[U-Boot] What file formats can be loaded and launched by u-boot

[Misbah]

Hello All,

 

I have an RTOS compiled for ARM cotex-A9 generating .out file format.

 

How can I use u-boot.bin to download the RTOS image from an SD card "FAT32
formatted" and launch the RTOS kernel

 

Can you please share your views.

 

Regards,

Misbah

".out" is not any known linker output format.  Do you mean a.out?  It
has been ages since I've seen this used the last time - way back in
the previous millenium.

In general, you can use objcopy (from the GNU binutils package) to
convert into raw binary format.  This you can then either load
directly, or wrap it using the mkimage tool into either a legacy
U-Boot image or a FIT image, which then can be started by U-Boot.

Best regards,

In the near future, the probability is close to zero. In the  distant
future, I'll be dead, and posterity can do whatever they like... :-)
