Hello,
I’ve build a custom toolchain using crosstool-ng with uClibc for imx28. Work fine excep for some c++ aplications that crash into a segment fault.
I suspect that I’m missing some compiler flag that lead to a bad eabi link.
The flags that I’m using are:
-march=armv5te
-mtune=arm9tdmi
-mfloat-abi=soft
Are they correct?
Am I omitting any other crucial flag?
I find that -mtune could be also arm926ej-s. Which one is correct for imx28?
Thanks in advance
jordi
Hi Octavio,
I have not yet worked with yocto
I've used cosstol-ng (from http://crosstool-ng.org/) as explained in imx28 bsp documentation gcc4.4.4_multilib_toolchain_release_note.pdf. I’ve configured for uClibc, disabled multilib mode, and added flags of above...
The strange thing is that everything works fine (kernel, busybox …) except for some c++ applications that cause next execution error:
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Aborted
And sometimes segment fault
