Comment(by Vladimir.Koutny):

 I have a unit from the same ( delivery as Richard and I don't
 see any memory issues (yet). However, I also can't run mtest in the full
 range - the range that doesn't cause crash/han
 g is:
   30000040 - 33e80000
   34008000 - 38000000
 (btw. first 0x40 bytes contains vector table - I guess you don't want to
 mtest that area :) )

 That might be influenced by uboot version - in my case it is 1.3.2-rc2
 -dirty-moko12 (NAND) and 1.3.2-moko12 (NOR) (both as shipped), not sure
 where uboot code/data are mapped.

 Btw., when looking at Freerunner memory map at, I would guess
 that external ram chip would be mapped starting at 38000000...
