Since I don't have these boards yet, I'm emulating it with qemu. The practice in turn consists of launching with qemu a very small operating system with two tasks that make a series of system calls. - -When I run this practice on my host it works correctly, but when I run it on an Ubuntu emulated in riscv with qemu, the cause code for the trap changes (the first bit of the code). - -The demo can be found in this repository: https://github.com/Sft570/qemu-bug-report -Steps to reproduce: -1. Clone the repository on the host and run the demo with "make qemu" -2. Emulate with qemu ubuntu in riscv, clone the repository and run the demo with "make qemu". - -The error displayed shows the change of the cause code bit. You can analyze its behavior in the trap.c file in the src folder. -Additional information: - |
