Hi everyone,
I'm new on both Galileo and yocto Linux. I need to manually modify the stmmac driver in yocto Linux kernel (actually just add some debug message). Now I have been able to build the full yocto image and boot it from the SD card. Then I met several question:
1. I found there are two pieces of stmmac source code in the yocto_build directory:
meta-clanton_v1.0.1/yocto_build/tmp/work/i586-poky-linux/linux-libc-headers/3.8-r0/linux-3.8/drivers/net/ethernet/stmicro/stmmac/stmac_main.c
meta-clanton_v1.0.1/yocto_build/tmp/work/clanton-poky-linux/linux-yocto-clanton/3.8-r0/linux/drivers/net/ethernet/stmicro/stmmac/stmac_main.c
The codes in these 2 directories are not exactly same, which is the right one should be updted?
2. After I update the source, how could I rebuild the yocto image? I have updated above 2 files and reexecute "bitbake image-full-galileo" but it doesn't work, it there any other steps I need to do?
