I've tried what you suggested, linking the boot.rel first results in the opposite effect, the _START area gets overwritten by the _CODE area. Here a small showcase for the problem I'm having: ; boot.asm: .globl HexToU8 .area _START (ABS,OVR) .org 0 ldSP, #0x call

While I don't have sdcc loaded at the moment, and haven't used it for Z80, isn't the OVR in .area _START (ABS,OVR) indicating that that segment can be overlayed (which is not what you want)? I'd check the linker manual or just try removing it and see if your problem goes away. Peter Van
