Thank u! I just want to make a test before i modify content of files such as ep405.c . and i changed the directory as you said to board/ and modified the Makefile correctly. then , #make clean #make ep405_config #make all the error followed is : make[1]: Entering directory `/tmp/u-boot-1.1.4/board/ep405' make[1]: *** No rule to make target `../common/misc.c', needed by `.depend'. Stop.
so now, where will i check the rule and do some amendments and how to do?
I also confused by another problem: There has been a PlanetCore Boot Loader resides in flash memoery(in EP405),and there is no JTAG on the board. so if i erase the existed bootloader which is convinient for writing flash, it will be difficult for me to write my u-boot image to flash. so can i keep the existed bootloader and as it is now and use it to write u-boot in another region of the flash ? Then after booting from PlanetCore Boot Loader, i will be able to run u-boot and check if it has been correctly modified. if the answer is yes, what should i do during the procedure of modifying u-boot?

Thank you so much for answering my questions i mentioned several days=
ago. I'm porting u-boot-1.1.4 to Ebedded planet EP405(with ppc 405GPr processor) and it bases on a similar board CPCI4052 as you suggested.
Let's keep in mind that similar does not mean the same.
#cd ../u-boot-1.1.3/board/esd #mkdir ep405This is wrong. Don't do this. "board/esd" is for boards manufactured by esd electronics only, while the EP405 is by Embedded Planet. So far we don't have a vendor directory for EP, which means you have to place your code in board/
then add text content as follow to u-boot-1.1.3/Makefile ep_config: unconfig @./mkconfig $(@:_config=) ppc ppc4xx cpci405 esd
Wrong again, as you must provide your own board config file instead of using the cpci405 one.
would you please tell me why and how to handle it ?
Clean up above problems first, please.
Best regards,
Wolfgang Denk
