The problem must be at your end, especially if the toolchain exhibits segmentation faults. Following exactly the instructions above, I get: [...] LD vmlinux SORTEX vmlinux SYSMAP System.map OBJCOPY arch/microblaze/boot/linux.bin Building modules, stage 2. MODPOST 3 modules CC crypto/drbg.mod.o CC crypto/echainiv.mod.o CC crypto/jitterentropy_rng.mod.o LD [M] crypto/jitterentropy_rng.ko LD [M] crypto/drbg.ko LD [M] crypto/echainiv.ko Kernel: arch/microblaze/boot/linux.bin is ready (#1) Nicolas
