gpio-issue solved so far…gpio was blocked by activated i2c1…so if the special-function is enabled in dts, the direct gpio-access is blocked

except of the event-info/warning all is good now

Bluetooth: hci0: last event is not cmd complete (0x0f)

the change seems to create problems detecting mmc-rootfs

sometimes i get this message and boot-prcess hangs

Waiting for root device /dev/mmcblk0p2...

@linkerosa have you an idea regarding preloader and emmc?

Hello, I want to attach an SSD and need SATA 3 speed (ie. 6 Gbps). Which of the boards has all these features: Gigabit Ethernet, USB 3, SATA 3 ? Thx

Update: in the following thread someone wrote “The BPI-R2 has two SATA 3.0 Ports / 6 Gbps and not SATA II” ( SATA Performance + Max Disk Size ). But in many product descriptions only SATA 2 is mentioned, also in the Hardware spec wiki ( http://wiki.banana-pi.org/Banana_Pi_BPI-R2#Documents ) it says “Two SATA 2.0 Port”

What is correct?

frank-w · February 10, 2019, 8:42am

Regardless if it is sata 3,you will not reach the speed of 6gbit/s. Why does it matter for you?

Btw. This thread is for r64

mutluit · February 10, 2019, 4:29pm

Hi, I’m just a newbie, don’t know yet the features of the different boards, I wongly assumed the R64 is the successor to R2; it seems it is rather the W2.

I just wanted evaluate the possibilities of building a backup-box to be used in LAN with multiple client-machines to backup, so the LAN and the storing to the SSD should be as fast as possible as this shall be a “realtime” backup solution, ie. always on, though incremental, and it should serve as many clients as possible. So I assumed getting full SATA III speed, but later learned that it’s not a full SATA III like you remarked too. I need to find a cheap HW for this project. Today I found another one (Rock Pi 4 for $39), it looks promising, but it lacks SATA; has only USB3, and not clear yet if one can use Debian on it. It’s not easy to find the right HW for the project as I’m more a SW guy…

frank-w · February 10, 2019, 7:35pm

imho most SOCs don’t have native SATA-support…i don’t know how it realized on R2/R64, imho as pcie-sata-bridge, where mini-pcie has limitation to 500Mbit/s, so it is not possible to reach sata2/3-throughput…but please make a new thread if needed

for GPIO, how to disable pwm-mapping?

i get this error for pin7 (gpio101):

root@bpi-r64:~# GPIO_NO=$((409+101)) 
root@bpi-r64:~# echo $GPIO_NO > /sys/class/gpio/export
[  365.604377] mtk-pinctrl 10211000.pinctrl: pin PWM7 already requested by 11006000.pwm; cannot claim for pinctrl_mt7622:510
[  365.615703] mtk-pinctrl 10211000.pinctrl: pin-101 (pinctrl_mt7622:510) status -22
-bash: echo: write error: Invalid argument

but nice that here is a message for blocked access

can i disable it from userspace or only in dts?

it seems it is this section in dts:

github.com

frank-w/BPI-R2-4.14/blob/625defb974d21905cb647abdfae58476e0575d26/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64-gpio.dts#L497


	};


	watchdog_pins: watchdog-pins {
		mux {
			function = "watchdog";
			groups = "watchdog";
		};
	};
};


&pwm {
	pinctrl-names = "default";
	pinctrl-0 = <&pwm7_pins>;
	status = "okay";
};


&pwrap {
	pinctrl-names = "default";
	pinctrl-0 = <&pmic_bus_pins>;


	status = "okay";

only pwm7 seems to be defined, why not the others? maybe we can define pwm1-7 (except 3, i’ve did not found on header)

can i use generic pwm-node and define subnodes for pwm1-7?

something like this (of course i have to define the pwmx_pins):

&pwm {
	pinctrl-names = "default";
	status = "okay";
	pwm1{
		pinctrl-0 = <&pwm1_pins>;
	}
	pwm2{
		pinctrl-0 = <&pwm2_pins>;
	}
	pwm4{
		pinctrl-0 = <&pwm4_pins>;
	}
	...
}

Sure! you could add it if you want to do that.

can i use generic pwm-node and define subnodes for pwm1-7? something like this (of course i have to define the pwmx_pins):

You can take a look at i2c/spi nodes to understand how to add “generic pin configuration” (via function/group) in dts

frank-w · May 4, 2019, 6:15pm

how can i use emmc? it seems the sd-card-preloader does not work for emmc, atf should be loaded after uboot, but i don’t get into uboot

btw. have not get pwm working yet…also no answer from sean

gpio-issue solved so far…gpio was blocked by activated i2c1…so if the special-function is enabled in dts, the direct gpio-access is blocked

How did you deactivate i2c?

frank-w · August 10, 2020, 5:56am

As pointed by @linkerosa it’s defined in dts

https://elixir.bootlin.com/linux/v5.0-rc5/source/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts#L139

Here status needs to be set to disabled

Redevice · August 10, 2020, 6:58am

But that doesn’t work for PWM. Changing the status to disable I have all the same error

maybe you need this:

reukiodo · July 25, 2023, 1:53am

Am I understanding correctly that the SATA and mPCIe (CN8 or CN25?) cannot both be used at the same time?

According to https://wiki.banana-pi.org/Getting_Started_with_R64#Sata needs echo 0 > /sys/class/gpio/gpio499/value while mPCIe (CN8 or CN25?) need echo 1 > /sys/class/gpio/gpio499/value which are opposing.

This would mean that it can’t do both WAN AND SATA at the same time? Or is CN8 the correct mPCIe port for WAN? Was CN25 meant for mPCIe SSD?

reukiodo · July 25, 2023, 1:55am

Also, I assume that the PoE module needs to be soldered on to the BPi-R64 board. Does this supply power to the ethernet ports, or only allow the board to be powered by the WAN port?

frank-w · July 25, 2023, 6:05am

You can use PCIE1/cn8 or SATA by switching GPIO90 via gpio-hog (asm_sel) in dts,so it is blocked in userspace

meong_pus · July 29, 2023, 1:06pm

Has anyone tried to attach multiple AX card like MT7915 non DBDC? or should i choose bpi-r3 route and add m.2 AX card? planning to make tri-radio AP.

thanks
