Arty E300 flow broken #32

Closed kenzhang82 closed 7 years ago

kenzhang82 commented 7 years ago

Hi,

I noticed that the repo has been updated recently and a pull request is accepted, and the flow of generating mcs for Arty board is broken.

What I did:

git clone --recursive https://github.com/sifive/freedom.git cd freedom make -f Makefile.e300artydevkit verilog (as per README) - this generates verilog without error. make -f Makefile.e300artydevkit mcs (as per README) - this prompts an error below:

"

Is this intentional? How could I resolve this? Thanks.

You need to set the environment variable for $RISCV which points to the location where your local version of the RISC-V toolchain is installed to compile the bootloaders. The README has been updated to reflect the same.

Thanks. It works now.

Sorry for opening this issue again, I got another error when I try to generate the mcs file as per README:

" File "/projects/freedom0821/freedom/rocket-chip/scripts/vlsi_rom_gen", line 114 for key, val in iterate_by_n(line.split(), 2)} ^ SyntaxError: invalid syntax make1: /projects/digital/work/ken/freedom0821/freedom/builds/e300artydevkit/rom.v Error 1 make1: Leaving directory `/projects/freedom0821/freedom/bootrom/xip' make: /projects/freedom0821/freedom/builds/e300artydevkit/sifive.freedom.everywhere.e300artydevkit.E300ArtyDevKitConfig.rom.v Error 2 "

Did I miss anything (package, library etc)? Thanks.

What python version are you using? I just tested this on Python 2.7.12.

>> python --version
Python 2.7.12

Aha, that solves the problem. Thanks.
