This goes hand-in-hand with the kernel update. The version is taken from meta-ti. The new kernel version, 3.12, requires a newer PM FW. This should correspond to v05.00.00.02, though that tag has not been pushed...

Enforce correct -march option
|
|
|
|
Buildroot uses a normal ARM compiler to build the AM33X CM3 firmware
|
|
(which runs on a Cortex-M3 processor), but Buildroot will have a
|
|
default -march value that doesn't necessarily match the one needed for
|
|
Cortex-M3, leading to build failures (gcc complains that the
|
|
-mcpu=cortex-m3 option being passed is not compatible with the
|
|
selected -march).
|
|
|
|
Fix this by explicitly indicating -march=armv7-m.
