- KN 12:52 PM Software Development: RE: Changes on MityDSP-L138 L138-DM-336-RI-J
- Hi Mike,
Thank you very much for the fast response.
We are loading the FPGA from Linux, but not with the "fpga_ctrl.ko" kernel module mentioned in the "Programming the FPGA" wiki.
Unfortunately, that kernel module is not part of o... - MW 10:13 AM Software Development: RE: Changes on MityDSP-L138 L138-DM-336-RI-J
- Have you reviewed the migration information (including the PCN) from this page?

I have received a new MityDSP-L138 SoM board:
* Model no: L138-DM-336-RI-J
* Serial no: 22023557
* Part no: 80-001541RI-2A
The new SoM includes an Artix 7 FPGA and I am curious to know if there are any software changes (U-Bo...

- 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...
- JC 05:35 PM Software Development: RE: Cannot establish an ethernet connection
- I'm sorry, but you need to answer my questions if we are going to get to the bottom of this.
- VK 04:49 PM Software Development: RE: Cannot establish an ethernet connection
- The output I obtained now is in the attached file. Now I want to connect directly to the PC to eliminate router influence. May I do any specific actions? I have tried to do it (like I did with raspberry pi before, for example) but achiev...
- VK 03:39 PM Software Development: RE: Discussion: Kernel hangs on "Waiting for root device /dev/mmcblk0p1..."
- Hello, I'm sorry for the delay. I have reprogrammed u-boot as you advised. Loading from a "guilty" SD card is as fast as before, with no freezes. The only problem that returns is that I cannot establish an ethernet connection again (for ...

The next thing we should try is reprogramming u-boot and the ubl. Since we've tried several SD cards and... - VK 11:45 AM Software Development: RE: Discussion: Kernel hangs on "Waiting for root device /dev/mmcblk0p1..."
- Yes, the md5 sum and all installation process outputs are equal.
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.

- Thanks for the update.
Did you grab the mityomap-full.tgz file from MDK_2014-01-13? I just want to follow the same steps and make sure it still works on my end. - VK 06:02 PM Software Development: RE: Discussion: Kernel hangs on "Waiting for root device /dev/mmcblk0p1..."
- Sorry if I have described my problem not clearly. Yes, I booted this devkit successfully with my sd card before (about a month ago). Nobody except me worked with this devkit. The kernel is without any changes from my side. I use the defa...

- If this is a custom baseboard without the card detect hooked up. Then this could also happen.
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.
Example of succ... - I made rootfs on an SD card according to this wiki page (https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Linux_Root_File_System), but every time kernel hanging on "Waiting for root device /dev/mmcblk0p1...". The ful...

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, ...
