32 bit gen_check_code for build kernel

magicse

Linux 32 bit ver. of gen_check_code for building kernel and modules under 32 bit linux.
Download unzip and copy it to
/home/lichee/linux-3.4/arch/arm/mach-sunxi/power/brom
and to
/home/lichee/linux-3.4/arch/arm/mach-sunxi/pm/standby
dirs

I already made a replacement for gen_check_code, called mksunxichecksum, in the kernel patch I uploaded in my OPI2 site http://moinejf.free.fr/opi2/.
The advantage is that you may generate a kernel on the OPI2/plus itself and with a newer compiler (gcc 5.2 is ok).

O nice )
But now I have truble with next error when building uImage.
I get Segmentation fault (core dumped) when arm-linux-gnueabihf-objdump -D arch/arm/mach-sunxi/pm/standby/standby.elf > arch/arm/mach-sunxi/pm/standby/standby.lst
Could you help me?

There should be something wrong in your .config, because, according to

1. arch/arm/mach-sunxi/Makefile

Copy code

there is no generation in arch/arm/mach-sunxi/pm/ for the sun8iw7:

1. ifneq ($(strip $(CONFIG_ARCH_SUN8I)),)
   
2. obj-y += sun8i.o
   
3. obj-$(CONFIG_SW_POWERNOW) += powernow.o
   
4. ifneq ($(strip $(CONFIG_ARCH_SUN8IW7)),)
   
5. obj-$(CONFIG_PM) += power/
   
6. else
   
7. obj-$(CONFIG_PM) += pm/
   
8. endif
   
9. endif

Resolved.
The problems was in
/home/lichee/linux-3.4/arch/arm/mach-sunxi/power/brom
/home/lichee/linux-3.4/arch/arm/mach-sunxi/pm/standby
because there are asm and disasm functions and array allign option for toolchains.
Different toolchains ( gnueabihf 4.4 -4.8) give different errors
But after apply Your patch it's all ok.
uImage compiled well and modules too.

Next riddle - module_layout
For example tv.ko from original Steven Lubuntu 1404 0.9.0
# modprobe --dump-modversions tv.ko
give me next result:  0xa1136ef1 module_layout
And tv.ko from Loboris Lubuntu 1504
give me the same result 0xa1136ef1 module_layout
It's nice ))
But my own module tv.ko that I had built give me 0x9a3f36de module_layout
And this confuses me
