Hi James,
2007/6/20, James Newell <jnewell@xxxxxxxxx>:
Hello,
First off, I really like the t2 project concept, but I am a complete newbie to
the build system. I was trying to build an embedded generic arm with eabi
support and the uclibc stage 1 fails with svn t2-trunc.

I believe it is failing because the EABI is not selected in the .config for
the uclibc package:
Target ABI
> 1. OABI (CONFIG_ARM_OABI)
2. EABI (CONFIG_ARM_EABI)
choice[1-2?]: 1
Target Processor Type
> 1. Generic Arm (CONFIG_GENERIC_ARM)
2. Arm 610 (CONFIG_ARM610)
3. Arm 710 (CONFIG_ARM710)
I am uncertain on how to make this fix within the context of the t2 build
system.
the arm eabi build option was introduced lately and and so far only
works for glibc.
You may copy the embedded target folder to create a new target for
your platform, add a uclibc.config file in your target folder with the
appropriate rules for your hardware, "X" to select an option and "O"
to disable:
O CONFIG_ARM_OABI
X CONFIG_ARM_EABI
....
Probably you have to select the processor type in this way, too,
because the uclibc cpu options are not (yet) mapped to the T2-SDE cpu
selection.
