Hello,
It seems that all three ARM errata workarounds done in omap3 board-init (#454179 #430973 #621766) are solved/not longer needed e.g. in the AM/DM37xx chips. Other people have noticed this: http://e2e.ti.com/support/arm/sitara_arm/f/791/t/254742.aspx
When still applying them (especcially #430973), lots of segmentations faults and other strange stuff begin to appear.
I read your link the other way round. If the #430973 errata fix is _not_ applied to r3p2 it gives a lot of segfaults. Unfortunately the thread has noc more information on that.
#430973 is still needed on latest Cortex-A8 silicon of DM3730 according to my testing; this is in contradiction to what TI and ARM claim
I dont know what bootloader the guy used, but he states that he needs to enable the errata fix in the kernel for the segfaults to disappear. I
the guy used u-boot 2012.10 and linux 3.7 :)
found exactly the same: Initially I had no errata fixes configured for the kernel, only when I added them the segfaults disappeared. However they also disappear if I remove the workarounds from kernel as well as u-boot, hence this patch.
interesting; I did not consider this dependency between u-boot and kernel here; will try it
regards, p.
