#QEMU SYSTEM ARM INSTALL#
Install QEMU and the EFI image for QEMU: $ sudo apt-get install qemu-system-arm qemu-efi.Note: this requires Ubuntu 15.04 or greater Getting the bits It is possible to boot directly into Linux instead. I've chosen to describe a UEFI-based system here so I can make use of the kernel on the guest's disk image. on an x86 host) or, accelerated w/ KVM if you have an arm64 host.
You can either do this fully emulated (e.g. For the projects created by the Eclipse Embedded CDT wizards, this is achieved by defining OS_USE_SEMIHOSTING outside Eclipse Embedded CDT it depends on the libraries used, for example newlib can be configured for semihosting by adding -specs=rdimon.specs to the linker options.Ubuntu/arm64 can run inside the QEMU emulator.
#QEMU SYSTEM ARM CODE#
When using QEMU for running unit tests, and expecting the exit code to reflect the test result, it is mandatory for the application to be compiled and linked as a fully semihosted application, in other words all system calls to be implemented using the semihosting interface. This is not really a big limitation, since unit tests can be configured to write an XML file with the detailed test results, so the binary exit code is enough to represent the pass/fail, and Continuous Integration systems will generally process the XML file for details.
#QEMU SYSTEM ARM FULL#
Unfortunately the semihosting specs do not allow to pass the full exit code, so for all other returned values, QEMU will return 1, which can be used as an indication of a failed test. This is particularly useful when running unit tests, since 0 means the test was successful. When started in semihosting mode, if the application’s main() routine returns 0 and the application is a fully semihosted one, QEMU will also return 0 to its parent process. The following options will be passed as argv … argv, without special processing. The first option will be passed as argv, so it generally should reflect the application name. There are many such options available, but the ones the plug-in uses are: To make QEMU inform the user about these problems, the -d options can be used to enable some debug options.
