The hardware has already been compiled for your convenience, if you wish to recompile the hardware then you must regenerate the system in SOPC Builder. Navigate altera sgdma the following location using the Nios II command shell:. Home Community More.

The problem is altera sgdma this dma design doesn't work. The data I get is corrupted. I've tried to disconnect altera sgdma. Obviously when it is connected to DDR ram it works, but when to onchip ram it doesn't. Follow Share. Available from ISR: Yes.
Returns: Returns 0 success. Other return codes are defined in errno. Storing the descriptor list in an external memory frees up resources in the FPGA; however, an external descriptor list increases the overhead involved when the descriptor processor reads and updates the list. The SG-DMA core has an internal FIFO to store descriptors read from memory, which allows the core to perform descriptor read, execute, and write back operations in parallel, hiding the descriptor access and processing overhead. The descriptors altera sgdma be initialized and aligned on a bit boundary.
How to Altera sgdma the Transmission Zero" and a link to a video design should appear in the results. Too bad there are no examples on simple SGDMA : That descriptor allocation and set up stuff is quite hard to understand and fulfill. Great job! I think I will have to dig the INiche source or other already written source, since it is really hard to understand how to make it run from a scratch. The easiest way would be to have a second descriptor chain ready to go so that when the interrupt fires from the completion of the first chain you can quickly write the start of the altera sgdma chain.

Unfortunately this means you will have a little bit of dead time between the chains. Returns: Returns 0 success. Other return codes are defined in errno. Description: Set up and begin a non-blocking transfer of one or more descriptors or a descriptor chain. However, I noticed that, in a rather random pattern, the system will just get stuck on the while loop waiting for the Altera sgdma to be empty. For more complete information about compiler optimizations, see our Altera sgdma Notice. This gives the possibility to build transfer queues which the DMA controller transferes after each other.

However, I noticed that, in a rather random pattern, the system will just get stuck on the while loop waiting for the FIFO to be empty. The code in between each time I call the write master is about 0.Since the core consists of multiple cores, you can replace any core without redesigning the entire SGDMA. This design example moves multiple. This user guide describes the embedded peripherals IP cores that work seamlessly with altera sgdma Nios II processor.
