One more question to everyone reading this: Could you please allow me to post here right away without “waiting for allowance to post”?!? This is super annoying, thanks!
@jkridner can we get this fixed?
just a thought, did you pull any u-boot config changes form the yocto u-boot build?
interesting,
seems you’re running an older Ubuntu than I, which shouldn’t make any difference, but …
you’re also using a different gcc than yocto, again it shouldn’t make any difference, but …

something else, the u-boot built outside of yocto does not support fastboot upgrade
yotcto build has support for dwc3_gadget, so we need that enabled
i’ll look more at this tomorrow,
So I guess those are the different outputs, when printing version information from the uboot console? Great, so now at least we can be pretty confident, that what I did actually resulted in some working bootable uboot on an SD card! 
Thanks for your work @amf99 ! The next two days I don’t have much time. I will try support afterwards again, especially when I hopefully have a working uart-usb interface again, somewhat in the middle of next week.

Good news, u-boot boot from sdcard resolved,
Thanks to @Kilian for putting us on the right track
using seek in the dd command, was the issue, don't use it

@RobertCNelson now that we got the SD card boot working, may I ask again about the patch from Sipeeed, which may allow to scan for extlinux.conf boot/scanning of sd card? Could this be a possibility to boot uboot from SD card without having to press the button? Do you have a link to the patch? And is there something I could help with to get the patch ported to the BeagleV-Ahead?
Best regards,
Kilian
Great, thanks a lot @amf99 for figuring out what was the problem and finally allowing everyone to boot uboot from SD card! As soon as I have a working uart adapter again, I will test it

ya still working the sdcard thing? the slow response to beagleboard posts, grr.
i’m getting constant reboots with the sdcard inserted and booting from emmc
sdcard is formatted like the emmc, no u-boot or anything else installed on sdcard.
not sure if this posts on beagleboard site, but
one other thing i have seen is system rebooting when doing “git clone” of some sites.
@Kilian @RobertCNelson what happened to the patch from Sipeeed??
is this patch in public domain ??

looks like there is more work to do,
i had zero’d emmc, so it looks like the .bin files are being loaded from emmc.

Hi I managed to boot of the SD card, the only thing using the emmc partition was the uboot part - some sd cards work and some don’t as was posted above. I can share the details if you’re interested. I had to modify the board/thead/light-c910/light.c mentioned in the patch above as well.

