Hello,
I bought 2 Bananapi R2 a few months ago. When I plug in and keep the power button pressed, 3 LEDs light up (blue, green, red) and when I release the button they go out. Nothing is displayed on the screen connected via HDMI either. I tried pushing multiple images to an SD card, I have the same behavior. I am a RaspberryPi user and expected to have such an easy time deploying an OS on BananaPi. I want to install Debian 10 or RaspiOS on a SD card and boot from it. Could someone help me?
Thank you,
Ben

Hdmi is available only in linux if hdmi driver is included and your monitor is supporting resolution configured. For debugging problems before hdmi is working you need debug-uart
You can try my [BPI-R2 new image] debian 10 buster image with Kernel 4.19.62
Afair i had included hdmi driver
Make sure your boot switch is in position “1” to boot from sdcard first and press powerbutton at least 10 seconds
in august 2020 i’ve uploaded updated image with newer uboot and kernel 5.4
bpi-r2-buster_5.4.58.img.gz

My BPI R2 still not able to boot using the image.
I try to flash the SD using BalenaEtcher and also dd from a virtual machine with the sd attached to it:
dd if=bpi-r64_debian_stretch_4.19.20.img of=/dev/sdb bs=1M
I can see the partition on the SD :

Hello,
Iptables modules are missing.
For example :
root@bpi-r2:~# modprobe xt_multiport
modprobe: FATAL: Module xt_multiport not found in directory /lib/modules/5.4.58-bpi-r2-main
The package linux-image-armmp contains the modules but it is for another kernel as the one provided for Bananapi R2.
How can I add/install modules for the kernel provided by bananapi ?
Thank you for your help

You can build own kernel from my repo…your current running kernel is from 5.4-main branch,but i have updated it…
Using known steps for building kernel and before building go into menuconfig via
./build.sh config
And enable the module you want, then build and install to sdcard
you try to flash r64 image
I downloaded the right one but not flashed with the right.
