This is a known bug in release 18.1.0 of the Embedded Coder Support Package for ARM Cortex-A Processors. The following workaround is available until a bug-fix is released:
1. Delete the runQemu.p file:
<SUPPORT_PACKAGE_INSTALL_FOLDER>/toolbox/target/supportpackages/arm_cortex_a/+codertarget/+arm_cortex_a/runQemu.p
2. Open the MATLAB file:
<SUPPORT_PACKAGE_INSTALL_FOLDER>/toolbox/target/supportpackages/arm_cortex_a/+codertarget/+arm_cortex_a/runQemu.m
3. In line 61~62 of file runQemu.m, the variable zImage and rootfsImage assignments should be changed as below:
zImage = fullfile(busyboxLocation,'armcortexa9_busybox', 'zImage');
rootfsImage = fullfile(busyboxLocation ,'armcortexa9_busybox', 'rootfs.img.gz');
4. Deploy the edited MATLAB file into a P file.
