Overheating processor

I think this will help.

DVFC: Version 1.0, ActiveKey = Drivers\Active\58

ERROR: c:\wince800\platform\fsimx6\src\drivers\dvfc\efusa9\voltctrl.c line 89: DVFC: DVS_PIN_EFUS=240 not supported by CEDDK!

ERROR: c:\wince800\platform\fsimx6\src\drivers\dvfc\common\dvfc.c line 1184: DvfcInitVoltageSupplies failed!

ERROR: c:\wince800\platform\common\src\soc\fslcomm_fs_v1\dvfc\dvfc.c line 294: BSPDvfcInit failed!

The hardware revision looks fine.

HW rev. 1.20

The dll is in the ffsdisk folder.

I have

efusA9 V2.40 - Firmware Init

quad core

Yes this helps. My fault. Looks like instalion of dvfc is not sufficient, you need also an updated ceddk.

I will provide you a new custom kernel with dvfc and ceddk and will come back.

Hello, you can download new kernel (220818) from you custom download area.

Hope it works now, "core clock" should show 400MHz, head should be reduced.

Does it take time to come available? I navigated to

My F&S -> efusA9 -> WinCE -> WEC2013 -> Kernel

but I can’t find 220818.

fs-support_ZU · Aug 18th 2022

No it should be available but under your custom download folder "deroeve", here are all your images since 2016 are available. If you have no access to this folder contact goretzka@fs-net.de.

Ok the clock frequency is at 400MHz. I will do further tests with this clock frequency. Thanks.

One more question.

We worked with version 180316 and I see that this version is skipped in the kernel history?

gert.janssens@deroeve.com · Aug 18th 2022

I also see that the binary was named 220816 instead of 220818?

fs-support_ZU · Aug 18th 2022

Yes, sorry but it should be the correct image and the date in serial debug output should be 220818.

>> We worked with version 180316 and I see that this version is skipped in the kernel history?

<< You are right. But I found no information about the changes also not im my emails from around 180316.

So we unfortuneatly lost this information.

gert.janssens@deroeve.com · Aug 19th 2022

I performed some tests but I do not see any difference in core temperature with the 400MHz version. Any idea how this is possible?

fs-support_ZU · Aug 19th 2022

>> Any idea how this is possible?

<< Maybe a bug in my SW. Sorry I have to measure and debug to step further.

fs-support_ZU · Sep 19th 2022

Sorry i don't step further in the meanwhile.

I am bound on some other urgent projects.

Is this issue still significant for you? I can spend some more time start in KW42/22
