A simple dma design is in use. Adding two dma stream input(dma_in1, dma_in2) and stream output(dma_out). Add is by HLS IP.
disable scatter gather engine and all the other settings as default
enable axi HP0 slave port
What I want do is just add/sub for partial reconfiguration.
Before downloading partial bitstream , I used API channel.idle and found dma is not in idle, but still continue to download add partial bitstream and error message pop out
The program stuck on dma_out channel.
By the way, if i just use add hlsip to perform add function in full configuration, it worked.
Thanks for everyone’s help.
