Patching fails when compiling Openwrt

Tue Jan 22, 2019 12:52 pm

Last night I tried setting up the openwrt dev environment again and one of the first steps was for me to clone the openwrt git and then patch it with I followed the directions exactly and it was all going well until the compilation hit this snag:

Code: Select all
Applying ./patches/0306-spi-flash-factory-id.patch using plaintext:
can't find file to patch at input line 3
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
|--- a/drivers/mtd/devices/m25p80.c
|+++ b/drivers/mtd/devices/m25p80.c
No file to patch.  Skipping patch.
2 out of 2 hunks ignored
Patch failed!  Please fix ./patches/0306-spi-flash-factory-id.patch!

What exactly is this error and why is it happening?

Sorry, I have fixed that patch, it is for spi unique id, just an addition feature, you can remove it if it is still buggy.

And firmware based on openwrt 18.06.1 now is valid.
Please download from, it is based on openwrt 18.06.1
