Hi all,
Here's v2 of the pyra-4g ddr3 config. It's now a bit smaller set of changes, and igepv5 configuration is only used for interleaving.
With these changes and the related kernel dts change I can now run two instances of memtester 1900M after I added a heat sink to the CPU board :) It seems that when thermal starts reporting temperatures near 80 C, there can be memtester errors. To verify these really are thermal, I probably need to retest with a heatsink and a fan at some point.
Also when the device it hot, it seems u-boot is having hard time starting after a power cycle with errors like:
SDRAM: identified size not same as expected size identified: 0 expected: 40000000 WARNING: DDR RAM is not working! (12005678)
Waiting 10 - 20 seconds there seems to help with that.
Regards,
Tony
