Beagleboard X15 RevB1 booting issue

I am having some problems booting the new code on the Beagleboard X15 Rev B1 with a micro SD card. So far for dev I have been using the Rev 3 that comes with the TI EVM. We use the board with our own LCD board for a demo to the customer while we are waiting for our own board that uses an automotive part.We need to send a couple demo to a customer.

Not wanting to pay the $600 for the full dev since we remove the 7 inch LCD display, we bought a couple of Beagleboard X15 Rev B1. It turns out that the new code from TI will not boot from it. This tells me that the code was written but never tested on the actual hardware.

Before it hangs it shows this :

[ 2.368521] No soundcards found.
[ 2.372846] Waiting for root device PARTUUID=000c9edb-02...
[ 119.798818] random: nonblocking pool is initialized

On the Beagleboards Rev A2 and A2 it works perfectly.

[    2.521810]   No soundcards found.
[    2.728877] EXT4-fs (mmcblk0p2): recovery complete
[    2.740066] EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)
[    2.748212] VFS: Mounted root (ext4 filesystem) on device 179:2.

I did several experiments

I tried the older u-boot. It works fine except that it doesn't recognize the HDMI correct frequency and runs in some low resolution. That is because it loads the wrong device tree, there has been a GPIO change there. If I create a link to force loading of the B1 devicetree I get identical results as with the newer u-boot

I tried the u-boot that Robert Nelson did to fix the problem for his debian. It gives me several bad partitions error messages, amusing considering that I only have two partitions. It then boots debian which is on the eMMC. I even tried his patch for the kernel, still using TI kernel.

This morning I recreated two images, one with the SPL and u-boot written in raw mode and the other with the files copied on a FAT partition.

For the one in raw mode I get a bad 2nd partition which is weird considering that there is only one partition in the case.

In my recording I have the 3 listing, I stopped the listing for the one that works after it shows that it found the ext4 partition

I posted on google since I figured that it is not TI hardware and that I might get a quicker answer. Robert told me that since it is TI SDK it would be better to describe the problem here.

The difference between the two hardware don't seem to be that big so I am confused as to why I have this weird issue.

If you take a look at the AM57x Linux SDK download page (software-dl.ti.com/.../index_FDS.html) you will see that supported EVMs are: AM572x EVM (TMDSEVM572X), AM572x IDK (TMDXIDK5728), and AM571x IDK (TMDXIDK5718).

Beagleboard X15 is not a TI design. It's a community project, developed and supported by www.beagleboard.org The AM572x GP EVM processor boards are similar to it, but not identical.

I understand your point but that is an unacceptable answer if Texas Instruments is serious about wanting us to go to production with their DRA devices. I checked on the google group and was told that I would get a better answer here. No matter what your disclaimer says, you have the B1 version supported in your SDK and it is broken. I think that the disclaimer was added because you couldn't figure out where the bugs were. The beagleboard X15 board was supported prior to the B1 fix to pass FCC.

I need to get those two boards working for our demo to a customer since we have a small delay on our DRA726 board prototypes.

What is the processor you are using? Is it DRA726? please confirm.

0 Michel Catudal over 8 years ago in reply to Rogerio Almeida

Genius 3825 points

Our design uses a DRA726 but the two panels that I am working on as a demo for the customer use the BeagleBoard X15. I have a few EVM but we want to keep those here for development. We have a custom LCD 12 inch board which we are making an adapter for the Beagleboard X15. This will give use some time to get our hardware finalized.

If you need more details we need to discuss that as part of our NDA, not on a public forum.

Last night I fixed the bug in TI Linux kernel for the Beagleboard A15 RevB1. For some mysterious reason support for the micro SD was removed in the device tree. This explained why it booted with the older kernel which could not identify the board as the RevB1. What was puzzling was the fact that u-boot could recognize the disk but then after it loaded the kernel the disk was no longer recognized. Once I realized that I looked deeper and realized where the problem was.

One thing that surprised me was that the command line display now works for the full screen and weston didn't crash.Maybe it was just a higher quality HDMI monitor I have at home. I will test at work this morning on a couple of monitors, one HDMI and one DVI.

