Hi,
I am trying to make custom mtd module, to expand the mtd devices to read whole nand and i am using as an example msm_nand.c
So what i have done is added a few devices to mtd partition and compiled. But at the compilation ld says msm_dmov_exec_cmd in not found.. Does not sound good, because original msm_nand.c compiled good as well as the whole kernel.
Could someone help me?
Here is the code i added, i left last lines from the original and my addition due to the code length restriction here:
Code:
/* drivers/mtd/devices/msm_nand.c
.....
msm_nand_release_ex(&info->mtd);
dma_free_coherent(/*dev*/ NULL, SZ_4K,
info->msm_nand.dma_buffer,
info->msm_nand.dma_addr);
kfree(info);
}
return 0;
}

And also i get in dmesg weird message that my kernel version string is wrong, though i used same kernel except the last modification string. And i can't find any other kernel..
Thanks guys!
you should edit the Makefile and set
EXTRAVERSION = <your kernel version>.
Yes i managed to bypass it but the insmod then says msm_dmov_exec_cmd is not found..
Weird..

Hey,
I think we have completely stolen the other thread about CWM for our device (SM-G350).
So I started a new one dedicated to development of this phone.
Currently I'm trying to port CyanogenMod 10.1 (4.2.2JB) from Trivalent's source code in GitHub. (Thanks to warlinegtr for finding it)
IF you have any skills that might help with this project, please contact me.
And please don't post links to some basic tutorials, I have already read them.
You can freely post source code that might help us in the future.
Regards, santeri3700
Status 12.9.2015 (DD/MM/YYYY)
Current issue: CM10.1 Cannot boot because of the wrong CWM made for cm_mint. It overwrites init.rc and adds wrong fstab to the system partition.
My own built CWM has graphical bug. Half the screen is black and other half is stretched and pink-ish. Still possible to operate.
