hi all,
i add some work with imx6 and ddr stress test,
the test failed in high temperature above 80 c and i think it's because of the change in the cpu frequency.
i nodes that there is 2 threshold:
passive & critical, and i'm sure i worked above the passive threshold - 80.
i would like to know what is the specific value of the frequency cpu in this mode?
(when the cpu decided to change the frq)
i like to get some table that show frq VS temp
best regards
GG
Hi Barak
cpu frequency changing behaviour is described in
AN4579 i.MX 6 Series Thermal Management Guidelines
https://www.nxp.com/docs/en/application-note/AN4579.pdf
Failures at higher temperatures may mean that the drive strength is too low
and the signals may not rise/fall fast enough.
Best regards
igor
