@moore : do you have some benchmark of this 5Ghz Wifi card? Can it do 80-90MB/s
Can you please discuss this in another thread because it is off-topic?
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>

BPI-R64>
@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
root@bpi-r64:~# ./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 
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 wrote them this way to emmc:

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)

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)

r64-uboot-emmc.patch (2,1 KB) for patching my bpi-r64 branch
@ray can you please decode the binary uploaded here: https://drive.google.com/open?id=1rLtG_nwjnfrbO0iXg0ezeB9SipUYk1fl to the crash-location
personal debugger? 
if you can say me how to do it by myself 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
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:
