- Hi Kim,
I am relieved you got your system loaded.
Have a nice weekend.
With regards,
Mike - KN 08:57 AM Software Development: RE: Changes on MityDSP-L138 L138-DM-336-RI-J
- Hi again,
We managed to fix our loading problem.
The bug was due to our FPGA binary, not the loader itself.

- Hi Mike,
I tried to build the fpga_ctrl.ko module, but nothing seems to happen when I try to program the FPGA.
*Loading the FPGA with fpga_ctrl.ko*
These are the commands I use:
$ insmod fpga_ctrl.ko
$ echo "1" > /sys/devices/fp...

- 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
- I use critical link industrial io baseboard
- 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 ...

Okay that is good

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...