I will have to do many power cycles to be sure that it was not just luck on that particular board.

I still have the weston crash problem on the DVI monitor (I use an HDMI to DVI adapter). The full screen command line display works. I only cycle the power 4 times on when it was connected to the ASUS hdmi monitor so that may just have been luck. On the DVI monitor weston crashed on the first boot.

It works fine if I restart the weston service. I haven't tried shutting off the HDMI monitor as I did on my beaglebone at home. In that case after a while weston crashed.

This board behaves somewhat better than the TI Rev3 but that may just be luck. I do have another board from TI that doesn't seem to have problems. That one is connected to a 7 inch LCD display. I have 2 other boards that have the weston issue both Rev 3. My Rev 2 board has the issue as well. The issue is present for both LCD board and HDMI.

Michel,

Due to the fact that TI does not control the Beagleboard-X15 hardware and because it has diverged from our EVM, removed it from our officially supported hardware list as of Proc SDK 3.00. Note, however, that there is still a tremendous amount of community support for this board. For example, I had a look at the mainline kernel and I see there are updates that have been merged to support the new Rev B1 board:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts?id=refs/tags/v4.9-rc2

You'll see that there's now a file called am57xx-beagle-x15-revb1.dts at the link above. I recommend verifying your changes against it so you can be sure you didn't miss anything.

Best regards,
Brad

Brad,

Good to know. I seem to have less display problems with the Beagleboard X15 RevB1 than on the Rev 3 from TI. I don't know if it is related to the same thing that creates an issue with FCC tests. What I was told was that in order to pass FCC they had to remove the current sensing hardware that TI had.

I know that the community had issues with booting on emmc. My main issue with the TI board has to do with the weston crashes. One thing I did notice on that was that on the first boot after I had created an image it would calibrate the touch screen, weston never crashed in that condition. Perhaps all that is needed is a small delay on starting the weston service. Shutting off the HDMI monitor also crashes weston.

I won't know if the crashing issue will exist on our 12 inch LCD displays until we get them. I do know that it crashes on the TI 7 inch display with the TI boards. My first impression with the B1 board last night and this morning was that the problem won't be there for our B1 board but after I connected one board to Tom's monitor I realized that the problem is still there. The community and TI board are very similar.

We can get around the problem for now but that has to be resolved before the middle of next month.

I have a Rev A2 version of the X15 and I am trying to get a Yocto build up and running.
I am having some issue with getting it booting off of an SD card and I am think that it is my uEnv.txt.
It has been hard trying to find examples what should be in the uEnv.txt.

Currently it will load the dtb and the zImage but when it executes the kernel it just hangs. I have taken other kernels from different images and it looks up in the same place. Any examples of what you guys used for the uEnv.txt would be great.

Thanks,
Seth King

I'm using the file that ships in the SDK at /ti-processor-sdk-linux-am57xx-evm-03.01.00.06/board-support/prebuilt-images/uEnv.txt. It's empty though:

# This uEnv.txt file can contain additional environment settings that you
# want to set in U-Boot at boot time. This can be simple variables such
# as the serverip or custom variables. The format of this file is:
# variable=value
# NOTE: This file will be evaluated after the bootcmd is run and the
# bootcmd must be set to load this file if it exists (this is the
# default on all newer U-Boot images. This also means that some
# variables such as bootdelay cannot be changed by this file since
# it is not evaluated until the bootcmd is run.

I recommend reverting back to the binaries from the SDK and then substituting your components one at a time: MLO, u-boot.img, zImage, dtb, etc.

I have figured out how to boot on the micro SD card on the B1 version. TI has the support for the micro SD card removed for that revision but not for Rev2 so I am not sure why you can't boot on Rev 2.

At work I have Rev A3 and Rev B1. I have Rev 2 at home and I have no problem booting off the micro SD card. Do you have a fat partition on your micro SD card?.

If you are trying to boot with 1 ext3 or ext4 partition that won't work with TI's u-boot which requires a fat partition for MLO and u-boot.img

The u-boot from eewiki doesn't work with the micro SD card. I think their u-boot only works with the emmc.

