Gotcha, just curious if your based off of 4.19 from mainline or if you started from a TI kernel. Glad you got it working though. - KN 12:21 PM Software Development: RE: Increasing CPU clock OMAPL138
- It's our own "experimental" kernel.
It seems to be working now. The issue was that the pll0 registers were apparently locked by CFGCHIP0.
Thank you for your time.

- Where is the 4.19 kernel based from? It doesn't appear to have working cpufreq.

- Hi Mike & Jonathan,
Thank you for the fast reply :-)
I have the following frequencies available according to the "scaling_available_frequencies" file.
456000 408000 372000 300000 200000 96000
We are actually using a newer kerne...

- Hi Kim, What kernel version are you using? Testing this on our released 3.2 kernel appears to be working for me.
Note my module tested is only rated up to 372000khz. I can try to find a L138-F... module which should be good up to 45... - MW 05:23 PM Software Development: RE: Increasing CPU clock OMAPL138
- Hi Kim,
What do you get when you dump out the scaling_available_frequencies (I don't remember the exact name off the top of my head, but the file that lists the available frequencies that may be selected)?

- Hi,
I'm using a "L138-FI-236-RL" SOM board with SYS/BIOS running on the DSP and Linux on the ARM.
The Linux is built by ourselves, but it is based on davinci Linux.
I have attached the config file I use and dmesg log.
Issue:
