Connect 4G module and RJ45 with R2 board，I used pppd to dial up R2 successfully，Logs are following：

But after I plugged out RJ45 from my R2 board，I failed to download speedtest-cli tool，and ping www.baidu.com failed， Logs are following：

added that to mt7623.dtsi

	uart0: serial@11002000 {
		compatible = "mediatek,mt7623-uart",
			     "mediatek,mt6577-uart";
		reg = <0 0x11002000 0 0x400>;

following devices are detected during boot (pins by schematics):

pin 8/10 = uart1 (tx/rx) = 11003000 = ttyS2
pin 11/13 = uart0 (tx/rx) = 11002000 = ttyS1

now i'm connected an arduino (sends keepalives and sending back "AT-Strings" it receives (tested with RPI)) to uart1 and trying to access:

#!/bin/bash
DEV=/dev/ttyS2
while read line; do
  echo "["$(date "+%Y-%m-%d %H:%M:%S")"] received: "$line
done < <(cat $DEV)

i can see the keepalives, but when i try to send data:
echo "AT" >/dev/ttyS2
nothing happens (arduino send AT back if it receives it), so BPI-R2 does not send it

serial on arduino is configured with
Serial.begin(9600);

on BPI-R2:

stty -F /dev/ttyS2 -a

I'm trying to install wireguard on the Banana PI R2 running Ubuntu 16.04, latest image.

However, on the installation, I'm getting an error that reads:

dpkg: warning: version '*-*' has bad syntax: version number does not start with digit
It is likely that 4.4.70-BPI-R2-Kernel belongs to a chroot's host
Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed.

There is an workaround, not Banana PI related, here: openzfs/zfs#1260

However, as the kernels are not provided by default repositories, I can't install this generic kernel.

Any help on this is appreciate. Thanks

Hi,

I wanted to change a little bit the configuration of the kernel so that i can use a camera with my BPI-R2.

My setup is particular since i use a grabber (the Magewell USB Capture HDMI Gen 2) and a camera plugged in hdmi to this grabber. Finally the camera should be seen as an usb camera device.

The setup is working on my ubuntu 16.04 (kernel 4.13.0-39-generic), i use uvc and v4l and i can display the camera flux using qv4l2 for example.

I tried to configure the kernel so that i have the same modules i use on my desktop version. To do so i had to configure MEDIA_CAMERA_SUPPORT = y, MEDIA_USB_SUPPORT = y and USB_VIDEO_CLASS = m.

The list of module i need :

Module Size Used by
snd_usb_audio 196608 1
snd_usbmidi_lib 32768 1 snd_usb_audio
uvcvideo 90112 0
videobuf2_vmalloc 16384 1 uvcvideo
videobuf2_memops 16384 1 videobuf2_vmalloc
videobuf2_v4l2 24576 1 uvcvideo
videobuf2_core 40960 2 uvcvideo,videobuf2_v4l2

videodev 176128 3 uvcvideo,videobuf2_core,videobuf2_v4l2
media 40960 2 uvcvideo,videodev

The two module i'm missing are media.ko and videodev.ko but when i set MEDIA_SUPPORT = m , i got the following error at the compilation (see attached file). I don't understand this error because i found the definition of the functions marked as undefined references in linux-mt/include/media/cec.h.

I don't know if i'm missing dependencies or if it's a bug because i'm pretty new to that stuff, a little help would be appreciated.

If you need futher information don't hesitate.

It would be nice to get PCI and SATA support in u-boot.

hi

i've tried using otg-port with this kernel, but i only get this

I'm using USB3.0 hub to extend 4 USB3.0 port with R2, but unfortunately, I met this problem：

I have tried to disable xhci module and only enable ehci, but ehci could not recognise my usb3.0 devices, so I am still looking for the solution.

