- Great, note that at least for this boot. The ethernet phy came up as address 3 so it would have worked with the original kernel as well.

- Can you provide your 80- number and serial number from the barcode on your devkit?
If you stop at u-boot, does the dhcp command work?
And can you run the config command and give me the output - VK 07:21 PM Software Development: RE: Cannot establish an ethernet connection

- VK 06:52 PM Software Development: RE: Cannot establish an ethernet connection
- Initially, I could connect via a local network, i.e., I just connected the devkit to the router (without changing anything in /etc/network/interfaces or other manipulations). The connection was established without problems. I didn’t even...

So, I tried to set up a newly-bought SD card today. Kernel initialization hung again, but this time, I did not turn it off after that and left it for a while (not inten...

Yeah, this is unexpected. - JC 08:06 PM Software Development: RE: Discussion: Kernel hangs on "Waiting for root device /dev/mmcblk0p1..."

Looking at your log, your kernel build date matches the 2014 MDK so I'm going to assume yes.

For an example of disabling card detect and/or the read-only pin see baseboard_hfm.c:

- That is unexpected. Your boot log looks like everything is correct. It looks similar to if you had no sdcard plugged in at all. Even if you flashed the sdcard incorrectly, I would still expect to see the mmc show up.

Ah, makes sense.
For the time being I'll stick with controlling the clock frequency with Linux.
Thank you for your time.

- MW 07:03 PM Software Development: RE: Increasing CPU clock OMAPL138
- Hi Kim,
I think the reason why the uBoot Critical Link publishes is using 300 MHz is because the Revision 1 silicon was only rated to 300 MHz for 1.2V operation. See Note (7) of section 5.3 of the datasheet. For Revision 1 silicon, ...

- KN 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 can see, according to *Table 6-5. Maximum Internal Clock Frequencies at Each Voltage Operating Point* in *OMAP-L138 C600... - MW 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 PMIC defaults the core voltage to support 300 MHz and I don't think
uBoot adjusts it -- it starts all the PLLs, etc., at... - JC 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 setup by u-boot. But that would need to be tested.
You could use the ONDEMAND governor as default if you want it to sc... - KN 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 hardcoded in the kernel somewhere?
Can't seem to find it.

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.

Thank you for the fast reply :-)
I have the following frequencies available according to the "scaling_available_frequencies" file.

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)?

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.
