The system functions correctly when I use an interrupt from RTD (IntCtrl_Ip_Init). However, for my project, I am using a different file to configure the interrupt handler, set priority, and enable the handler. For DMA0_CH1 &DMA0_CH16,i am using IRQ : DMATCD1_IRQn / Dma0_Ch1_IRQ...
Hi Brandon, I found a strange question. The DMA driver can work well without this statement:system("Any instruction") in C language source code.Here's what I did. axidma_init(); axidma_malloc(); axidma_oneway_transfer(); axidma_oneway_tr...

Users of the functions are updated accordingly. This is only an interface change. It is currently expected that dma-buf memory can be accessed with system memory load/store operations. v3: * update fastrpc driver (kernel test robot) v2: * always clear map parameter in dma_buf_vmap() (...
