The HW Refeference Manual tells about a DMA Error IRQ:
"The DMA channel has two interrupt signals for support of a number of events such as work-unit state events, peripheral
interrupt request (PIRQ) events, peripheral data request (PDR) events, and DMA channel errors. The channel
reports DMA channel errors on a dedicated interrupt signal."
and
"All the DMA error interrupts are combined into a single shared interrupt. Combined error signals require reading
the DMA_STAT register of each DMA channel associated with a combined error interrupt to determine the DMA
channel responsible for the generation of the interrupt."
Which Interrupt ID has this error interrupt? In the SEC interrupt list there is not such "DMA Error Interrupt". If there is no dedicated interrupt ID for the DMA errors how to do they trigger an interrupt?
Hi Julian,
The interrupt ID for DMA error is 26(SYS_DMAC_ERR). It is available in the HRM under "Table 8-2: ADSP-BF70x Interrupt List"(Page No: 266/2223).
