Two cards solution can have AC2600 (4x4ac + 4x4n) concurrent solution, but one card is dual-band only (work at 4x4ac or 4x4n only). In addition, this card is not standard mpcie size, so it’ll cause another pcie slot cannot plug other cards, thanks.
@moore thnx for clarification. Do you know, does other non standard mpcie size wifi card support concurrent wifi solution? And what about this card, do you know anything about it? https://www.aliexpress.com/item/32842242314.html?spm=a2g0o.cart.0.0.6e813c00kSgUC1&mp=1
As far as I know, only Mediatek MT7615D support dual band concurrent feature.i.e., 5Ghz 4x4ac or 2.4Ghz 4x4n => 5Ghz 2x2ac + 2.4Ghz 2x4n, but there is no standard mpcie size MT7615D card and mt76 mac80211 wifi driver cannot support dual-band concurrent mode at this moment.
@moore thnx for clarification, btw, this is a clear statement from asiaRF:
WS3294 each RF connector is with 2.4GHz and 5GHz traces out. MT7615-GAE is with only 2.4GHz out. MT7615-AAE is with only 5.GHz out.
Can you please discuss this in another (new) thread? This is about booting from emmc and not wifi-hardware

@jglanz i tried your way
first i see your working on mmcblk0 (it’s sd-card in my stretch-image, is it diffent in official-images?)
second after i flash the singleimage i see the special-partitions in gdisk:
root@bpi-r64:~# gdisk /dev/mmcblk1

but i can’t add new partition with parted (btw. the commands are for R2)
root@bpi-r64:~# parted -s /dev/mmcblk1 unit MiB mkpart primary fat32 -- 100MiB 356MiB
Error: Both the primary and backup GPT tables are corrupt. Try making a fresh table, and using Parted's rescue feature to recover partitions.
googled a bit around…as p(rint) looks ok, i tried v(eryfy), it shows this:
Command (? for help): v
Problem: The secondary header's self-pointer indicates that it doesn't reside
at the end of the disk. If you've added a disk to a RAID array, use the 'e'
option on the experts' menu to adjust the secondary header's and partition
table's locations.
Problem: GPT claims the disk is larger than it is! (Claimed last usable
sector is 14609966, but backup header is at
1 and disk size is 15269888 sectors.
The 'e' option on the experts' menu will probably fix this problem

then used w(rite) to write the partitiontable again and fix problems
Command (? for help): w

correct this problem? (Y/N): y

OK; writing new GUID partition table (GPT) to /dev/mmcblk1.

now i was able to create the partitions on emmc
root@bpi-r64:~# parted -s /dev/mmcblk1 unit MiB mkpart primary fat32 -- 100MiB 356MiB
root@bpi-r64:~# parted -s /dev/mmcblk1 unit MiB mkpart primary ext2 -- 356MiB 7295MiB
root@bpi-r64:~#
till this point i see emmc-uboot, which i now try to reflash with my emmc/rtl8367-variant…works so far can i clean the openwrt-part anyhow? or can i export the partitiontable and ATF?
i expect that i can dd the first ~1.1MB (uboot is located at 768k and ~300kb in size) or 768k without uboot…atf is before this point (512kb), also the first 4 partitions (tee1,lk,nvram,rf). the 20MB boot-partiton overlaps uboot…maybe thats the cause i can’t mount it
have uploaded both to my gdrive…
https://drive.google.com/open?id=1SRUhYQqs5Jg_lKqgMfUlwSX4dG5T6qPZ
basicly r64_emmc_bootsect*.bin needs to be written to emmc (/dev/mmcblkX) and after reread partitiontable you need to create fs on BPI-BOOT (vfat) and BPI-ROOT
root@bpi-r64:~# partprobe /dev/mmcblk1
root@bpi-r64:~# apt install dosfstools
root@bpi-r64:~# mkfs.vfat /dev/mmcblk1p6 -I -n BPI-BOOT
root@bpi-r64:~# mkfs.ext4 -O ^has_journal -E stride=2,stripe-width=1024 -b 4096 /dev/mmcblk1p7 -L BPI-ROOT
i try to get kernel booted on my machine before create a basic image (without the openwrt-stuff which imho still lays somewhere on my emmc)…
can you tell me whats on the 20MB boot-partition? is this the openwrt-data? which filesystem is it? gdisk says it’s 8300=linux filesystem, but i cannot mount it without mount options
@frank-w the latest boards have mmcblk0 as the eMMC
I’m still prepping an image - you are on the correct track - I actually started using the preloader named forsdcard-0k
I’m pretty close - when I get it locked i’ll update everything - AND YES - u just need the openwrt partition table if you use the preloader u mentioned
@frank-w one more note - mmcblk0boot is where you write the preloader to on the new boards - ONE MORE update - sorry super busy and scatter brained today - you basically want to copy all of the vfat partition + 100MB from the SD - that will include, tee, lk, etc (I used the sector count method you explained in another post)
it’s depend on kernel…i use my own kernel where i swapped mmc to be same as official debian image and r2
preloader has to be written to boot0. with tee/lk,…you mean that i should copy the first 100MB? then i have also the openwrt-stuff still in…
what about boot-partition (is this needed)? if i copy all till there (first2M) i should have all stuff i need, right?
Hello! Could you explain how to not only build kernel BIN-file but also make IMG-file containing all necessary components as u-boot, preload, root.squashfs etc.? So this IMG-file could be written to the SD/MMC.
This topic is for emmc-boot…
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?

@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

maybe emmc-driver is broken in uboot?

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 ?

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:
echo 0 > /sys/block/mmcblk1boot0/force_ro
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:
GPT fdisk (gdisk) version 1.0.1
Caution: invalid main GPT header, but valid backup; regenerating main header
from backup!
Caution! After loading partitions, the CRC doesn't check out!
Warning! Main partition table CRC mismatch! Loaded backup partition table
instead of main partition table!
Warning! One or more CRCs don't match. You should repair the disk!
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: damaged
Found valid MBR and corrupt GPT. Which do you want to use? (Using the
GPT MAY permit recovery of GPT data.)
1 - MBR
2 - GPT
3 - Create blank GPT
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)
