Hi Mark,

I’ve a cross compile environment.

-a arm is necessary to choose the right architecture.
-B CROSS_COMPILE=arm-none-linux-gnueabi- sets the compiler prefix for the Linux kernel compilation.

-B CONFIG_DEBUG_INFO=y is not necessary.

The target architecture is 32bit ARM. The host architecture is 64bit X86. That’s the reason why field .sec_load_offset is initialised with a 64bit wide hexadecimal number. But as the field .sec_load_offset is defined only as „unsigned long“, the compiler complains. As a work around I tried to output decimal number instead for the initialisation of .sec_load_offset. I can compile alright. But the resulting backtrace calculations shown in my previous example produce strange results.

Kind Regards,
Torsten
