+# flash to eMMC
+
+Get binaries from https://drive.google.com/drive/folders/1UQHHIu6MnOFvrqAhE5PR-fHMnH8RyAf6 / openwrt-spacemit-k1-nas-MUSE-N1-ext4-pack.zip (for other vendor binaries, see also https://docs.banana-pi.org/en/BPI-F3/BananaPi_BPI-F3 )
+
+```
+unzip openwrt-spacemit-k1-nas-MUSE-N1-ext4-pack.zip factory/FSBL.bin u-boot.itb factory/bootinfo_sd.bin
+```
+
+and use the following partition_oreboot.json:
+```JSON
+{
+    "version": "1.0",
+    "format": "gpt",
+    "partitions": [
+        {
+            "name": "bootinfo",
+            "hidden": true,
+            "offset": "0K",
+            "size": "512",
+            "image": "factory/bootinfo_sd.bin",
+            "holes": "{\"(80;512)\"}"
+        },
+        {
+            "name": "fsbl",
+            "hidden": false,
+            "offset": "128K",
+            "size": "256K",
+            "image": "../u-boot/oreboot.bin"
+        }
+    ]
+}
+```
+
+then flash the whole thing (yes, bootinfo_sd.bin is fine even though we flash to eMMC; it's weird):
+
+```
+fastboot stage factory/FSBL.bin
+fastboot continue
+sleep 2
+fastboot stage u-boot.itb
+fastboot continue
+sleep 5
+
+fastboot flash gpt partition_oreboot.json
+fastboot flash bootinfo factory/bootinfo_sd.bin
+fastboot flash fsbl ../u-boot/oreboot.bin
+```
+
+NOTE: The above may not work with a fresh board. I initially used spacemit-flashserver --debug -part partition_oreboot.json with a modified fastboot.yaml:
+
+```yaml

+      set: 'version'
+      skip_fail: true
+      timeout:
