WebIIO triggered buffer depends on IIO buffer which is missing from Kconfig file. This should go unnoticed most of the time because there's a chance something else has already enabled buffers.

WebThe buffer-dma code was using two queues, incoming and outgoing, to manage the state of the blocks in use. While this totally works, it adds some complexity to the code, especially since the code only manages 2 blocks. easier to just check each block's state manually, and keep a counter for the next block to dequeue. WebThe AXI4-Stream IIO Read (HOST) block reads data from the direct-memory-access (DMA) buffer of the specified AXI4-Stream IP core device on a connected Xilinx ® SoC device to a running Simulink ® model.
