  Compile a textual representation of a BCT into a binary image.

- 2

  Generate an entire boot image from a previously compiled BCT and a bootloader binary.

### Platforms supported

- •

  **Tegra20**

- •

  **Tegra30**

- •

  **Tegra114**

- •

  **Tegra124**

- •

  **Tegra132**

- •

  **Tegra210**

## COMMANDS

- **-gbct**

- **-h, --help, -?**

  Print help text and exit.

## OPTIONS

- **-d, --debug**

- **-s, --ssoc *tegraNN***

  Select target device.  Must be one of: tegra20, tegra30, tegra114, tegra124, tegra32, tegra210.

- **-u --update**

  Copy input image data and update bct configs into new image file

## EXAMPLES

To generate a bct file from a text description obtained either through [bct\_dump(1)](/bct_dump/1.md) or cbootimage-configs:

```
$ cbootimage -gbct -t124 PM375_Hynix_2GB_H5TC4G63AFR_RDA_924MHz.bct.cfg PM375_Hynix_2GB_H5TC4G63AFR_RDA_924MHz.bct
New BCT file PM375_Hynix_2GB_H5TC4G63AFR_RDA_924MHz.bct has been successfully generated!
```

To generate a boot image file including the newly generated bct:

```
cbootimage -t124 jetson-tk1-emmc.img.cfg jetson-tk1-emmc.img
Image file jetson-tk1-emmc.img has been successfully generated!
```

## RETURN VALUE

If any error occurs a non zero exit status is returned.
