S32K344 DMA Channel to Channel linking

Hi, 

I am trying to make a DMA chain with 3 DMA channels and am trying to make DMA-channel linking to work. Essentially, I need DMA_CH0 to complete its major loop and start DMA_CH1. After DMA_CH1 finishes its major loop, start DMA_CH2. I am however having a lot of trouble getting this channel linking concept to work, where if I do a software request for DMA_CH0, only CH0 fires, but does not seem to request CH1. I even played around with RM CDD, but nothing seems to get me where I need to be....

Could someone be kind enough to look at my code to see what I am doing wrong?
