JNI error

[nachiket]

I'm sure its something buggy in my setup, but I get this error:

[info] ../verilator/VVexiiRiscv__spinalWrapper.cpp:5:10: fatal error: jni.h: No such file or directory
[info]  #include <jni.h>

I do have a JDK installed, but do I need a specific version? or any other missing packages beyond the JDK?

[Dolu1990]

JDK should be enough
Maybe some platform / version issue
What JDK do you have installed ?
Are you on windows / linux / ... ?

[nachiket]

java -version
openjdk version "11.0.19" 2023-04-18
OpenJDK Runtime Environment (build 11.0.19+7-post-Ubuntu-0ubuntu118.04.1)
OpenJDK 64-Bit Server VM (build 11.0.19+7-post-Ubuntu-0ubuntu118.04.1, mixed mode, sharing)

I'm on Ubuntu 18.04

I see a jni.h here
/usr/lib/jvm/java-8-openjdk-amd64/include/jni.h

[Dolu1990]

Ahh you have to get the version via javac --version

[nachiket]

javac -version
javac 1.8.0_362

I assume that's too old?

[Dolu1990]

hmm probably yes, i'm on

javac --version
javac 11.0.20.1

Ok upgrading the JDK fixed this issue.

But I'm now seeing a different error:

It mean that the CPU didn't commited anything since too long
Did you loaded some elf/bin ? if not that's normal

[nachiket]

I’m just running the command from the guide

https://spinalhdl.github.io/VexiiRiscv-RTD/master/VexiiRiscv/HowToUse/index.html

vexiiriscv.tester.TestBench --load-elf ext/NaxSoftware/baremetal/dhrystone/build/rv32ima/dhrystone.elf --trace-all

[Dolu1990]

Ahhh right, mul/div aren't anymore included in the default configuration, you need to add :
--with-mul --with-div

Also, here is an example of additional arguements you can use to improve IPC :

--with-btb --with-gshare --with-ras --decoders 2 --lanes 2 --with-aligner-buffer --with-dispatcher-buffer --with-late-alu --regfile-async --allow-bypass-from 0 --div-radix 4
