-## AX650X Pyramid quick start
-
-The `ax650x-pyramid` machine directly boots Linux on the M5Stack AI Pyramid /
-AXERA AX650X platform. Detailed machine documentation is available in
-[docs/system/arm/ax650x-pyramid.rst](docs/system/arm/ax650x-pyramid.rst).
-
-### Boot Ubuntu 22.04 from eMMC
-
-The Ubuntu image has no MBR or GPT. Linux creates its twelve partitions from
-the fixed `blkdevparts` command line. The command below uses `snapshot=on`, so
-guest writes are discarded when QEMU exits.
-
-```sh
-QEMU=${QEMU:-build/qemu-system-aarch64}
-ASSET_DIR=${ASSET_DIR:-assets/ax650x}
-KERNEL=${KERNEL:-$ASSET_DIR/Image-5.15.73-axera}
-EMMC=${EMMC:-$ASSET_DIR/ax650x-ubuntu-22.04-emmc.raw}
-

-PARTS="$PARTS,1M(recovery_dtb),74M(recovery),30380032K(rootfs)"
-CMDLINE='console=ttyS0,115200n8 earlycon=uart8250,mmio32,0x2016000'

-    -serial chardev:serial0 \
-    -display none \
-    -monitor none \
-    -no-reboot
-```
-
-Override `QEMU`, `KERNEL`, or `EMMC` in the environment when the artifacts
-live elsewhere. Remove `snapshot=on` only when persistent image writes are
-intentional.
-
-### Run the Ubuntu quick-boot functional test
-
-The functional test uses the same direct-boot contract but lets the test
-harness own the serial chardev. It is in the `thorough` suite because the
-kernel and compressed eMMC image are downloaded assets.
-
-```sh
-meson test -C build \
-    --suite thorough \
-    func-aarch64-ax650x_ubuntu \
-    --print-errorlogs
-```
-
-The pinned kernel and qcow2 image are published at:
-
-<https://github.com/processmission/qemu/releases/tag/ax650x-ubuntu-22.04-qemu1>
-
-The harness verifies both SHA-256 digests. The test uses disposable eMMC
-writes and waits for DWMAC probe, partition 12, the mounted ext4 root
-filesystem, Ubuntu readiness markers, and the serial login prompt.
