Having received BPi-W2 I tried the images with the legacy
root@bpi-iot-ros-ai:~# cat /proc/version
Linux version 4.9.119-BPI-W2-Kernel (root@bpi-iot-ros-ai) (gcc version 7.3.1 20180425 [linaro-7.3-2018.05 revision d29120a424ecfbc167ef90065c0eeb7f91977701] (Linaro GCC 7.3-2018.05) ) #4 SMP PREEMPT Mon Apr 29 15:13:32 CST 2019
I was stuck on the final stage of

How to update both u-boot and Linux kernel
I plugged into the host USB my SD Card with the Debian image for W2 in order to update u-boot and Linux kernel. The SD Card appears on the host system as :
STORAGE_DEVICE sdb disk 60G
├─sdb1 part vfat 256M BPI-BOOT
└─sdb2 part ext4 6.8G BPI-ROOT
Accessing the docker “optimistic_nash” instance with --privileged=true :
root@deb10:~# docker exec -it --privileged=true optimistic_nash /bin/bash
executes without errors.
access to external SD Card has finally been resolved by creating an identical container :
root@deb10:~# docker commit optimistic_nash mybpi-buildimage
and then running it with --privileged :
root@deb10:~# docker run -it --privileged mybpi-buildimage bash
Now the problem comes after building the kernel from the sources.
The build runs successfully :
Please choose a mode(1-7): 1
The SD directory contains necessary files :
BPI-W2-bsp/SD# ls -al bpi-w2/ 100MB/ BPI-BOOT/ linux-headers-4.9.119-BPI-W2-Kernel.tgz
I plug my SD Card with the previously written image to it, which I want to update with the newly built kernel. The card is well identified by the system as /dev/sdb
Anyway, the following command doesn’t update the kernel on the target SD Card with the image :
BPI-W2-bsp/SD# bpi-update -c bpi-w2.conf -d /dev/sdb
What am I missing?
Alternatively, what is a manual kernel update procedure on the the target image?
SINOVOIP doesn’t make the task easier with poor basic tasks documentation.
Obscure bpi-update bpi-bootsel may be helpful for the well tested systems, but would rather become an obstacle when deploying new systems, which the BPi-W2 is. Probably a more detailed custom kernel and u-boot deployment document is necessary.
I’ve tried several kernel branches for now: mainline, next, legacy BPI-SINOVOIP. In the absence of Realtek’s support, accessibility to the board features is very poor. Even basic ethernet NIC’s are not operational, even with the legacy BPI-SINOVOIP, which is supposed meeting this basic task. I do not even mention the video Mali T820 support, which is probably far from being thought of.
I think sending the card back to supplier, as it can not be used the goal it is sold for. Even worse, I can hardly imagine any application it can be used for in the current state.
