SMP demo fail, what can i do? #45

Closed zhangyang-hxd closed 2 years ago

zhangyang-hxd commented 2 years ago

I create a smp demo by "SMP Helloworld in baremetal environment @app-nsdk_smphello" on NucleiDemo. But it can't run into main() when i debug it with qemu, does i need to do any other configuration? I also build it from nuclei-sdk/application/baremetal/smphello by hand. Only one cpu run. LOGS:

Nuclei SDK Build Time: Jun 15 2022, 18:01:00
Download Mode: ILM
CPU Frequency 46858 Hz
Hello world from hart 0
Some harts boot failed, only 1/2 booted!

I think nuclei-n307fd which demo use by default does not support smp?

I test by below:

qemu-system-riscv32.exe  -machine nuclei_n -cpu nuclei-n307fd -smp 2 -serial stdio -nodefaults -S -s
qemu-system-riscv32.exe: Invalid SMP CPUs 2. The max CPUs supported by machine 'nuclei_n' is 1

Qemu not supported in 2022.04 release version, we will add this smp feature in qemu in future releases.

Same as the Nuclei Studio, SMP for qemu plugin need to be updated in future.

Ok, thanks。 So， if i want to test smp feature, i need to verify it on SOC, right? Which SOC i can use, UX900?

fanghuaqi commented 2 years ago

Yes, you need to contact our sales or AE to for support on UX900-MC, if you have our UX900-MC core, you can test it on fpga.

Check link here for how to run: https://doc.nucleisys.com/nuclei_sdk/design/app.html#smphello
