I mistakenly thought my kernel was EABI, and that both my toolchains were EABI, and didn't realize that apcs-gnu meant ARM OABI. > are you sure you have enabled that in CT-NG? > Any reason why you are not using EABI? I starting using a default config from Atmel that was OABI. I switched to EABI, but at some point had switched back (and either didn't know or forgot). Everything really is EABI now, and things are working again. -- Grant Edwards grant.b.edwards Yow! Did I SELL OUT yet?? at gmail.com