Hi @m.zakrzewski you can grab the daily build of the 1.1.2 branch here: Artifacts · BeagleV-Ahead / xuantie-ubuntu · GitLab
Just edit the the “fastboot*” script like so to only update the eMMC partition:
#!/bin/bash
if ! id | grep -q root; then
echo "./fastboot_emmc.sh must be run as root:"
echo "sudo ./fastboot_emmc.sh"
exit
fi
if [ -f boot.ext4.xz ] ; then
unxz -v boot.ext4.xz
fi
if [ -f root.ext4.xz ] ; then
unxz -v root.ext4.xz
fi
fastboot flash ram ./u-boot-with-spl.bin
fastboot reboot
sleep 10
fastboot oem format
fastboot flash uboot ./u-boot-with-spl.bin
fastboot flash boot ./boot.ext4
#fastboot flash root ./root.ext4
fastboot reboot
@RobertCNelson yes I used this repo to build the modified u-boot-with-spl.bin. Ill try if it works with the new kernels and boot/root fs tomorrow with another sd card. I wiped my emmc partition 1 so it looks like using fastboot is limited to uboot in my case anyway
This is the procedure that I used:
Note: the modified uboot always expects the sd card to hold the firmware files
1. Clone the repo
git clone https://github.com/beagleboard/xuantie-ubuntu
cd xuantie-ubuntu
2. Look for the newest CI job’s (e.g. build (#16662) · Jobs · BeagleV-Ahead / xuantie-ubuntu · GitLab) revision to check out
Checking out fd009801 as detached HEAD (ref is beaglev-1.1.2)…
git checkout fd009801
3. Build the images
./01_git_sync.sh
./02_build_opensbi.sh
4. Modify the file:
vim u-boot/board/thead/light-c910/light.c
2260 static void do_firmware_load(void)
2261 {
2262 printf("loading aon...\n");
2263 run_command("if test -e mmc 1:2 light_aon_fpga.bin; then load mmc 1:2 0x10000000 light_aon_fpga.bin; fi; cp.b 0x10000000 0xffffef8000 $filesize", 0);
2264 printf("loading audio...\n");
2265 run_command("if test -e mmc 1:2 light_c906_audio.bin; then load mmc 1:2 0x10000000 light_c906_audio.bin; fi; cp.b 0x10000000 0xffc0000000 $filesize", 0);
2266 printf("loading opensbi...\n");
2267 run_command("if test -e mmc 1:2 fw_dynamic.bin; then load mmc 1:2 0x0 fw_dynamic.bin; fi;", 0);
2268 printf("bootslave..");
2269 run_command("bootslave", 0);
2270 }
The change is from emmc (mmc 0) to sd (mmc 1)
5. Continue building
./03_build_uboot.sh
./04_build_linux.sh
6. Modify the 05_generate_boot.sh file to use sd instead of emmc:
echo "label Linux eMMC" > ./ignore/.boot/extlinux/extlinux.conf
echo " kernel /Image" >> ./ignore/.boot/extlinux/extlinux.conf
-echo " append root=/dev/mmcblk0p3 ro rootfstype=ext4 rootwait console=ttyS0,115200 earlycon clk_ignore_unused net.ifnames=0" >> ./ignore/.boot/extlinux/extlinux.conf
+echo " append root=/dev/mmcblk1p3 rw rootfstype=ext4 rootwait console=ttyS0,115200 earlycon clk_ignore_unused net.ifnames=0" >> ./ignore/.boot/extlinux/extlinux.conf
echo " fdtdir /" >> ./ignore/.boot/extlinux/extlinux.conf
echo " #fdtoverlays /overlays/<file>.dtbo" >> ./ignore/.boot/extlinux/extlinux.conf
sudo ./05_generate_boot.sh
sudo ./06_generate_ubuntu_console_root.sh
7. Write the built uboot:
sudo fastboot flash ram ./u-boot-with-spl.bin
< waiting for any device >
Warning: skip copying ram image avb footer (ram partition size: 0, ram image size: 963464).
Sending 'ram' (940 KB) OKAY [ 0.250s]
Writing 'ram' OKAY [ 0.002s]
Finished. Total time: 0.263s
sudo fastboot reboot
sudo fastboot flash uboot ./u-boot-with-spl.bin
(vertify if the uboot version and build time are new by running the board)
8. Prepare the sd card partitions
sudo fdisk /dev/<sdcard>
press g for new GPT table
n for new partition
p for main partition
make 3 partitions in total, the second one is 200M or more and third e.g. 16G
9. Populate the partitions
cd deploy
sudo mount -o loop,rw boot.ext4 /mnt/temp2
sudo mount /dev/sdc2 /mnt/temp
sudo cp -avr /mnt/temp2/* /mnt/temp
verify if thigs look like this:
sudo vim /mnt/temp/extlinux/extlinux.conf
label Linux eMMC
kernel /Image
append root=/dev/mmcblk1p3 rw rootfstype=ext4 rootwait console=ttyS0,115200 earlycon clk_ignore_unused net.ifnames=0
fdtdir /
fdt /th1520-beaglev-ahead.dtb
sudo umount /mnt/temp
sudo umount /mnt/temp2
sync
sudo mount -o loop,rw root.ext4 /mnt/temp2
sudo mount /dev/sdc3 /mnt/temp
sudo cp -avr /mnt/temp2/* /mnt/temp
sudo umount /mnt/temp
sudo umount /mnt/temp2
sync
Alternatively: (not sure if this does not corrupt the fs on the sd card)
sudo dd if=boot.ext4 of=/dev/sdc2 status=progress
sudo dd if=root.ext4 of=/dev/sdc3 status=progress
sync
sudo eject /dev/sdc
- Insert the sd card into beaglev ahead and reset/power on
Also edit /etc/fstab to use mmcblk1 - I think it’s ok to do it on the beaglev itself
Could someone reproduce please?

I tried to follow your instructions, here’s a few comments
what is partition #1 size ?
“p for main partition”, p prints, not sure what you want
partition #2 and 3 need to be formated, mkfs.ext4
run ‘sync’ before ‘umount’ of mounted devices
extlinux.conf is missing,
fdt /th1520-beaglev-ahead.dtb
7. Write the built uboot:
should this be done after the sdcard has been inserted into the board ??
the following is after reboot (the time stamp looks correct)

Hi @amf99 thank you for the remarks, here is the amended procedure, tested with the original yocto, original ubuntu, and the ubuntu console and ubuntu xfce rootfs images:
Note: the modified uboot always expects the sd card to hold the firmware files
1. Clone the repo
git clone https://github.com/beagleboard/xuantie-ubuntu
cd xuantie-ubuntu
2. Look for the newest CI job’s (e.g. build (#16662) · Jobs · BeagleV-Ahead / xuantie-ubuntu · GitLab) revision to check out
Checking out fd009801 as detached HEAD (ref is beaglev-1.1.2)…
git checkout fd009801
3. Build the images
./01_git_sync.sh
./02_build_opensbi.sh
4. Modify the file:
vim u-boot/board/thead/light-c910/light.c
2260 static void do_firmware_load(void)
2261 {
2262 printf("loading aon...\n");
2263 run_command("if test -e mmc 1:2 light_aon_fpga.bin; then load mmc 1:2 0x10000000 light_aon_fpga.bin; fi; cp.b 0x10000000 0xffffef8000 $filesize", 0);

