Hi,
I am trying to use 1tx in the mmw demo (SDK5.3), and change the number of sampling points to 512 and the number of chirps to 64,
which means that the size of the RD Matrix will become 512/2*64*4 = 64K, I tried two configurations, the difference is that the value of ChirpTxMimoPatSel is different：
But in SDK5.3 The RD Matrix is limited to no more than 32K:
In CFAR_DET_HWA_config_HWA() and CFAR_DET_HWA_config_EDMA() fuction ：
I tried to change the limit to 64K, but the SNR values of the point cloud were completely wrong. Some were "+inf" and some were negative numbers.
And if I change the number of chirps to 32, this problem disappears.
Why does this problem occur? In the case of 1tx, the memory space is enough, so is the size of RD Matrix limited by HWA?
Thanks!
