Easily upload large images via u-boot?

Tue Feb 17, 2015 10:44 am

Hi all,

I have adopted a rather silly process for uploading my large (7.1M) images:
    - u-boot
    - use tftpboot to install the original VoCore firmware
    - wait
    - scp my new image to the VoCore
    - sysupgrade <new image>

I'm doing this because u-boot really doesn't want to know about my large image file, and (for various reasons) sysupgrade doesn't work on my new image.

Any thoughts as to a simpler process, ideally just using u-boot's tftp support?

If you can not upload it in openwrt, it will be hard to upload by current uboot, current uboot support max bin file size is 0x3b0000, about 3.6MB, you have to change the source code of uboot make it support larger bin file.(do you try openwrt recover mode? that do not have much driver loaded, should have enough memory for you to download the bin file)

Return to VoCore & VoCore+Dock