I copied data from SD card into eMMC. It works fine, but only if SD card inserted (I removing SD card while board still in u-boot).
Maybe I need to copy u-boot separately?

i tried to add to add another bootmenu-entry via uEnv.txt:

kernel_4.14=uImage_4.14.33
kernel_4.9=uImage_4.9.92
boot49=mmc init; fatload mmc 0:1 ${loadaddr} ${bpi}/${board}/${service}/${kernel_4.9}; bootm
boot414=mmc init; fatload mmc 0:1 ${loadaddr} ${bpi}/${board}/${service}/${kernel_4.14}; bootm

bootmenu_7=8. Boot kernel 4.9.=run boot49
bootmenu_8=9. Boot kernel 4.14.=run boot414

i know i can modify existing kernel=-param to set another name for the uImage…this works, but the corresponding menuentry boot10 goes through some variables and also loads the env after selecting the entry.

the bootentry and my variables seems not to be loaded before displaying the menu…how can i change this?

i also tried with patches from @JackZeng, but it seems that uEnv.txt from sd.card is not load before menu is displayed

also the following commands on uboot-console did not load it:

mmc init

run loadbootenv

BPI-IoT> run loadbootenv
reading bananapi/bpi-r2/linux/uEnv.txt
1146 bytes read in 10 ms (111.3 KiB/s)

printenv => does not show my vars

bootmenu => does not display the menuentries

I just give a plain compilation and getting the below error.

Based on V1.1.1 release, both PWM4 and PWM4 are NOT working.

here i've found patch that seems to implementing vlan-control (for 7530, maybe 7623 used by bpi-r2 is similar):
https://github.com/openwrt/openwrt/blob/master/target/linux/mediatek/patches-4.4/0101-net-mediatek-add-gsw-mt7530-driver.patch

Please release the source code for the preloader binary included with this package.

Hello,

I'm not the big kernel developer, but I saw in
https://github.com/torvalds/linux/blob/master/drivers/net/ethernet/mediatek/mtk_eth_soc.c
the following code:

static int __init mtk_init(struct net_device *dev)
{
	struct mtk_mac *mac = netdev_priv(dev);
	struct mtk_eth *eth = mac->hw;
	const char *mac_addr;

	mac_addr = of_get_mac_address(mac->of_node);
	if (mac_addr)
		ether_addr_copy(dev->dev_addr, mac_addr);

	/* If the mac address is invalid, use random mac address  */
	if (!is_valid_ether_addr(dev->dev_addr)) {
		eth_hw_addr_random(dev);
		dev_err(eth->dev, "generated random MAC address %pM\n",
			dev->dev_addr);
	}

	return mtk_phy_connect(dev);
}

and I wonder, the function ether_addr_copy wants to copy the content from dev->dev_addr to mac_addr. Is this the plan? I have the feeling, that the parameters should be changed?

Kind regards, Andreas

Hello,

Is there a size limit for my SD card to work with Banana Pi?

Sincerely,

The MIPI driver in Kernel 4.4.70 is not working fine

because of codec it should be i2s...i2c 0 and 1 should be on GPIO, right?

I don't know its a kernel issue,but commands powerdown,shutdown -P now and init 0 do only halt. Board stays on (green led is lighting)

tried including some kernel-options but currently without luck

On R2 board, there is an onboard WIFI module MT6625, but right now the driver for it is not available.

Based on V1.1.1 release, the HDMI audio is not working,

I testd, and with a switch on board, I can boot uboot from internal emmc and external sd card ( cold start-up ).
It would be nice that it load/save environment in external sd card when it boot from external media. For example, u-boot can detect the status of the boot switch on board to do that.

See below image for details.

U-Boot partition size is 0x80000, but preloader copy only 300000 (0x0493e0).
So modern U-Boot (2019-07) can't be used with additional options.

Displayed correct:
[PART]partition name UBOOT
[PART]partition start block 0x200
[PART]partition size 0x80000
[PART]partition blks 0x400

Please change preloaders copy size to whole part size (0x80000).

The Linux kerne 4.4.70 can't boot successfully, it may hang after initializing mmc1, like below picture

This issue occurs when we enabled the mmc0 controller which is for EMMC, we will debug it.