It looks for the EEPROM identification of the board and will read the device tree of the rootfs partition on the boot directory.

The u-boot that comes with the yocto package doesn't support booting off the first partition, it is hardcoded to boot of the second partition.

I have modified u-boot to boot off an ext4 partition. I do not have any fat partition, the only partition I create is an ext4 partition and MLO and u-boot.img are programmed in raw mode.

On my system I have one disk of 4TB where I have gentoo and one 2TB where I have Debian. So my micro SD card is on /dev/sdc

dd if=MLO of=/dev/sdc count=1 seek=1 bs=128k
dd if=u-boot.img of=/dev/sdc count=2 seek=1 bs=384k

for u-boot edit the file "include/configs/ti_omap5_common.h"

Change the 2 for a 1 (in red)

#define CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG
#define CONFIG_EXTRA_ENV_SETTINGS \
        DEFAULT_LINUX_BOOT_ENV \
        DEFAULT_MMC_TI_ARGS \

        "fdtfile=undefined\0" \
        "bootpart=0:2\0" \

                "echo Boot fastboot requested, resetting dofastboot ...;" \
                "setenv dofastboot 0; saveenv;" \
                "echo Booting into fastboot ...; fastboot 0;" \
        "fi;" \
        "run findfdt; " \
        "run envboot; " \
        "run mmcboot;" \
        "setenv mmcdev 1; " \
        "setenv bootpart 1:2; " \
        "setenv mmcroot /dev/mmcblk0p2 rw; " \
        "run mmcboot;" \
        ""

I haven't checked to see if yocto build would boot, I just use it with my misc OS.

I have created so far

1-Funtoo

2-Fedora 24

3-SuSE

4-Arch Linux

I will publish funtoo on my suzielinux.com website in the new two or three weeks.

I need to finish the creation of Lazarus first which I will do tomorrow and then I check to make sure the video and sound works correctly.

The other ones are just minimal systems with no GUI yet, I will start with Arch Linux and then do the other two.

So I am using 2 partitions and I am 99% confident that the MLO and uboot are working because the build date of the uboot is the same day that I did my yocto build. Additionally uboot can find and load both my dtb and zImage so I think that part is working correctly.

So if you are booting from the SD card does it change how the devices are enumerated? I have debian on the eMMC and I can put the SD card in after it boots up and the eMMC is /dev/mmcblk0 and the SD Card is /dev/mmcblk1. I figured this would stay the same not matter which device you are booting from. So I made my root directory /dev/mmcblk1p2, when attempting to boot from the SD card.

What does changing bootpart from 0:2 to 1:2 do specifically?(I tested this change this morning and if I put 1:2 in then it craps out to uboot because of Invalid partition 2)

Thanks for the help,

Seth

0 Neuromancer2701 over 8 years ago in reply to Neuromancer2701

I got it booting. It was the rootfs path root directory /dev/mmcblk1p2 once I changed it to root directory /dev/mmcblk0p2 the LEDs started blinking then I figured out it was console path too.

I played around with this too and I got confused on the working. I need to read a bit more to really understand what is going on. It seems that when you have both devices on power up the devices are switched. I tried Robert Nelson's u-boot but I was not able to get it to boot on the micro SD card. He told me that he could not boot from emmc with TI's u-boot. That is when I started to play with u-boot and realized that it would only boot with a fat partition and the rootfs on the second partition.
After a few crashes during my tests at work I realized that the fat partition was a problem. Sometimes it would not boot until I clear the dirty flag on it. Anyhow I fail to see the logic in using a fat partition on a linux system.

Robert has a different reason than me for that, he said that the reason he was not using the fat partition was because people tend to delete or mess with MLO and u-boot.img and then complain why it doesn't boot.

Good to know that you got your u-boot to work. On my comments about my misc OS, I will publish something on my suzielinux.com web site either the coming weekend or next. I have funtoo working with mate desktop using Vivante 2D GPU and am in the process of creating packages for archlinux. When that is done I will publish both and minimal versions of Fedora 24 and OpenSuSE. The only problem I have with SuSE right now is that it doesn't seem to like that I do not use a SuSE generated kernel. It does work fine though except for the systemd error message.
