[Solved] Upgrade to 16M target from 8M

I upgraded an old openwrt on vocore to lede-17.01.4-ramips-rt305x-vocore-8M-squashfs-sysupgrade.bin, but then discovered I have the right chip for lede-17.01.4-ramips-rt305x-vocore-16M-squashfs-sysupgrade.bin.

In the web interface, however, attempting to upgrade yields the messge "The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform." The sha256sum is correct, how to proceed?

Thanks, ended up copying the image to /tmp, and doing

# mtd -e firmware write /tmp/vc.bin firmware
all is well.

note that

# sysupgrade /tmp/vc.bin firmware
failed with "Invalid image type."

Likely because you need to use the system.img, not sysupgrade.bin
