kernel 6.5.4 not loading in Beaglebone black

General Discussion
1

I am giving drive link below, for all boot files I have tried with
https://drive.google.com/drive/folders/1k8KT-YMqi7zHRn50Ba3hMLw9ZNjg0jTz?usp=drive_link

I have used Dowloaded “bone-debian-9.9-lxqt-armhf-2019-08-03-4gb.img.xz” from
Debian 9.9 2019-08-03 4GB SD LXQT - BeagleBoard
first decompressed it as

unxz bone-debian-9.9-lxqt-armhf-2019-08-03-4gb.img

which gives us “bone-debian-9.9-lxqt-armhf-2019-08-03-4gb.img” file
Right click and opening with “Disk Image Mounter” mounted it into

home/waageesh/rootfs

formatted the SDCard again
Using gParted application created 2 partitions again
partion1 is allocated with 512MB memory with filesystem FAT16 and named as “BOOT”
partion2 is allocated with Rest of the memory with filesystem EXT4 and named as “ROOTFS”
Also, labels “boot, lba” are added to partion1 with right clicking on partion1 and choosing “Manage labels”

Post that, I copied all contents from
/home/waageesh/rootfs(rootfs decompressed from beaglebone black image file)
to
/home/waageesh/ROOTFS(parition created in SDCard, which servers as rootfs for kernel while booting on BBB)

Now that I am ready with bootable SDCard, I have inserted it in microSD slot of BBB board
Already changed booting sequence with S2 button earlier, so booting always starts from SDCard(if available any)

Hi @RobertCNelson ,
I really can’t understand why, could you guide more ?

You are using “uenvcmd” in /uEnv.txt… i left this pass in our u-boot builds for end users to do what ‘ever’ they wanted. You are in full control of the boot process…

So since you are in full control, we can not debug what you’ve done.

You need to share your “uEnv.txt” so we can see what you’ve done…

Hi @RobertCNelson
I guess I have already gave link to all files through drive link(BeagleboneBlack_Boot_Files - Google Drive) in previous reply,
but anyway I will uEnv.txt here

uEnv.txt (355 Bytes)

console=ttyS0,115200n8
bootsettings=setenv bootargs console=ttyS0,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait earlyprintk mem=512M

mmcboot=
echo Booting from microSD ...;
echo loadaddr:${loadaddr}, fdtaddr:${fdtaddr};
setenv autoload no ;
load mmc 0:1 ${loadaddr} uImage ;
load mmc 0:1 ${fdtaddr} am335x-boneblack.dtb ;
run bootsettings ;
bootm ${loadaddr} - ${fdtaddr}

uenvcmd=run mmcboot
5

i guess i see that, normally i’m on my phone, i’m not going to click a random link when text works fine…

The key line is:

bootsettings=setenv bootargs console=ttyS0,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait earlyprintk mem=512M

you have console=ttyS0,115200n8 set, so now look at your kernel build, do you have this configured (yes/no)

CONFIG_SERIAL_8250_OMAP=y
CONFIG_SERIAL_8250_OMAP_TTYO_FIXUP=y

earlyprintk doesn’t work that way anymore… since the Board → Device-tree conversion 7-8 years ago, you need to pass the serial address, or make sure the BBB specific kernel config is enabled.

mem=512M why?

Regards,

Hi @RobertCNelson

Those 2 parameters are configured with “y” in .config file, I have checked it.

waageesh@waageesh-Aspire-A715-75G:~/workspace/ldd/source/linux-6.5.4$ grep -inr "CONFIG_SERIAL_8250_OMAP=y" .config 
3109:CONFIG_SERIAL_8250_OMAP=y
waageesh@waageesh-Aspire-A715-75G:~/workspace/ldd/source/linux-6.5.4$ grep -inr "CONFIG_SERIAL_8250_OMAP_TTYO_FIXUP=y" .config 
3110:CONFIG_SERIAL_8250_OMAP_TTYO_FIXUP=y
waageesh@waageesh-Aspire-A715-75G:~/workspace/ldd/source/linux-6.5.4$

Also, I have modified uEnv.txt file as below

bootsettings=setenv bootargs console=ttyS0,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait
mmcboot=echo Booting from microSD ...; setenv autoload no ; load mmc 0:1 ${loadaddr} uImage ; load mmc 0:1 ${fdtaddr} am335x-boneblack.dtb ; run bootsettings ; bootm ${loadaddr} - ${fdtaddr}
uenvcmd=run mmcboot

Tried rebooting again, still it got stuck saying

Yeap it looks fine.

it’s been a long time since i used uImage/bootm, for just try it…

Kernel: make “zImage” target.

Then copy zImage to the same partition as uImage

Then make these changes to uEnv.txt

load mmc 0:1 ${loadaddr} zImage ;

bootz ${loadaddr} - ${fdtaddr}

and see what happens…

Regards,

Hi @RobertCNelson

I tried with zImage and below uEnv.txt file changes

debian@BeagleBone:~$ cat /media/waageesh/BOOT/uEnv.txt
bootsettings=setenv bootargs console=ttyS0,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait
mmcboot=echo Booting from microSD ...; setenv autoload no ; load mmc 0:1 ${loadaddr} zImage ; load mmc 0:1 ${fdtaddr} am335x-boneblack.dtb ; run bootsettings ; bootz ${loadaddr} - ${fdtaddr}
uenvcmd=run mmcboot
debian@BeagleBone:~$

Still kernel is not loading properly

Okay, so no changes… i guess all that’s left… build the kernel with “omap2plus_defconfig” and see any progress, as that will boot…

Regards,

I tried building kernel 6.5.4 with omap2plus_defconfig and copied newly generated below files

  • linux-6.5.4/arch/arm/boot/uImage
  • linux-6.5.4/arch/arm/boot/dts/ti/omap/am335x-boneblack.dtb

to SDCard BOOT partition.

Rebooted the system, this time it is able to load the kernel from uImage of SDCard.
But now, right after kernel is loaded, serious kernel issue occurred as mmc0: Problem switching card into high-speed mode!

Below is the log for the same:

Looks good, it boots up… Now you need to diff your wanted config and omap2plus_defconfig to select what you want and figure out what you misssed… omap2plus_defconfig defaults a lot of options to modules, so you really should install the modules too, or move them to built-in…

Regards,

Hi @RobertCNelson
To be honest,
I really don’t know what should be inside omap2plus_defconfig .
I am just trying to run beaglebone black board UP and running with specific kernel, so that I can start learning device driver programming on ARM architecture.

I just need a minimal setup of BBB board, to make viable for running kernel without throwing any issues.

So there is no problem with micro SD card, isn’t it ?!!!
If so, how should I proceed now ?

13

Since you are running Debian, also change the “rw” → “ro”… in /uEnv.txt … then make sure /etc/fstab on the 2nd partition was updated to use the 2nd partition (default is 1st)… but install the kernel modules and retry…

Regards,

Hi @RobertCNelson
I tried with above changes & still kernel is not booting properly

image
image1845×371 83 KB

But Strangely I have one more observation found.
The rootfs built is for kernel version 4.14.108-ti-r113
whereas kernel is built for version 6.5.4

Doesn kernel of different version won’t work with rootfs built for different kernel ?
But I am very sure, till 1 week back, I have tried with different kernel images(uImage) with same rootfs which I am showing above.

15

still shows ‘rw’, for debian or ubuntu, the base tools really want this ‘ro’…

Correct, the ‘rootfs’ has 4.14.108-ti-r113 pre-installed… But like i said the my previous post, you should install the kernel 6.5.4 modules…

Regards,

16
