AWR1642BOOST: SRR Chirp參數調整

是否是因为frame里空闲时间太少导致数据来不及发送？能否加大frame period，看是否有改善？

你好，
我把PROFILE_SRR_IDLE_TIME_VAL及CHIRP_SRR_1_IDLE_TIME_VAL兩個參數，分別加大至1000U及2180U，但依然沒有改善。

请看一下下面的帖子，可能是RAM size不够。

你好，
針對RAM不夠的問題，先前我有進行測試，當Chirp設定在320時，會有RAM不夠的問題，在程式運行時會出現錯誤碼。因此後來我才修正chirp至300並運行程式碼，並無出現任何錯誤碼。

我使用的版本是mmwave_automotive_toolbox_3_0_0

请看下面工程师的回复。

I would like you to confirm the following:

• Was the application running fine before the modifications?
• Is the reload configuration box is checked in the GUI? This needs to be applied before starting the GUI.
• When you made the changes, were the changes applied to both the mss and dss project cfg header file?
• Can you confirm this is the same error you see in CCS when you try running the code with the changes?

Error: mmWave Config failed [Error code: -3108 Subsystem: 41]

If so, you will have to make changes either to the sampling rate or the ramp end time to accommodate the 300 samples for the same chirp.

Additionally, I would kindly request the customer to migrate to the latest version of the automotive toolbox if possible.

Hi Shine:

  針對幾點疑問回覆如下

• Was the application running fine before the modifications?  在未修改參數前，程式運作正常，GUI亦顯示正常
• Is the reload configuration box is checked in the GUI? This needs to be applied before starting the GUI. 針對GUI配置的部份，我不清楚當調整chirp數量後有哪個地方需要做相對應的修改，能否說明?
• When you made the changes, were the changes applied to both the mss and dss project cfg header file? 已有同時針對srr_config_chirp_design_SRR80.h內配置的參數做修改
• Can you confirm this is the same error you see in CCS when you try running the code with the changes? 當修改參數配置再重新運作時未出現錯誤碼，如下圖，但GUI未顯示偵測到的物體(請注意SAMPLERATE_VAL我已經調整至6,000, 且frequency slope設置為5.8，當SAMPLERATE_VAL設置在5000時的確會出現error)
