Question about GPIO2C6 and GPIO2C7 pins. It is possible to set them to GPIO using wiringPi, but the voltage at HIGH output is lower than other GPIO pins. It is only about 1.95V. Upon further investigation, I found that a clock-like waveform is output during HIGH output. GPIO2C6 is exclusive with SPI5_CLK and GPIO2C7 is exclusive with SPI5_CSN, but it appears that the SPI5 clock continues to be output when each pin is set as a GPIO. Any suggestions?

I've tried multiple solutions but have come up short on all of them. Right now I'm trying to get the WPEWebkit cog browser going. So far, no luck. I can get it to "start" in a Weston session (I've installed the Wayland libMali driver from the RockChip repo). However, it only displays an on-screen keyboard and no browser. Any suggestions?

Can you upload rockchip to Android OS 12 image and release a version? I have ESP32 and Tinker Board 2S. I need to use Tinker Board's Uart as well, and I also need connection to ESP 32's Access Point To do this, Android OS Version must be 12 or higher. Also, rockchip must be included within the OS for use with the Tinker Board (Reference URL: https://github.com/TinkerBoard-Android/rockchip-android-manifest) Is it possible to distribute including a rock chip within Android OS 12 version in the near future?

Hi, I am following the URL below to start up SPI with WiringPi library. I can see spidev in /dev on my TinkerBoard2S. Therefore, I believe the spi settings are reflected at boot time. linaro@linaro-alip:~/Desktop/CSampleCode/spiSpeed$ ls /dev/spidev* /dev/spidev1.0 /dev/spidev5.0 When I run the sample code, I get an error "Unble to open SPI device". Can you please tell me the cause and countermeasure? linaro@linaro-alip:~$ cd /home/linaro/Desktop/CSampleCode/spiSpeed/ linaro@linaro-alip:~/Desktop/CSampleCode/spiSpeed$ sudo ./spiSpeed +-------+--------+----------+----------+-----------+------------+ | MHz | Size | mS/Trans | TpS | Mb/Sec | Latency mS | +-------+--------+----------+----------+-----------+------------+ Unable to open SPI device: No such file or directory Board:TinkerBoard2S Linux version:4.4.194 Best regards,

I'm trying to reinstall the OS. I'm using Balena to flash the device, but every time I connect it, my computer doesn't recognize it. It used to recognize it when I changed the system before, but not anymore. I also tried using an SD card as the manual suggests, but I'm encountering the same error with the eMMC.

Hello everyone! I have a Tinker Board 2s and it also has a touchable LCD display. The products of display model are as follows >> 9.3inch Capacitive Touch Display, High Brightness, 1600×600, Optical Bonding Toughened Glass Panel, HDMI Interface, IPS | 9.3inch 1600x600 LCD (waveshare.com) The display and the Tinker Board are connected using HDMI only. And the os image on the Tinker Board is Android 12. (Tinker_Board_2-Android11-v2.0.8-20220503) First of all, the lcd display on the Tinker Board shows Android's screen well. However, the screen is streched a bit vertically. I,ve also tried the following ways to solve this problem myself. on the Tinker Board 2s : Setting > Display > HDMI > (SCREEN SETTING) HDMIA: Change Resolution But it didn't work.... How can I change the resolution to a normal state where the vertical is not stretched? Or does Tinker Board not support the resolution of the display I use....? I would appreciate it if you could let me know the solution! Thank you in advance.

