Hello U-Boot list members! There exist an issue with the newly GNU binutils version 2.44 when trying to build U-Boot at link time.
Error output: $ make stm32h743-eval_defconfig $ make [...] LD u-boot arm-none-eabi-ld.bfd: warning: -z norelro ignored arm-none-eabi-ld.bfd: arch/arm/cpu/armv7m/start.o(c_runtime_cpu_setup): Unknown destination type (ARM/Thumb) in arch/arm/lib/crt0.o arch/arm/lib/crt0.o: in function `_main': /home/jk/Projects/U-Boot/src/arch/arm/lib/crt0.S:170:(.text+0x44): dangerous relocation: unsupported relocation make[1]: *** [/home/jk/Projects/U-Boot/src/Makefile:1824: u-boot] Error 1 make[1]: Leaving directory '/home/jk/Projects/U-Boot/build' make: *** [Makefile:177: sub-make] Error 2 $ I have tried to fixed it with success. Simply added the assembler directive ".type c_runtime_cpu_setup, %function" after ".globl c_runtime_cpu_setup". under the path: arch/arm/cpu/armv7m/start.S The binutils patch with cause this building error is explained at least in the following commit in the binutils git repo: 31ed3a9d691493486f6e32357d89a55229dbdc0a Extract from the log: "This patch emits an error instead, and warns in some other cases, to encourage users to add the missing '.type foo,%function' directive." But I don't know if this only exist on ARMv7-M. Kind regards, Johannes
