Hello to everyone,
Few weeks ago, I've followed a thread on this list regarding the toolchain should be used to compile code for omap 35xx. Surfing on the net, I've also found a msg of Koen Kooi where he described a patch to be applied on /arch/arm/Makefile in order to let gcc 4.3.x work.
Now I am not an expert of toolchain and I didn't understand what is the actual status, thus my question is: may I use the toolchain coming with the ELDK 4.2 to compile for omap35xx or do I have to apply some patches?
I don't know toolchain coming with ELDK 4.2, but for U-Boot for OMAP 35x you don't need a special compiler. A non-broken arm-linux-gcc or similar will work. While bringing OMAP U-Boot support to mainline, we explicitly switched to a more conservative toolchain configuration (-march=armv5 instead of v7a) to enable more toolchains to work.
Try the toolchain you have and ask or report errors if it doesn't work.
Best regards
Dirk
Btw.: For other code, e.g. Linux user space programs which need special optimizations, other toolchain might be necessary, though.
