This program is used to create images suitable to place into the boot flash of a device using a Tegra SoC. There are two primary modes of operation of cbootimage:
1 |
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. |

−u −−update
Copy input image data and update bct configs into new image file
To generate a bct file from a text description obtained either through bct_dump(1) 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!
If any error occurs a non zero exit status is returned.
