At least you no longer get the "broken pipe" warning as your initial report showed, right? > arm-linux-gnueabi-nm: 'arch/arm/boot/compressed/../../../../vmlinux': > No such file That is weird. The Makefile has: cmd_mkxip = $(cmd_objcopy) && $(cmd_deflate_xip_data) $(obj)/xipImage: vmlinux FORCE $(call if_changed,mkxip) So the objcopy must succeed at producing vmlinux for deflate_xip_data (where nm is used) to be called. Do you have a .config for this issue? Nicolas
