Banana Pi BPI-R2 Pro smart router board with Rockchip RK3568 chip

new sample ready:


I guess 2 typos:

  • hdmi in (should be out)
  • usb-otg is named debug-uart.

Is mt7531 same as on r64 (only used port 5 with rgmii)? Would be nice if some more devs get the board.

Is rtc/reset now working? Any other changes like iodomain? Just want to be sure no damage happens if using my/your current config.

Would be nice to have the sw1 (for disabling emmc) reachable from outside (like power/reset).

1,yes,it is HDMI out 2,it use USB to uart ,not USB-otg , we use a USB-3.0 to burn .(top of 2 use 3.0 interface)

yes ,it is same as BPI-R64, but dirive need some time to do .

when we finished this hardware test ,can send sample to you ,thank you.

Thanks,i have previous version and imho makes more sense that other devs can test too.

Was iodomain changed?

adding switch driver should be no big part as most part is mainline.if using p5 rgmii init is ready to,imho only ethsys/mtk bindung needs to be reworked.

Send sample.

Looking forward to run opnsense on this minux MTK driver

Banana Pi BPI-R2 Pro Public sale,

Wow nice and I still waiting for development sample. Good luck.

please send mail to [email protected] check sample .

have you fixed the headphone-detection? in my version this pin is always gnd/0 so microphone does not switch to the headset one

hi Frank,

please refer to the below,

   rk_headset: rk-headset {
            status = "okay";
            compatible = "rockchip_headset";
            headset_gpio = <&gpio3 RK_PC2 GPIO_ACTIVE_HIGH>;
            pinctrl-names = "default";
            pinctrl-0 = <&hp_det>;
            io-channels = <&saradc 2>;    //HP_HOOK pin

… … &pinctrl { headphone { hp_det: hp-det { rockchip,pins = <3 RK_PC2 RK_FUNC_GPIO &pcfg_pull_up>; }; };

… …

hi Frank, Maybe you need enable internal pull-up

&pinctrl { headphone { hp_det: hp-det { rockchip,pins = <3 RK_PC2 RK_FUNC_GPIO &pcfg_pull_up>; }; };

Already tried pullup and read out gpio (without mapping to soundcard)…always 0


Is no valid upstream compatible. Downstream it is in

drivers/headset_observe/rockchip_headset_core.c:180:	{ .compatible = "rockchip_headset", },

this driver seems to read out gpio (looks like only as busy-indicator) then adc and then gpio again in rk_headset_irq_hook_adc.c/hook_work_callback

i’m not sure if the gpio is only some kind of hw-interrupt to trigger the adc-read, but at least for this there is no mainline driver, and porting this driver is much work for this small functionality

from hw view:

Adc works but gpio does not (alone). Have not found a way in upstream to use adc for mic switch

@zuowei8 can you explain how it should work? is the gpio a hw-interrupt to trigger the adc-read? maybe i can write a simpler driver to archive the same

have added the rk_headset driver to my 5.19-hdmi-tree, but it seems not triggering the mic-change, used same settings in dts like in bsp

root@bpi-r2pro:~# zgrep 'HEADSET' /proc/config.gz
root@bpi-r2pro:~# uname -a
Linux bpi-r2pro 5.19.0-rc1-bpi-r2pro-r2pro-hdmi #1 SMP PREEMPT Wed Jun 15 15:07x

i see this messages, but it seems driver still does not switch mic to headset

root@bpi-r2pro:~# dmesg | grep -i headset

any idea? on plugging in/out i see headset_interrupt messages in dmesg, but evtest does not show any change…and maybe i need to map this event to also somehow in userspace

edit: get it so far:

means driver recognizes the change, but mic is not switched yet to headphone…i see in driver there is some reference to an extcon_* and imho input-device should change too…currently debugging

HEADSET_OUT should set input device in headset_interrupt and !=HEADSET_OUT in hook_work_callback

inout device ist not updated because headset->hook_status is always HOOK_UP, i’m not sure whats the reasing for HOOK-STATUS, but is is set only to down in hook_work_callback which is not called if headset is removed. looks for me redundant with headset_info->headset_status = [HEADSET_IN,HEADSET_OUT]

Hi Together,

i recently ordered a BPI-R2 Pro but I cannot find the schematic/component placement anywhere. Can anyone provide it to me?

Thanks, Eric

i have the schematic (not component placement), but i’m instructed not to share it. which part do you need?

@sinovoip can you/i share it now or only parts?
