocation: is the number of files to preallocate on the SSD.
       This improves capture reliability by not having frame drops while switching files.
       The tradeoff is that each file is a fixed 2047 MB even if a smaller number of frames are captured.
       Pre-allocate as many files as needed based on (size_per_frame * number_of_frames) to be captured.
    2. data_packaging: select whether to use 16-bit ADC data as is, or drop 4 lsbits and save 4*12-bit numbers in a packed form
       This allows a higher frame rate to be achieved, at the expense of some post-processing to unpack the data later.
       (Matlab should still be able to unpack the data using the '*ubit12' argument to fread instead of 'uint16')
       The default is no-packing, for simplicity
    3. capture_directory: is the filename under which captures are stored on the SSD
       and is also the directory to which files will be transferred back to the host
       The captures are copied to the PostProc folder within mmWave Studio
    
       Note: If this script is called multiple times without changing the directory name, then all 
             captured files will be in the same directory with filename suffixes incremented automatically. 
             It may be hard to know which captured files correspond to which run of the script.
       Note: It is strongly recommended to change this directory name between captures.

  • 你好,

    我建议你增加帧周期时间,你怎么减少了?默认是100

    local Inter_Frame_Interval      =   75    -- ms

    我刚刚尝试了一下,默认的配置下仅仅做如下修改(100帧),采集的数据是99帧,每个AWR2243输出的数据量为256*4*12*64*99*4=311427072 bytes。如果pc上的master的数据大小不正确,请参考 mmwave_studio_cascade_user_guide.pdf里 8.1.2 Using WinSCP,登录DSP处理板上的Linux,查看mnt目录下的数据,应该都是正确的。

    local nframes_master = 100 -- Number of Frames for Master
    local nframes_slave = 100 -- Number of Frames for Slaves

    Thanks,

    Chris
