@JeffZhou, it's worth noting that the stock OpenWrt DTS available from Onion does have it set to 40MHz , probably for this exact reason, so it's not a problem for normal builds from the Onion repository. Only when you start to push the boundaries does the issue become apparent. The flash chip itself is rated to 120MHz (I think) so you'll forgive my temptation to try and run it harder rather than settle for 1/3rd of the rated speed

Hi, @JeffZhou, all boards use the Omega2S+version. The prototype is almost the same, just a couple of unrelated circuit changes. It does look like the problem goes away running the flash at 40MHz (max) in the DTS. I was trying to push the limits so I think it's down to silicon variation, some are happy at that speed/temperature some aren't. Thanks.
