Segfault with GCC in Armbian [Solved].
#14
This is a followup post to to confirm that the Rock64 board that was experiencing segmentation faults with the default 786 MHz memory clock on Armbian is now stable with the uboot-initialized 333 MHz setting.

On a selection of computational benchmarks performance is about 77 percent of the original setting;

for compilations with gcc more than 80 percent of the original performance is retained with the added advantage that the system doesn't crash and the compiler doesn't create segmentation faults.

I understand, but did not verify, that setting the memory clocks to 333 MHz has a noticeable affect on video playback.

As far as I'm concerned this problem is solved and I'll try to mark it as such. Although one out of the two Rock64 single-board computers I have required this configuration change, based on posts appearing on this forum, my suspicion is a much less than 50 percent--perhaps closer to 10 or 20 percent--of systems in use actually exhibit this problem.

Even so, I would favor a note on the wiki support page for the Rock64 explaining how to work around system instability by reducing the DDR RAM memory clock.
