| 11 arm64_download - this script downloads the Linaro's ARMv8 Aarch64 | |
| 12 toolchain and minimal embedded Linux system as well as ARM's | |
| 13 foundation model. The required files are mirrored on Google Cloud. | |
| 14 | |
| 15 If the files are already located in the working directory, the | |
| 16 download can be skipped if the checksums match. | |
| 17 | |
| 18 The script then starts a emulated Arm64 Linux system in the | |
| 19 background. After the boot is complete, you can SSH into the system | |
| 20 at port 8022 via user@localhost. The SSH key will be downloaded into | |
| 21 the working directery as well. | |
| 22 | |
| 23 Requires gsutil, xz, tar, and gunzip. | |
