2009-08-04 10:15:16     Reg- Patch issue

Hi,

 

I am working on BF527 custom board with 2009R1-RC1 distribution & 2009R1-RC7 toolchain. I have modified the kernel for USB according to BF527 custom board in the downloaded distribution(2009R1-RC1) from https://blackfin.uclinux.org/. This modified distribution named as(for reference only) working_dist. The downloaded distribution names as original_dist.

 

now i have taken the patch between these two distribution with the following command.

 

diff -Naur original_dist  working_dist >kernel.patch

 

Then applying the patch on original_dist  with the following command.

 

patch -fp1<kernel.patch

 

when i try to mount the usb on original_dist uImage, i got the following error.

 

root:/> mount -t vfat /dev/sda1 /mnt/

mount: mounting /dev/sda1 on /mnt/ failed: No such device

root:/>

 

But with the working_dist uImage, i can able to mount the usb.

 

Please let me know if i do anything wrong while taking the patch or applying the patch?

 

Thanks.

Who ever told you your patch method  would work is wrong.

 

It could be almost an infinite number of things.

Dear Robin,

 

could you please suggest the correct method of taking & applying the patch?

 

is taking the patch between two distributions (old and new ) and applying the created patch on the old is proper way?

 

or this creates some problems.

 

Thank you,

There is no automated way. Changes should be limited to config files, not code. Just copy the config files.
