Some help from people who are able to test different preloaders is appreciated.
What to do:
Take any preloader from this list and install it to resp. boot media. Note the name of preloader you had used and boot media you placed it to (SD or eMMC).
Boot your board into u-boot, good idea would be to capture bootlog. Go to the u-boot command line. Check bootlog to get an idea what was the real bootmedia u-boot was loaded from. Strings to look for:
“Load u-boot from SD Card...” or “Load u-boot from eMMC...” or “Boot from SD Card!!” or “Boot from eMMC!!”. Note the string you had found.
In u-boot shell execute “md.b 0x00100048 10”, note the output.
Post the info you had noted to this thread so we can collect and analyze it.
Big thanks to contributors in advance!

We should only use the 2 new preloaders (2019-02-22), because they load entire uboot…

Oh my, @sinovoip , it is an epic fail again! Preloaders in files above are bit to bit identical. And if you ungzip BPI-R2-preloader-DDR1600-20190722-2k.img.gz you get a file named BPI-R2-EMMC-boot0-DDR1600-20190722-2k.img - which is exactly what its name implies - BPI-R2-EMMC-boot0-DDR1600-20190722-0k.img prepended with eMMC boot signatures. @sinovoip , why the level of support provided for R2 has to be this bad?

I’d say nope, we shouldn’t. It is OK to use older preloaders as long as u-boot binary size is under 300000.
New preloader behavior w.r.t. boot from eMMC/SD is the same as of BPI-R2-720P-DDR1600-2k.img, i.e.: (1) no “eMMC” string at 0x81dffff0 even when u-boot is loaded from eMMC and (2) it always tries to load u-boot from SD card if any SD card is inserted, no matter the position of hardware boot switch. Point (2) is a show-stopper as it breaks the most useful use case for hw bootswitch. The only point in setting hw switch to eMMC position is to force the board to ignore SD card on boot. Having preloader always trying to load u-boot from SD card no matter what makes it impossible.
P.S. It is especially bad for “board set up at some distant location” case. Forgetting to remove SD card from it will lead to a board hang on the next reboot and user having to drive in there just to eject the SD.

@sinovoip
can you please fix the problems described in preloader?
load uboot from device where preloader was loaded (maybe make real emmc/sd-preloaders which each load specific device), but better would be let 1 preloader look from which device it was loaded
respect boot-switch (can we read out the boot-switch in uboot?)
write a string in memory to determine which device was really used to load uboot
if the prior bootdevice is no more available, try the other one (needs to be only done if a device-switch is done like now or if first 2 points are conflicting). i don’t know which is done by hardware and which by preloader (does hardware/bootrom read-out the boot-switch and load bootloader from the selected device?)

Hi Frank,
I’m trying to create a Debian Buster image from scratch but I’m having hard time to load u-boot.
What is the latest u-boot that works fine ?
I tried to compile u-boot from this repository https://github.com/frank-w/u-boot/tree/2019-10-bpi-r2
Cross compilation on Debian Buster x64 VM is fine and I get an u-boot.bin file (325K in size) then I ran the below commands to write the preloader and compiled u-boot
gunzip -c BPI-R2-HEAD440-0k.img.gz | dd of=/dev/loop8 bs=1024 seek=0
gunzip -c BPI-R2-HEAD1-512b.img.gz | dd of=/dev/loop8 bs=512 seek=1
sudo dd if=BPI-R2-preloader-DDR1600-20191024-2k.img of=/dev/loop8 bs=1024 seek=2
sudo dd if=u-boot.bin of=/dev/loop8 bs=1024 seek=320
For the preloader I used the latest from BPI repository https://github.com/BPI-SINOVOIP/BPI-files/blob/master/SD/100MB/BPI-R2-preloader-DDR1600-20191024-2k.img.gz .
It seems u-boot does not get loaded. These are the last line from the UART boot where is freezes.

You could try using preloader from july…have not tested that from october…only emmc.

