STILL soft float toolchain problems on ARM
Hi there!
I'm still trying to get a working buildroot for my ARM platform (EP9302 cirrus logic CPU, T920), with soft float enabled. My configuration uses GCC 4.1.2, libfloat, soft float and uclibc 0.9.29 (i tried both snapshots and 0.9.29 official release).
I'm using last buildroot snapshot, and i tried EVERY configuration with soft floats but nothing worked because of an error compiling uclibc-0.9.29. I went to uclibc folder and i tryied to finish build, then i got these lines:
LD libuClibc-0.9.29.so

make[2]: *** [lib/libc.so] Error 1

Can anyone help me fixing that?

Hi there!
I'm still trying to get a working buildroot for my ARM platform (EP9302 cirrus logic CPU, T920), with soft float enabled. My configuration uses GCC 4.1.2, libfloat, soft float and uclibc 0.9.29 (i tried both snapshots and 0.9.29 official release).
I flagged several such reports with FLOAT in the subject. Can you provide me with a kernel-config that i can use with qemu that does:
1) use xscale (but t920 t926 should do too, if you prefer)
2) have framebuffer support
3) is noMMU
4) wants soft-float
perhaps we can get this going again

I cannot provide such kernel config because i dont use XScale, but cirrus ep93xx. I dont understand why are you using QEMU to test these...
I'm using qemu because i don't have such hardware, that simple ;)
If i don't have a kernel that i can use for testing, i'm not interrested, thanks.

I'm simply trying to compile last buildroot snapshot WITHOUT changing any kernel configuration.
good luck
Paolo,
I've found that when changing some of the build options you need to make sure you do a make clean and then remove the build_arm_nofpu and toolchain_build_arm_nofpu directories because they are not always purged properly.
Don't get discouraged, I'm also working on the EP9302 and am not utilizing the FPU.
Here is my config.
Stuart
