Hi All,
I am not having any success in flashing 8.09 to NAND on this unit. It loads the .bin file to CF and works OK, but I get kernel panic when I try to netboot (openwrt-rb532-vmlinux). I have tried more than one snapshot fileas well as  8.09.1 and 8.09.2-RC2.  I have even compiled it myself and I keep getting
"Kernel panic - not syncing: No init found.  Try passing init= option to kernel."

Am I doing something wrong??

See my output below.

Thanks in advance.

I have been compiling my own images and can now load the new image. However when I try to boot the image, here is what I get,  "FPU emulator disabled, make sure your toolchain was compiled with software floating point support (soft-float)".

Has anyone else tried this before? I am tying to figure out what adjustments to make but no luck so far. Any ideas??

Thanks

FPU emulator disabled, make sure your toolchainwas compiled with software floating point support (soft-float)

I have exactly the same error on a RB411 compiling my image from trunk. The message repeats itself every time i alter the status of one of the wifi interfaces.

Could anyone direct us to the relevan menu option ?

Edit :
Digging into the developers menu , i found this , already marked as yes

CONFIG_SOFT_FLOAT:
                                 
If your target CPU does not have a Floating Point Unit (FPU) or a kernel FPU emulator, but you still wish to support floating point  functions, then everything will need to be compiled with soft floating point support (-msoft-float).
Most people will answer N.
Symbol: SOFT_FLOAT [=y]
Prompt: Use software floating point by default
Defined at Config.in:332
Depends on: (arm || armeb || powerpc || mipsel || mips) && !HAS_FPU && TARGET_OPTIONS
Location:
     -> Advanced configuration options (for developers) (DEVEL [=y])
