    Hello,
     
    Add latest U-boot support for BPI-R2 & BPI R64 (not yet)
     
    Status:
    I’ve already sent the first round patches for MT7623n,  and the most of the drivers are based on mainline Linux, like clock, timer, mmc, pinctrl, watchdog, power domain and DTS.
     
    I will also upstream U-boot  and ATF for MT7622 (BPI-R64) in the future.
     
    The following are the major differences between Linux and U-boot:
    -Modify the driver interface to adapt the U-boot DM framework.
    -Remove unneeded DT nodes as they don’t have proper drivers in U-boot yet.
    -Just add the basic functions (step-by-step) so that we can monitor the size.
    -Reuse UART driver ns16550.c but add a highspeed register for MediaTek chips.
     
    The current progress for R2:
    -Boot from eMMC or SD card.
    -ROM -> MediaTek preloder -> U-boot -> Linux
     
    Todo list:
    -Ethernet driver
    -Other peripheral drivers.
    -U-boot for MT7622
    -ATF (arm trusted firmware) for MT7622
     
    The patch sets:
    -https://patchwork.ozlabs.org/project/uboot/list/?series=68601
     
    How to build:
    -make mt7623n_bpir2_defconfig; make

    u-boot had to learn bootz and ext commands first.

    Far away from 'automated' but yes boot up isn't much an issue:
    was just a quick and dirty test..  
     
    you can test it on https://github.com/chwe17/build/tree/mt7623 only dev kernel currently tested (btw. the gmac2 patch should be removed it never worked as expected), next is probably broken at the moment..

    The best news is that the final patchset version for HNAT framework was accepted ( kernel 4.16) and it's based on nftables. - https://www.spinics.net/lists/netfilter-devel/msg50973.html

    We will try to add netfilter-base HNAT support for MT7622 & MT7623  in the future.

    a shortly: 
    GbE still sucks and the current network defaults may need some rework anyway (getting it's IP via DHCP doesn't work on firstrun) There are a bunch of generic drivers missing (my el cheapo 2.5'' USB3 enclosure isn't recognized, whereas it's no problem to access it from every other Armbian kernel I use...  after adding some other generic mass storage drivers at least the cheap USB stick gets properly recognized... Anyone a clue what's needed for a 'Innostor IS621' USB-Sata drive to work?  Cause the stick will suck in performance anyway, there's no chance to determine how fast USB is at the moment.. (it get's recognized as SuperSpeed USB but it's a 20$ 64GB noname stick, not worth to test something with it)...  I got fooled by the dev kernel... booted it once just for fun.. Cause debug UART is on UART2, I expected that in bootargs console=ttyS2, actually this was never true for Franks 4.14 Kernel, as soon as you switch to a 'unpatched mainline' (that's what dev is) the console gets silent as soon as ttyS is initialized.  Rebooted probably to early and messed up something so that the FS was corrupted. I could see that setting bootargs to ttyS2 will work but the Image was too much corrupted to bring it up. So we need to patch either franks kernel to the default behavior or patch mainline to franks behavior (I prefer to patch mainline cause I think most other boards will have debug UART on UART0, similar to the reference board, but dev kernel has no priority for me) CPU temperatures aren't accessible yet (probably also a missing module or 'not working' yet). So for anyone want to join the party. USB-UART is a must, not only a 'makes things easier'..

    Hi all,
     
    I tried to share my experience about how to burn preloader/uboot/OpenWRT image, and then boot from eMMC on BPI-R2...
     
    1.Download flash tool from https://spflashtool.com/
    windows: https://spflashtool.com/download/SP_Flash_Tool_v5.1628_Win.zip 
    linux: https://spflashtool.com/download/SP_Flash_Tool_exe_Linux_64Bit_v5.1520.00.100.zip
     
    2. Install MT65xx drivers for your windows PC. You need to install drivers in order to connect your device properlyhttps://spflashtool.com/download/MediaTek_USB_VCOM_drivers.zip
     

    3. Hardware setup before starting up hacking the board
     
      1) use 12v power adaptor
    2) use micro usb to supply extra power when developing on the board that would help reload the images through flash tool (will be introduced in section 4 as the following) just by power off/on to the board manually after images are all selected done.
    3) use console to retrieve the log for debugging purpose
    4) that is wan port
    5) that is lan3 port, so the intermediate ports are listed as lan0, lan1, lan2, and lan3 reviewing from wan port
     
    4.Flash tool configuration
     
      1) download agent: MTK_AllInOne_DA.bin
    2) BPI-R2_OpenWRT_scatter.txt ( https://drive.google.com/open?id=0B6wnb6XNnEQVUXFYWXNUVlFTbnpWVGNPV2NnaEZjX2xjRTZv )
    3) Images
        - Preloader: preloader_iotg7623Np1_emmc.bin ( https://drive.google.com/open?id=0B6wnb6XNnEQVTHZiazNzaGduZVh3VkxBQVRBOFRRYmN1MWt3 )
        - GPT (named MBR here): MBR ( https://drive.google.com/open?id=0B6wnb6XNnEQVcEhDWTJ3NnZ5V3ZiTVlBQl81VkZtRndKeXFJ )
        - Uboot: mt7623_lzma.uboot ( https://drive.google.com/open?id=0B6wnb6XNnEQVVWdDa0FGTGlQUnNWNmg1OENzRkplN1JVeWxV )
        - BOOTIMG: lede-mediatek-32-uImage-mt7623n-bananapi-bpi-r2-initramfs ( https://drive.google.com/open?id=0B6wnb6XNnEQVMXRJV1ZLZkVqYl9td3FlTWR0bERJeEtoRFlZ )
    4) press download button on Flash tool
    5) power off BPI-R2
    6) power on BPI-R2, and then flash tool will update image automatically.
    5 system hang here after upgrading images.
     
      6 try to power off BPI-R2, and on. finally, you can boot from eMMC and see uboot menu. please choose 1 to download OpenWRT FW via TFTP server (e.g., Tftpd64)

    Just enable CONFIG_SND_SOC_MT7623_WM8960, then you can use aplay now...
