Hi, Has anyone else encountered this issue too? Currently, I am working with this flute core and also facing this same problem. If anyone can give me the reason for this issue or the solution, that would be great.

Hi, I have solved the issue. The problem is with the stride mentioned in the UART_MODEL.bsv file. The C program is written for the stride value 8. So, just change the stride value in the uart-model.bsv to 8. Then it will be fine. Bluespec team helped me to encounter this issue and thanks to the Bluespec
Hello
I'm trying to run the Flute hello world example, but I'm getting an error when the code tries to write to standard output.
I just built the latest bsc (commit ad02e93) with ghc 8.0.2, then checked out the latest Flute (commit c6f66da) and launched
make build_all
in the Examples/Eg040_Mergesort directory. I'm on Xubuntu 18.04 64bit.The build works, but when I try
make run_hello
I get the following output:In place of the Hello World string, I get the byte 0x1a in the terminal, followed by this error:
I tried previous commits of Flute (doing a
make clean
between versions) going as far back as August 2020 (commit 2465f93) when this tutorial was put together, but it didn't solve the issue.
