Compiling ARMv7 on dragonboard410c


It is written in the dragonboard410c spec that it supports also arm 32.
Is it possible to use the code in
to compile the kernel for arm ? and if so, what should be the $ARCH and the $CROSS_COMPILE ?


Possible but only in the sense that it is “just software”; there are no instructions for acheive it and this mode of operation is not supported.

In generally if you want to run 32-bit ARM applications you are better off using a 64-bit kernel with 32-bit syscall support (I think the DB410C kernel will already have this enabled).

I think you could either install a 32-bit rootfs or, if you configure apt properly, pull in just the 32-bit libraries you need (same as 32-bit support on x86-64).
