I have bFLT binary (into linux-arm arch.) that I can run with qemu-arm-static .

I want to debug that binary dynamically with GDB.

I know I can debug binary with qemu like qemu-arm-static -g 1111 <binary path>

The problem is that when I run gdb-multiarch with that bFLT binary gdb tell me that <binary path> not in executable format: file format not recognized

How can I debug with GDB bFLT binary?

bFLT format is mostly used by the uCLibc based tool chains and even there the build happens to ELF which is then converted to bFLT, so it’s unlikely you’ll find a GDB which supports bFLT directly. However, you may be able to debug it by attaching to the QEMU’s GDB port (target remote command).

  • So maybe do you know a tool that convert bFLT to ELF? So I will debug it as ELF? Jul 5 at 18:39
  • @yfr24493AzzrggAcom I don't know of such tool and not sure if it's possible; some information is lost completely when converting to bFLT.
