i'm running an hard to debug issue with Sigma Studio framework example firmware and CrossCore 2.9.4 on ADSP21569 eval board
After 2^32 samples are processed the output stop play sigma studio processed output but keep playing last "block size" samples ( 64 for in my case ).
At this point the output buffer continue playing that old data also if the other part of the firmware, input + sigma studio processing work fine.
Seem that copy from sigma studio outputs to SPORT output buffer is broken but i need help to understand what is happening in detail, i don't see any issue with DMA interrupt and stuff around the buffer copy.
Thank you in advance.
