trimming internal oscillator

Florijan — Fri, 10 Oct 2014 10:11:17 GMT

Hi,

does anybody know how to configure the P&E Universal Multilink inside KDS to trim MCU's internal oscillator to desired frequency? In CW10.x you could do it very easily using "advanced settings" in P&E debugger's menu. But in KDS there is no such menu.

Best regards,

Florijan

hello Florijan,

from my understanding, KDS doesn't have this feature. user who need trim internal clock please do it in pe setting as below:

Hi Florijan,

that's not directly possible in the P&E UI. I had a similar challenge with the flash block memory perserve.

I have found a way to do this with modifying the .arp file, see

Preserving Memory Ranges with Eclipse and P&E GDB Server | MCU on Eclipse

I see that the TRIM value is in the .arp file too. I have not tried to change it, but this might be a possible way for you.

Hi Zhang ZhangJennie

on mkl25z128 mcu this seems to work but not on the mke06z128. The internal clock on mke06z128 is about 20% faster than it should be and if debugger is connected to it it works on as slightly different frequency than if it runs without debugger.

Best regards,

Florijan

Hi Erich,

I think I will have to use this method until better support for internal clock trimming is provided.

Best regards,