2266 printf("loading opensbi...\n");
2267 run_command("if test -e mmc 1:2 fw_dynamic.bin; then load mmc 1:2 0x0 fw_dynamic.bin; fi;", 0);
2268 printf("bootslave..");
2269 run_command("bootslave", 0);
2270 }
The change is from emmc (mmc 0) to sd (mmc 1)
5. Continue building
./03_build_uboot.sh
./04_build_linux.sh
6. Modify the 05_generate_boot.sh file to use sd instead of emmc:
echo "label Linux eMMC" > ./ignore/.boot/extlinux/extlinux.conf
echo " kernel /Image" >> ./ignore/.boot/extlinux/extlinux.conf

echo " #fdtoverlays /overlays/<file>.dtbo" >> ./ignore/.boot/extlinux/extlinux.conf
sudo ./05_generate_boot.sh
sudo ./06_generate_ubuntu_console_root.sh
7. Write the built uboot:
Warning: the sd card should not be inserted during uboot writing, and it is safer to power down the device before inserting the sd card, because of some repartitioning done to mmc apparently, maybe by the uboot put into RAM
sudo fastboot flash ram ./u-boot-with-spl.bin
< waiting for any device >
Warning: skip copying ram image avb footer (ram partition size: 0, ram image size: 963464).
Sending 'ram' (940 KB) OKAY [ 0.250s]

Finished. Total time: 0.263s
sudo fastboot reboot
sudo fastboot flash uboot ./u-boot-with-spl.bin
(vertify if the uboot version and build time are new by running the board)
8. Prepare the sd card partitions
sudo fdisk /dev/<sdcard>
press g for new GPT table
n for new partition
1 for first partition etc.
make 3 partitions in total, the first can be any size, second one is 200M (boot partition) or more and third e.g. 16G or the rest of card’s capacity (root partition)
/dev/<sdcardp1> 2048 22527 20480 10M Linux - system plików
/dev/<sdcardp2> 22528 636927 614400 300M Linux - system plików
/dev/<sdcardp3> 636928 489060351 488423424 232,9G Linux - system plików
Partition types should be 20 Linux filesystem 0FC63DAF-8483-4772-8E79-3D69D8477DE4
which is the default in fdisk
Create the ext4 filesystem on those partitions:
sudo mkfs.ext4 /dev/<sdcardp1>
sudo mkfs.ext4 /dev/<sdcardp2>
sudo mkfs.ext4 /dev/<sdcardp3>
9. Populate the partitions
cd deploy
sudo mount -o loop,rw boot.ext4 /mnt/temp2
sudo mount /dev/<sdcardp2> /mnt/temp
sudo cp -avr /mnt/temp2/* /mnt/temp
verify if thigs look like this:
sudo vim /mnt/temp/extlinux/extlinux.conf

sudo mount /dev/<sdcardp3> /mnt/temp
sudo cp -avr /mnt/temp2/* /mnt/temp
sync
sudo umount /mnt/temp
sudo umount /mnt/temp2
sync
Alternatively: (not sure if this does not corrupt the fs on the sd card)
sudo dd if=boot.ext4 of=/dev/sdc2 status=progress
sudo dd if=root.ext4 of=/dev/sdc3 status=progress
sync
sudo eject /dev/sdc
Note: Due to the writing to sd card which was inserted multiple times sometimes has no effect, be sure to check if the writing indeed occured, see: image - DD claiming to write to SD card, not doing anything - Raspberry Pi Stack Exchange
I had the same problem. In addition, I found out that removing the old partitions on the SD card using
fdiskdid not do anything either, which is a quicker test than tryingddagain. I was able to create a file usingtouch this_is_partXin the root of each mounted partition on the SD card, which is useful to check 1) if the SD card is still functional and writeable, and 2) if a subsequent reinstall of the pi image actually worked and overwrote these files. The fix turned out to reboot the linux pc used for installing the image to the SD card. After the reboot, theddcommand took about twice the time, and really wrote a fresh image on the SD card.
10. Insert the sd card into beaglev ahead and reset/power on
Also edit /etc/fstab to use mmcblk1 - I think it’s ok to do it on the beaglev itself
Still not working,
the u-boot is the correct one, being it was built this morning.
also zero’d out the emmc, just to make sure.

Looks like sd card problem. Did you try on a different sd card? Also did you verify that writing the sdcard was 100% finished before you took it out the pc?
For better reproducing your conditions I also zeroed my emmc but it still works.

At this point I am quite convinced that it works, especially after zeroing the whole emmc, so maybe try with other sd cards and be strict about making sure that the sd card writing went 100% ok.
