I got an Arty A7 board coming to my desk, and I’m curious to try running a RISCV processor on it. Not long after following the tutorial from Digilent<\/a>, I was able to program the RISCV processor on this board just by using a MicroUSB cable.<\/p>\n\n\n\n Now I have a RISCV running on this Arty A7 Board. I need to run a program. After a couple of minutes of researching, I found this<\/a> post, I was able to put my program running by putting it on Or simply you could follow this explanation from YouTube<\/a> to try to run your program without a debugger.<\/p>\n\n\n\n Since I don’t have an Olimex debugger, I tried to find a way to debug it using J-link which is the only debugger available here. Luckily, I found this official guide<\/a> from Segger, I tried to connect all the pins and start my Freedom Studio<\/a>. I configured the debug configuration according to the wiki. Everything was going well until I found out that there is no output.<\/p>\n\n\n\n I thought it was a serial baud rate problem. Since the clock is downclocked and the serial baud rate is not updated. So currently in the master branch of freedom, the serial baud rate should be I wonder why my J-link does not succeed in programming the Arty. Is it because of the wrong pins? But J-link said it detects the RISCV. Then I realize at the log there is verify failure.<\/p>\n\n\n\n However, I cannot continue to troubleshoot since I have other works to do. If you guys know this problem please share it with me. I will update this post as soon as I got it working. \ud83d\ude09<\/p>\n","protected":false},"excerpt":{"rendered":" Running the RISCV Processor I got an Arty A7 board coming to my desk, and I’m curious to try running a RISCV processor on it.
