I add the code below in Cargo.toml

[package.metadata.bootloader]
target="fledgeos.json"

but it still happen the error

Caused by:
    The `bootloader` dependency has not the right format: No `package.metadata.bootloader.target` key found in Cargo.toml of
bootloader

I use bootloader 0.10.6

[package]
name = "fledgeos-1"
version = "0.1.0"
edition = "2018"

[dependencies]
bootloader = "0.10.6"
x86_64 = "0.14.3"

[package.metadata.bootimage]
run-command = ["qemu-system-x86_64.exe", "-drive", "format=raw,file=F:/Rust-In-Action/ch11/fledgeos-1/target/fledge/debug/bootimage-fledgeos-1.bin"]

Are you following https://os.phil-opp.com? If so you need to use bootloader 0.9 and not 0.10.

It seems that bootimage is requiring this entry, and it was removed in 610255e. It works with lower version, but was this change intentional? It was originally added to maintain compatibility based on this commit 33b8ce6. What if I want to use later version of bootloader with bootimage?

[vikigenius]

Yeah, this is problematic I wanted to use 0.10 version to remove the deprecation warnings for llvm_asm! but it doesn't work due to this issue. Any clarification so as to why the entry was removed would be welcome

[bjorn3]

Bootloader 0.10 works in a fundamentally different way to add support for uefi. It for example it doesn't use bootimage at all. Doesn't the latest release in the 0.9 series work without llvm_asm? Does cargo update work?

[vikigenius]

@bjorn3 Nope, even with Cargo update the warning is still there. And it is using the latest version in the 0.9 series: 0.9.19, I checked.

[calebschoepp]

@vikigenius Did you ever manage to get rid of the llvm_asm! warnings?

[vikigenius]

Nope, but I did manage to get the latest version of bootloader working following instructions in the crate documentation.

With #204, I think we can now close this.
