It is possible to boot the system on Microblaze but it is impossible to login (getty shows prompt without hostname: "(none) login:" and it always fails). A similar behaviour was seen a while before with one of the Xilinx toolchains (14.3?). We tried to hack into the system from an init script by starting a shell. This failed with Illegal instruction exception. Another strange thing happens while calling "ls -l /". It lists all the filesystem recursively (I suppose, this is wrong as well). Do you have any idea how to debug it? (qemu + gdb?) Regards Jan Viktorin
