05:50 AM Software Development: RE: Discussion: Kernel hangs on "Waiting for root device /dev/mmcblk0p1..."
I use the standard devkit. When I had problems with the SD card (for example, bad partition), I got these messages:

If this is a custom baseboard without the card detect hooked up. Then this could also happen.
For an example of d...

That is unexpected. Your boot log looks like everything is correct. It looks similar to if you had no sdcard plugged... Jonathan Cormier

I made rootfs on an SD card according to this wiki page (https://support.criticallink.com/redmine/projects/arm9-platf... Vadym Kolesnyk

Hi Mike,
Ah, makes sense.
For the time being I'll stick with controlling the clock frequency with Linux.
Thank...

Hi Kim,
I think the reason why the uBoot Critical Link publishes is using 300 MHz is because the Revision 1 silico...

02:12 PM Software Development: RE: Increasing CPU clock OMAPL138
Alright.
Is there is no way to change the default frequency from 300Mhz to e.g. 372MHz with U-Boot?
As far as I ...

02:01 PM Software Development: RE: Increasing CPU clock OMAPL138
Hi Kim,
I think the issue is that the voltage scaling needs to be done to default
to a higher frequency.
The P...

02:00 PM Software Development: RE: Increasing CPU clock OMAPL138
I don't see an obvious default frequency config in the kernel, I'd guess that it stays with whatever frequency was se... Jonathan Cormier
01:44 PM Software Development: RE: Increasing CPU clock OMAPL138
I actually got another question.
By default, the cpu frequency seems to always be 300 MHz.
Is this value hardco...

It's our own "experimental" kernel.
It seems to be working now. The issue was that the pll0 registers were apparentl...

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

Hi Mike & Jonathan,
Thank you for the fast reply :-)
I have the following frequencies available according to th...

Hi Kim, What kernel version are you using? Testing this on our released 3.2 kernel appears to be working for me.

Hi Kim,
What do you get when you dump out the scaling_available_frequencies (I don't remember the exact name off t...

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 bu...
