U-boot Error Message
Added by Jose Berlioz about 3 years ago
Hello,
I am new to the HPS system and I was going through the guide for making U-boot and SD card provided after creating a design file in Quartus, but I always get the error message attached below. Have you encountered this error and can you provide some guidance?
Here's my UbootEnv:

Hi Jose,
I'm going to need a bit more info to help you get further. Can you provide your full console log? Also is the ubootenv you provided a copy and pasted from the uBootMMCEnv.txt file or is it the print out of running "print env" from u-boot? If it's a copy and paste from the text file could you also provide the output of running "print env" in your console log.
Thank you!
Dan

RE: U-boot Error Message - Added by Zachary Miller about 3 years ago
Hi Jose,
I think your U-Boot environment may have become corrupted somehow: the "bad partition specification" error can occur when the partition number doesn't parse correctly. Since it looks right in the error message, I suspect there may be invisible control characters in the mmcextpart
variable.
You'll most likely need to reflash your SD card (or at least the U-Boot environment: Building_sd_181). It looks like you're using our stock U-Boot environment, so I'm attaching a known-good ubootenv.bin
you can use for reflashing.
If you were editing environment variables at all from U-Boot (with editenv
or setenv
), this could also have happened by hitting a key U-Boot doesn't handle well (e.g., the function keys).

RE: U-boot Error Message - Added by Jose Berlioz almost 3 years ago
Hey Zach,
Thanks for the ubootenv.bin file, that seem to have done the trick and I was able to load the fpga image. I seem to have issues with the kernel though.
The console freezes at the end and Yocto never loads. I am using the mitysom-image-base-mitysom-c5.tar.gz provided on the website.

RE: U-boot Error Message - Added by Zachary Miller almost 3 years ago
Great, I'm glad that helped!
Is "starting kernel" as far as it boots? As a quick sanity check, could you try flashing a fresh SD card from the pre-built image on our wiki? There are download links here: wiki (based on your U-Boot environment, it looks like you want the "5CSX-H6-42A SD Card" link).
Assuming that works, we should be able to work backward and figure out what piece is causing the issue. Could you please also describe your build setup a bit? Namely:
- Are you on Windows or Linux?
- What version of Quartus are you using?
- What components of the SD card have you rebuilt (preloader, U-Boot, FPGA)?
RE: U-boot Error Message - Added by Jose Berlioz almost 3 years ago
Hey Zachary,
Thanks for your help. Yes, that's as far as it goes. I flashed on a different SD Card and it has the same issue. Also, I can flash it with a working SD card img from criticalLink and that one loads.
Answering your questions:
1) I use the xubuntu VM given by criticalLink to run build the preloader and uboot and run the make_sd.sh script. I use Windows to work on Quartus and use the bsp-editor for the handoff, and I use Win32DiskImager to load the image to the SD Card.
2) I am using Quartus 18.1
3) I rebuilt the fpga and added a 32 bit lwbridge and an 128-bit AXI bus to the HPS,
plus the U-boot and preloader following https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki/Building_uboot_181. Maybe I miss something given that I changed the HPS?

RE: U-boot Error Message - Added by Zachary Miller almost 3 years ago
Hi Jose,
Thanks for the info. When you rebuilt your SD card image, you included your all three of your new preloader, U-Boot, and FPGA, correct? If there's a mismatch between those three binaries it can cause the kernel to hang like this, particularly when the bridges to the HPS have been changed.
As another sanity check, when it gets to trying to boot the kernel, does the yellow LED on the SOM turn off? (There should still be a green LED next to it that stays on.) Based on your log, I expect the yellow LED to turn off, but if it doesn't, then the FPGA isn't loading properly (which could also cause this hang).
Would it also be possible to zip up your SD card image that hangs and post it here for us to take a look?
Zach
RE: U-boot Error Message - Added by Jose Berlioz almost 3 years ago
Hey Zach,
I included all three in the SD Card when I rebuild the SD Card. Also, the SOM yellow LED turns off and the green LED turns on.
Sure, I can do that. I am including a zip file with the SD Card Image and the individual files and the make_sd.sh script used.

RE: U-boot Error Message - Added by Zachary Miller almost 3 years ago
Hi Jose,
The issue is device tree nodes for FPGA peripherals that don't exist in your FPGA. As a quick-fix, I'm attaching a precompiled device tree you can include in the filesystem to make your SD card boot. You'll want put the device tree in your build location at the path overlay/boot/socfpga_mitysom5csx_devkit.dtb
. Then when you run make_sd.sh, add the options -r overlay
. So for example the full command would be:
./make_sd.sh -d CycloneV -p preloader-mkpimage.bin -u u-boot.img -e ubootenv.bin -f dev_5cs.rbf -r overlay mitysom-image-base-mitysom-c5.tar.gz
To recompile the device tree yourself, you can follow the instructions here: Building_kernel_181. Before building the device trees, you'll need to change four lines in arch/arm/boot/dts/socfpga_mitysom5csx_devkit.dts
: either delete or comment out the status = "okay";
lines for the &can0
, &can1
, &hps_lw_bus
, and &gmac1
blocks. I'm also attaching this file with the required changes.

RE: U-boot Error Message - Added by Jose Berlioz almost 3 years ago
Hey Zach,
Thanks for your reply! That worked. I was under the impression I only needed to rebuild the Preloader and U-boot if I changed the HPS.
Thanks for clarifying that.
