Hi, after trying to understand a little bit deeper at the "arm_vmm.run" file in an effort to expand this to run 2 VMMs parallel, I faced some issues I do not understand well. So I hope to get here your expert help to clarify what I missundersand. 1.- Arm-Run-File: I modified the vmm_arm.run adding a 2nd component vm2 as you can see in the attached file. The result of this you can see in the attached result-file. So no entry point is found for this 2nd component. 2.- Source, wandering through the source structure /repos/os/src/ I found the "terminal_expect_send" in the test directory. What do i expect to find in the os-test-directory structure? Greetings, Peter
