Hi,
as Nikolaus is currently working on improving the voltage connections on the CPU board, it came to our mind that the EVM (which we based our design on) also might have some bugs.
Unfortunately, I don't have an EVM here anymore (it's at the touchscreen manufacturers place so they could test the screen), so I can't help, but as I know some here have an EVM and / or an IGEPv5, maybe you can help.
Here are the issues Nikolaus had that occur both on the EVM AND on the Pyra.
- Unstable at 1,5GHz. Crashes under high-load and when doing memtest.
I have tried with letux-4.9-rc5 (letux defconfig) linus/v4.9-rc5 (omap2plus defconfig) ti/v4.8.3-rt6
That is with DDR voltage fix, right?
yes.
What does "high-load" mean exactly?
Driving both cores to 100% load by running bash in loops:

Well, this might not be an optimal test since in theory every piece could fit in I/D-caches, but it is unlikely.
BR, Nikolaus
