Hello! When I run the FreeRTOS riscv-spike with -p2 (2 processors) i get the following error:

How can I succeed a multi-core simulation using Spike??

Thanks, Best regards.

Thank you for bringing this up. If my understanding is correct, this is a single hart port, so the multi-core spike will not work.

That's Correct Anton.
The intention was to demonstrate the 64bit FreeRTOS on Spike and it did not meant to be multicore RTOS port. Will update readme to make it clear so there is no ambiguity.

@noureddine-as , To succeed with running FreeRTOS on multiple cores you will need the FreeRTOS version which is capable of running on multiple Cores. You may find this discussion useful here

Thank you.

Hello, Exactly @AntonKrug . Thanks @nitindeshpande , I found that master thesis report months ago, but unfortunately, I didn't had time to implement the multi-core version, I just used the following repo https://github.com/illustris/FreeRTOS-RISCV which was a little bit more maintained.

Thanks!
