Hello people, I am used to using U-boot in order to boot Linux, but now I also need to boot VxWorks.
Till now I copied the Linux kernel in Flash and when I wanted to update it, I had two options: doing it from U-Boot (tftp the image and using the cp command) or from Linux (using the dd command or flashcp). The kernel is always in the same flash location, a determined address. So I have to reserve enough memory in case the updating is bigger. With VxWorks, I works as follows: the bootloader mounts a filesystem in flash where I can transfer through ftp the operating system, VxWorks. I mean, I can see the operating system as a file. In Linux I don't have it, but the operating system image is saved in flash from an address. I am not sure if people who use VxWorks works like me or there are other options to boot. The good with my option is that you can update the operating system just changing the file with ftp. The thing is I would like to use the same U-Boot to boot both systems: Linux and VxWorks. So I should have to have a similar way to boot. The only difference will be the boot command: bootvx for VxWorks and bootm for Linux. Could you explain me what the common way to use U-Boot with VxWorks is? I doubt a lot what is the best option: - Tring to mount a filesystem with U-Boot that VxWorks also understands. - Making like with Linux. I mean, copying the VxWorks from an determined address. Then the VxWorks won't be seen as a file. - Others not thought yet.... Is there documentation about VxWorks with U-Boot? I would thank you your help!
