# Preparation
|
|
1. Decide which image you want to flash to the cm4. All images can be found on the [google drive](https://drive.google.com/drive/folders/1SCE0VCfHIKdJlZBVMUI5AOd8uqdrAA_7) and usually you can find an overview on the [CM4 Images Overview sheet](https://docs.google.com/spreadsheets/d/1hWfCUwhnYKjQz526QUwpVui-eFWYgPfyoRJ40pwvJD8/edit#gid=0). For this example I chose the image `cm16_240104.img.xz`.

|
2. Decide which physical cm4 board you want to flash the image to. A list of all cm4's that we own can be found in the [CM4 overview sheet](https://docs.google.com/spreadsheets/d/18PtsqKYUrfK0cAAFBfwtgTSo0JnJ0n5Dc3oIjpWry6I/edit#gid=0). For this example we chose the cm4 with ID 14.
|
|
1. Be aware that there are two versions of cm4s. The lite version requires a SD-card whereas the EMMC version does not. The flashing instructions are different for the two.
|
|
2. The cm4s also come with different RAM and EMMC storage. You can visually inspect the part numbers if you are unsure. E.g. [RAM](https://semiconductor.samsung.com/dram/lpddr/lpddr4/k4f6e304hb-mgcj/), or [EMMC](https://semiconductor.samsung.com/estorage/emmc/emmc-5-1/klmbg2jetd-b041/).

# Flashing

If you have the EMMC version follow the instructions here: https://onesecinc.atlassian.net/wiki/spaces/MC1/pages/35029029/Flash+CM4+EMMC+with+a+new+Image

If you flash a Lite version, plug the SD-card into your development computer and then follow the instructions starting from point 5.
