Hi All,

  I updated one of my two RK3288 boards (Viewsonic) with newer Android
factory firmware (using Windows) and now it won't boot mainline u-boot
when I use the same exact recipe that worked previously:

sudo ${UPGD} db rkbin/rk32/rk3288_boot.bin
sudo ${UPGD} wl 0x40 tftpboot/u-boot-dtb.bin

  Been trying to figure out what's wrong.  My theory is that the newer
firmware enabled one of the "boot areas" of the eMMC and the "wl 0x40"
command above only writes to the user area of the eMMC.

  I can still load and run one of the Android u-boots using the
boot_merger method:

./tools/boot_merger --subfix ".10.bin" ./tools/rk_tools/RKBOOT/RK3288.ini

  then flashing via:

sudo ${UPGD} ul u-boot-android/RK3288UbootLoader_V2.30.10.bin

  But these u-boot's are virtually useless since they striped of
useful commands (like mmc commands).

  I tried using the above boot_merger command on mainline u-boot but
it only boots this far (I've tried u-boot-dtb.bin and u-boot.bin):

--------------------------
U-Boot 2016.11-08467-g05b8ba7-dirty (Jan 15 2017 - 10:40:37 -0800)

Model: SCT36-RK3288
DRAM:  128 MiB
--------------------------

  Note the incorrect DRAM size.  My normal boot looks like:

--------------------------
U-Boot SPL 2016.11-08467-g05b8ba7-dirty (Dec 18 2016 - 11:00:14)

U-Boot 2016.11-08467-g05b8ba7-dirty (Dec 18 2016 - 11:00:14 -0800)

Model: SCT36-RK3288
DRAM:  2 GiB
MMC:   dwmmc at ff0c0000: 0, dwmmc at ff0f0000: 1
...
--------------------------

  Note that this runs SPL, then normal u-boot whereas the previous one
didn't run SPL.

  Any ideas how I can get mainline u-boot running on this board?

  Thanks much,

  Rick

Hi Kever and Simon,

  Thanks very much for the help.  Really appreciate it.

  I'm using this method:

  See below for the output.  I noticed that I only have "Channel b"
and not "Channel a".  On my other board that boots, I have both a and b. I
wonder if one bank of DDR3 went bad on this
board.  What do you think?

  Thanks again.

  Rick
