Working from scratch, I created a LabVIEW FPGA project that imports a MicroBlaze design that communicates with LabVIEW via a UART, and has the ability to change the elf file in a much shorter time frame than before. I did this by adding the MicroBlaze to the project after it had been exported to Vivado, … Read more
Before I go any further and start wiring up my code to use the lwIP on the embedded MicroBlaze, I will need some sort of better method of debugging. All code that I have implemented that uses a MicroBlaze processor via the Xilinx tools makes use of the UART to send and receive standard input … Read more
I normally avoid shop words or “corporate speak” because I feel it dehumanizes us, but sometimes these phrases are necessary. So here is the “30,000 foot” view. And please pardon the appearance of my flow charts and diagrams, I am not a graphic designer… All images open in a new tab, so just click on … Read more
The 10 Gigabit MAC/transceiver gives me 64 bit data words. I currently think I am giving and getting 64 bit data words, but I am really only using 32 bits. I came to this conclusion after I tried reading a 64 bit word and saw the data was simply two repeated 32 bit words. Additionally … Read more
I just uploaded some code to GitHub that is a full demonstration on how to use LabVIEW FPGA 2017, the MicroBlaze MCS core and the IO Bus that is attached to the MicroBlaze MCS. Clone the following repository: https://github.com/JohnStratoudakis/LabVIEW_Fpga/tree/master/05_MicroBlaze_Mcs/02_MicroBlaze_Mcs_IO_Bus and open the LabVIEW project: https://github.com/JohnStratoudakis/LabVIEW_Fpga/blob/master/05_MicroBlaze_Mcs/02_MicroBlaze_Mcs_IO_Bus/02_MicroBlaze_Mcs_IO_Bus.lvproj Look at the Vivado 2015.4 project: https://github.com/JohnStratoudakis/LabVIEW_Fpga/blob/master/05_MicroBlaze_Mcs/02_MicroBlaze_Mcs_IO_Bus/MicroBlaze_Mcs_IO_Bus/MicroBlaze_Mcs_IO_Bus.xpr And finally, using … Read more
