- --with-multilib-list=armv6-m,armv7-m,armv7e-m,armv7-r
+ --with-multilib-list=rmprofile
rmprofile 对应的是 armv6s-m,armv7-m,armv7e-m,armv8-m.base,armv8-m.main,armv7 并没有需要的armv6-m
谢谢
The following machine turn
I checked diff to make sure that the problem was caused by this change:
- --with-multilib-list=armv6-m,armv7-m,armv7e-m,armv7-r
+ --with-multilib-list=rmprofile
The corresponding rmprofile is armv6s-m, armv7-m, armv7e-m, armv8-m.base, armv8-m.main, armv7 does not need armv6-m
Thank you
Here is similar discussion https://bugs.launchpad.net/gcc-arm-embedded/+bug/1449610 and it seems that GCC should work even for "armv6-m" arch. Sounds like it could be a GCC issue and worth clarifying with upstream.
