xilinx-vdma 40400000.dma: Channel dd6de610 has errors 100, cdr 1e051700 tdr 1e051780

I made modifications based on axidma_video_transfer and implemented a DMA SG transfer function, but now it's reporting an interrupt error: errors:100.

Current situation:

• With a single buffer, the DMA works well, correctly receiving data from the PL side and triggering callbacks.
• With multiple buffers, the DMA runs normally for a while but then reports an errors:100 error, after which the DMA stops working.

Why is this happening? Has anyone encountered a similar error before?

I just use DMA (not VDMA) but sometimes I got error below after a while:
xilinx-vdma 80200000.dma: Channel 00000000b50e4cbd has errors 10, cdr 0 tdr 0
I am struggling with this. Do you have an suggestion? Thanks very much!
