Re: [PATCH 2/2] LC15: Increase T_RFC to fix 4GB kernel memory errors

* Tony Lindgren tony@atomide.com [180531 20:28]:

Yeah seems to work reliably based on about an hour of testing with fans running at higher voltage. I'm seeing these temperatures:

/sys/class/thermal/thermal_zone0/temp 64026 /sys/class/thermal/thermal_zone1/temp 60677 /sys/class/thermal/thermal_zone2/temp 60600

Will try doubling the refresh rate next without fans.

No luck playing with EMIF_SDRAM_REFRESH_CONTROL without fans. I start seeing memory errors at temperatures around 70.

If found a page discussing these register values here if somebody wants to experiment with it:
