Hi all, I've installed ELDK-3.1 and compiled my u-boot-1.1.1 for PowerPC - 8540,
Which 8540 board do you have? And is that really the official 1.1.1 release? If so, that is old. A lot old. Grab the top of CVS at least. (It should claim to be 1.1.2 though that is just the development of 1.1.2 and not a real official release.)
setting CROSS_COMPILE=ppc_82xx- . and compiled it for e-500.
I didnt see the serial output until I changed the cpu/mpc85xx/config.mk .
I added -mabi=no-spe, (as its recommened by Motorola for 8540/8560) in PLATFORM_RELFLAGS and -mno-string for PLATFORM_CPPFLAGS.
I use these: PLATFORM_RELFLAGS += -fPIC -ffixed-r14 -meabi
PLATFORM_CPPFLAGS += -DCONFIG_MPC85xx -DCONFIG_E500 -ffixed-r2 -ffixed-r29 -Wa,-me500 -msoft-float
Now I could see the serial output and it hangs where the code uses 'sprintf' . This happens only with ELDK-3.1 but also with a toolchain built with gcc-3.3.2 & binutils -2.14.
I dont think its a board problem , as I eliminated the sprintf , the problem is solved at that point and then it hangs at another point where 'sprintf' is used.
I think there is potentially an issue with the location of the string used by sprintf().
I did step through BDI2000 and it crashes at that place.
That's pretty vague... :-)
Do I need to change the compiler flags ..or am I going wrong somewhere.
I'm concerned that you had to change the flags.
I think you should grab the current top of CVS too.
