“$ make -f Makefile.e300artydevkit verilog” error about freedom

Have you tried increasing the size of the perm gen space using extra command line flags to the JVM?

You may want to replace this line of the Makefile with:

SBT ?= java -XX:MaxPermSize=256M -jar $(rocketchip_dir)/sbt-launch.jar

Also, apparently Java 8 removed permanent generation, so you will never run out of PermGen space on Java 8.

@richardxia Thanks Richard,

Both add your code in common.mk and replace java7 with java 8 all work, but another question show again!

It seems that you must be using a very old version of Scala that isn't properly parsing build.sbt. Apparently, three years ago, you needed to put blank lines between each line. Can you try upgrading Scala to 2.11.7 to match rocket-chip (but definitely not to 2.12)?

Hi,

my scala version is 2.11.7,so met that question! where can download old version of scala?

[richardxia]

I think that shows the version of Scala sbt will use to compile the project, but I don't think that is the version of Scala that is used to read in the sbt project files. Perhaps you could try installing Scala manually from the official website? https://www.scala-lang.org/download/2.11.7.html