The problem seems to be the newer u-boot version 2019-10 release.
I used the preloader from october and compiled u-boot from your default repository (2019-07-bpi-r2 ) and it booted fine.
I have compiled an custom kernel image from your 5.4-main branch but during loading it throws an kernel panic error

You have kernel panic because you have not set root in bootargs or device is not ready…
For uboot i tested all versions till 2020-01 on my buster-sd but have not changed preloader on my sdcard…it is same as in image.

I just run
BPI-R2> printenv
and i see the this line for the bootargs which I think is points to the SD card for the root partition
bootargs=console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait ip=dhcp
Do I need to set the bootargs elsewhere ?
frank-w
December 28, 2019, 10:03am

mmcblk0p2
is mounted but no init found…if you use my 5.4-main, mmcblk0 should be sd-card because of swapped mmc (mainline has emmc=0,sd=1)
https://github.com/frank-w/BPI-R2-4.14/commit/7648f8dc4721a0d2227938f8d2304c067d534969
you have valid rootfs on your sd-card (second partition)?
cioby23
December 28, 2019, 10:10am

I checked now from U-boot console and it seems the filesystem on the second partition is not recognized
BPI-R2> ls mmc 1:2
Unrecognized filesystem type
I ran these 2 commands when I copied the kernel archive into the rootfs but I guess something went wrong
sudo tar -xzf bpi-r2_5.4.2-main.tar.gz -C /mnt/rootfs/boot --strip-components=1 BPI-BOOT
sudo tar -xzf bpi-r2_5.4.2-main.tar.gz -C /mnt/rootfs --strip-components=1 BPI-ROOT

in Uboot mmc is not swapped (as in old bpi uboot). So still 0=emmc and 1=sd.
you can use mmcinfo command after “mmc dev x”
cioby23

Yes EMMC is partition 0 and SD is partition 1

imho you can do this in uboot (if ext4-support is compiled in,maybe without file, but then the list is long
ls mmc 1:2 /sbin/init
ls mmc 1:2 /bin/sh
both files existing on my stretch device (i’m out-of-home so i cannot look on my buster-sd), you can also try listing content of partition without the path…just to check if rootfs is there.
with uboot 2019-10 i have sata-support included which may grow uboot over the size loaded by older preloader…maybe this bug is again in october preloader…just try the july preloader with newer uboot

I followed the short install guide from your wiki page http://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:storage#sd-card step by step but I was not able to make it work.
The only difference I do besides your install guide is manual creation of partitions. I used parted or cfdisk to manually create the partitions.
I see you are importing a partition table using sfdisk from a file.
sudo sfdisk ${loopdev} < ~/Downloads/parttable.dat
I still receive that kernel crash with init not found and the “Unrecognized filesystem type” message when I ran these 2 commands in u-boot console.
ls mmc 1:2 /sbin/init
ls mmc 1:2 /bin/sh
For filesystem type I used vfat (FAT32) for BOOT and ext4 for ROOT. When I mount the SD card to an external Linux PC I see both partitions and the files on them.

where does first partition start? Can you see the initfiles on host pc? Try adding ext4 suport on uboot and look for files there
cioby23
December 30, 2019, 11:23am

I have compiled a new u-boot with ext4 support and after that I do not see the “Unrecognized filesystem type” message anymore.
Now I can see in the u-boot console the content of /sbin and /bin folders from the second partition but the kernel freeze still happens
The /sbin/init and /bin/sh files appear to be symlinks to systemd and dash shell.

Which system do you have on rootfs? Is executable bit set for target binary? how have you created rootfs? Is it right arch?
cioby23
December 30, 2019, 11:35am

I use ext4 on rootfs
BPI-R2> fstype mmc 1:2
ext4
One strange thing is that when I type printenv I see these 2 lines in the output
partition=1:1
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait
Isn’t partition 1:1 mmc and 1:2 sdcard ? Also the root points correctly to partition 2 which is the sdcard.
Sorry I did not understand the question Is executable bit set for target binary?
What do I need to check here ?
