You could add a new type for your binary.

Re: [U-Boot] Booting a proprietary OS
Hi! Yes, i have a question about U-Boot. Can i use U-Boot as bootloader for a proprietary operating system? I want use bootm command and a bin file. In particular the Image kernel is produced by mkimage command with following option: - standalone - uncompressed - arm architecture - U-Boot application - with a specified load address and entry point Then i load Image file from SD-card with ext2load command and i start it with bootm command. Can it be a good idea and solution? Do you have any suggest?

[U-Boot] Booting a proprietary OS
Hello everybody!!! I need to port an operating system from x86 architecture to ARM architecture. In particular i'm using a Cubietruck board board with Cortex A-7 CPU. Initially i would use U-boot as bootloader for my operating system: so i concentrate on kernel porting! If i use mkimage command to create the image uncompressed of my operating system should i project some decompressing operation for the kernel or not? I explain batter: after loading from SD-card the kernel image and executing bootm command to start the kernel. at the entry point of the kernel what operation should i do and implement?? It's very important Thanks in advance -- View this message in context: http://u-boot.10912.n7.nabble.com/Booting-a-proprietary-OS-tp270884.html Sent from the U-Boot mailing list archive at Nabble.com. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
