I have a kernel for a new board (Linux 2.6.14.5, Pico E12/Xilinx V4 PPC405) booting to the point of starting /init.
/init appears to be getting loaded correctly - the execve call seems happy. But I get no output on the console. I have tried: executing sys_write(1,"Test",4); inside init/main.c immediately before starting /init - works fine. starting a "hello World" application written in PPC asm as /init - works fine. The kernel panics on exit but that is normal, /init is not supposed to exit. starting a c "Hello World" application that uses glibc, fputs, printf, fwrite, to display a string - again works fine. But I can not get busybox to output a thing either run as /init or run as /bin/sh. I have aslo tried /bin/sash - no output. I have even cross compiled sash - with all kinds of "I am here" debugging scattered through main(), If I runn it on a powerbook, I get what I expect. If I run it as /bin/sh on the e12 I get no output. Does anyone even have any ideas what I can look at ?
