| DESCRIPTION :
|
||||
|
|
||||
| Utility to convert a Linux Boot Image to S-record:
|
||||
| ==================================================
|
||||
|
|
||||
| This command line utility can be used to convert a Linux boot image
|
||||
| (zimage.initrd) to S-Record format used for flash programming.
|
||||
| This conversion takes care of the special sections "IMAGE" and INITRD".
|
||||
|
|
||||
| img2srec [-o offset] image > image.srec
|
||||
|
|
||||
|
|
||||
| Build the utility:
|
||||
| ==================
|
||||
|
|
||||
| To build the utility use GCC as follows:
|
||||
|
|
||||
| gcc img2srec.c -o img2srec
|
