Kernel panic - not syncing: No init found.

After successfully starting the kernel I get an error message  

Kernel panic - not syncing: No init found.  Try passing init= option to kernel. 

 

After mounting the rootfs it can't find the the init in /bin/init. I mounted the flash image as loop device and everthing seems ok. The init file is in /bin, it is executable and /bin is accessableand the flash image is at address 0x200000. So I don't see, where the problem could be! Even when I pass the boot option init=/bin/sh, the error occurs.

Re: Kernel panic - not syncing: No init found.

Hi... how about you send me your romfs image? I can take a peek and try mounting it on one of our dev boards here. I'll send you my e-mail address via pm.

Re: Kernel panic - not syncing: No init found.

After building the same kernel with ethernet support, I get a slightly different output: 

Freeing unused kernel memory: 64k freed (0x217c000 - 0x218b000) Warning: unable to open an initial console. Kernel panic - not syncing: No init found.  Try passing init= option to kernel. 

 

Now I get the warning, that the initial console could not be opened. The console is JTAG-UART. The device file has major,minor 5,1.
