MCU-PLUS-SDK-AM273X: HWA paramset配置问题

Part Number:MCU-PLUS-SDK-AM273X

你好，专家

我在尝试配置am273x DDMA处理的dopplerprochwaDDMA中遇到了问题；描述如下：我想在sumTx后面加上一个doppler维度的CFAR，由于需要使用sumTx的输出作为输入，所以将原来完成sumTx后触发EDMA搬运sumTx结果的操作放到完成CFAR后进行。但是做出如上更改后，am273x在调用函数DPU_DopplerProcHWA_config进行配置时，就失败了。我在加上cfar的paramset后，已经调整了参数DOPPLERPROCHWA_DDMA_DOPPLER_NUM_HWA_PARAMSETS和obj->dopplerAzimHwaCommonConfig.paramStopIdx；请问是什么原因导致的上述问题。配置代码如下：

谢谢

Gary Lu：

您好，

1. 参数设置错误：您已经提到了调整了参数DOPPLERPROCHWA_DDMA_DOPPLER_NUM_HWA_PARAMSETS和obj->dopplerAzimHwaCommonConfig.paramStopIdx。请确保您对所有相关参数进行了正确的设置，包括CFAR的参数和相应的内存配置。检查这些参数是否正确设置。

2. 内存访问冲突：当您将原来的操作放到CFAR后时，可能会导致内存访问冲突。请确保您在进行CFAR操作时没有修改sumTx的输出内存。如果在CFAR操作过程中需要访问sumTx的输出，请确保使用正确的同步机制（例如互斥锁）来避免冲突。

3. 资源不足：添加CFAR操作后，可能会导致资源不足的问题。请确保您的系统有足够的资源（例如内存、计算能力等）来支持同时进行sumTx和CFAR操作。如果资源不足，您可能需要重新评估您的系统配置或优化您的算法。
