Bpi-r64 quick start (boot from eMMC)

tried accessing emmc with own uboot and got this:

seems uboot cannot read gpt-partition table…@jglanz have you an idea? tried also setting CONFIG_EFI_PARTITION in mt7622_evb.h in emmc-block without success (to test for efi/gpt-partitions)

also tried to enable CMD_GPT, which also fails because of missing define

 #error CONFIG_PARTITION_UUIDS must be enabled for CONFIG_CMD_GPT to be enabled

seems like i need to only define it without value…but how to handle it?

BPI-R64> gpt
gpt - GUID Partition Table

Usage:
gpt <command> <interface> <dev> <partitions_list>
 - GUID partition table restoration
 Restore GPT information on a device connected
 to interface

@Jackzeng @sinovoip have you anywhere a emmc-preloader for r64 which can handle mbr or can guide me to get gpt working in uboot?

maybe uboot looks on wrong hw-partitions? it needs to look on the user-partitions and not e.g. boot0

how can i define that?

i also used mmc-utils to verify PARTCONF

[email protected]:~# ./mmc extcsd read /dev/mmcblk1 | grep PARTITION_CONFIG                                                                                              
Boot configuration bytes [PARTITION_CONFIG: 0x48]

maybe emmc-driver is broken in uboot?

looks strange

Found this:

as it is in “normal” linux-kernel-repo i guess it is working for ubuntu/debian-images. i made a diff and it’s not the same preloader as above…

currently flashing official debian to my emmc :wink:

unfortunately offical uboot from debian-image prints similar errors on trying to access emmc. played also a bit with switch near reset which seems to be the mmc-selection-switch, results are the same

it seems that uboot always access the same mmc-device (regardless i add device-number 0/1). if i insert sd-card i can show mmc1 (also if requested mmc0), but if i remove sd-card i cannot access both

also if i boot from emmc (till uboot) and try to boot from sdcard (the one acessable) kernel gets loaded, but boot hangs after ATF

@sinovoip @Jackzeng can you help us getting emmc working with debian/ubuntu?

Both 4.4 kernel and 4.19 have been updated to support eMMC startup, please re-burn preloader

please see this log:

Sd card preloader version number is different from emmc version number

I used preloader from my last post (changed/uploaded also on oct 2nd) and official debian buster

Maybe i need to replace uboot with emmc-version to get emmc-driver buildin?

Have you changed anything there i have not yet in bpi-r64 uboot ?

emmc preloader version number : [BLDR] Build Time: 20190927-141930

You can use this option way to take TFTP burn just use we preloader,Because we talent supports both GPT and msdos partition formats

ok here complete bootlog (same buildtime of preloader in boot0-block)

used this preloader: https://github.com/BPI-SINOVOIP/BPI-R64-BSP/blob/95b2edeed3a54529b0cf8598d52a2badd2069c8a/mt-pack/mtk/bpi-r64/configs/default/linux/preloader_evb7622_64_foremmc.bin

and this image: 2019-08-23-debian-10-buster-lite-preview-bpi-r64-sd-emmc.img from here: BPI-R64 Ubuntu 16.04 & AArch64 Linux Lite & Debian 10 Buster Lite Demo Images Release 2019-08-23

And wrote them this way to emmc:

dd if=preloader_evb7622_64_foremmc.bin of=/dev/mmcblk1boot0
unzip -p 2019-08-23-debian-10-buster-lite-preview-bpi-r64-sd-emmc.img.zip | dd of=/dev/mmcblk1 bs=1M

from sd-boot i get this when starting gdisk for emmc:

Your answer:

hi, i see also the raise errors and unknown partitiontable (where i do not know if it is from sd or emmc)

mmc-part of preloader-output looks same as in your log

also i see you have a newer build of uboot (not the one from the ubuntu-image)

U-Boot  (Oct 02 2019 - 15:01:05)

and you use a ubuntu 18.4 image i have not found yet (only 16.4 for r64). also in your wiki there is only ubuntu 16.4.

i guess you have changes in uboot/image (atf, bootheaders, …) which are not yet public

tried to fix emmc-boot like it’s done here:

using id instead of fixed “1”, but this leads to uboot-crash (maybe unaligned access)

@ray can you please decode the binary uploaded here: https://drive.google.com/open?id=1rLtG_nwjnfrbO0iXg0ezeB9SipUYk1fl to the crash-location

personal debugger? :slight_smile:

:stuck_out_tongue: if you can say me how to do it by myself :wink: but it seems that linaro objdump does not work like yours

objdump in that case

objdump -d u-boot > u-boot.asm

you’re right…i meant objdump…

arg…it looks like i have missed patching mmcinfo-helper-function itself (only changed forward declaration)

That works for the normal OpenWrt build. But if the OpenWrt included many third-party modules, the initramfs-kernel.bin may bigger than 20MB+, after load that kernel into flash via TFTP, the kernel decompress failed with error “Uncompressing Kernel Image … LZMA: uncompress or overwrite error 1”. I think it’s the kernel partition is too small to fit the big kernel. But i don’t know how to modify the kernel partition size. Could you please tell me how to?

Have a nice day! Is there a fresh working firmware assembly OpenWrt/LEDE?

Hi all,

I tried to boot from eMMC but failed. Neither using U-Boot Menu nor explicit commands

echo 0 > /sys/block/mmcblk0boot0/force_ro
dd if=preloader_evb7622_64_foremmc.bin of=/dev/mmcblk0boot0

from https://github.com/BPI-SINOVOIP/BPI-R64-BSP/blob/95b2edeed3a54529b0cf8598d52a2badd2069c8a/mt-pack/mtk/bpi-r64/configs/default/linux/preloader_evb7622_64_foremmc.bin

helped. I always get

System halt!

What is the problem?

I successfully boot from SD. Also, I managed to change root partition in uEnv.txt file to eMMC’ one and load system from eMMC, but not the kernel.

I many times toggled Boot select switch (physical), but not understand how it works. It seems it doesn’t work with my BPI-R64, that is I got boot from SD in either cases and cannot boot anyhow without it.

That means that preloader does not get loaded…only bootrom.

You have executed the 2 lines from system booted by sdcard? Any error-message?

No, no errors. The output:

tried bootswitch? in 0-position? make sure it snaps into position…

bootswitch selects first boot-device

Tried both, no success. What really should do that switch in position 0 and what in position 1?

mhm, position 0 is booting emmc first

can you look with mmc-tools about your partition-config?

it should be 0x48