Hi all - here is something really hard to understand. An Asus 2S, standard Linux image, no modifications. Configured as a Hotspot. Here is the configuration file Device shows up - Select but can't connect. This "can't connect" is weird. Fails connecting from MacOS, fails connecting from iPadOS but connects from an Android tablet. Here is the output while Apple Mac is trying connecting Sep 21 16:03:31 OEI-XXXX kernel: RTW: ============ STA [88:66:5a:11:3e:e1] =================== Sep 21 16:03:31 OEI-XXXX kernel: RTW: mac_id : 0 Sep 21 16:03:31 OEI-XXXX kernel: RTW: wireless_mode : 0x0b Sep 21 16:03:31 OEI-XXXX kernel: RTW: mimo_type : 2 Sep 21 16:03:31 OEI-XXXX kernel: RTW: static smps : N Sep 21 16:03:31 OEI-XXXX kernel: RTW: bw_mode : 20MHz, ra_bw_mode : 20MHz Sep 21 16:03:31 OEI-XXXX kernel: RTW: rate_id : 2 Sep 21 16:03:31 OEI-XXXX kernel: RTW: rssi : -1 (%), rssi_level : 0 Sep 21 16:03:31 OEI-XXXX kernel: RTW: is_support_sgi : Y, is_vht_enable : N Sep 21 16:03:31 OEI-XXXX kernel: RTW: disable_ra : N, disable_pt : N Sep 21 16:03:31 OEI-XXXX kernel: RTW: is_noisy : N Sep 21 16:03:31 OEI-XXXX kernel: RTW: txrx_state : 0 Sep 21 16:03:31 OEI-XXXX kernel: RTW: curr_tx_rate : CCK_1M (L) Sep 21 16:03:31 OEI-XXXX kernel: RTW: curr_tx_bw : 20MHz Sep 21 16:03:31 OEI-XXXX kernel: RTW: curr_retry_ratio : 0 Sep 21 16:03:31 OEI-XXXX kernel: RTW: ra_mask : 0x000000000fffffff Sep 21 16:03:31 OEI-XXXX kernel: RTW: send eapol packet 1/4 Sep 21 16:03:31 OEI-XXXX kernel: RTW: set group key camid:1, addr:00:00:00:00:00:00, kid:1, type:TKIP Sep 21 16:03:31 OEI-XXXX kernel: RTW: recv eapol packet 2/4 Sep 21 16:03:31 OEI-XXXX kernel: RTW: send eapol packet 3/4 Sep 21 16:03:31 OEI-XXXX kernel: RTW: recv eapol packet 4/4 Sep 21 16:03:31 OEI-XXXX kernel: RTW: set pairwise key camid:4, addr:88:66:5a:11:3e:e1, kid:0, type:AES Sep 21 16:03:37 OEI-XXXX kernel: RTW: OnDisassoc(wlp1s0) reason=8, ta=88:66:5a:11:3e:e1 Sep 21 16:03:37 OEI-XXXX kernel: RTW: clear key for addr:88:66:5a:11:3e:e1, camid:4 Sep 21 16:03:38 OEI-XXXX kernel: RTW: ============ STA [88:66:5a:11:3e:e1] =================== Sep 21 16:03:38 OEI-XXXX kernel: RTW: mac_id : 0 Sep 21 16:03:38 OEI-XXXX kernel: RTW: wireless_mode : 0x0b Sep 21 16:03:38 OEI-XXXX kernel: RTW: mimo_type : 2 Sep 21 16:03:38 OEI-XXXX kernel: RTW: static smps : N Sep 21 16:03:38 OEI-XXXX kernel: RTW: bw_mode : 20MHz, ra_bw_mode : 20MHz Sep 21 16:03:38 OEI-XXXX kernel: RTW: rate_id : 2 Sep 21 16:03:38 OEI-XXXX kernel: RTW: rssi : -1 (%), rssi_level : 0 Sep 21 16:03:38 OEI-XXXX kernel: RTW: is_support_sgi : Y, is_vht_enable : N Sep 21 16:03:38 OEI-XXXX kernel: RTW: disable_ra : N, disable_pt : N Sep 21 16:03:38 OEI-XXXX kernel: RTW: is_noisy : N Sep 21 16:03:38 OEI-XXXX kernel: RTW: txrx_state : 0 Sep 21 16:03:38 OEI-XXXX kernel: RTW: curr_tx_rate : CCK_1M (L) Sep 21 16:03:38 OEI-XXXX kernel: RTW: curr_tx_bw : 20MHz Sep 21 16:03:38 OEI-XXXX kernel: RTW: curr_retry_ratio : 0 Sep 21 16:03:38 OEI-XXXX kernel: RTW: ra_mask : 0x000000000fffffff Sep 21 16:03:38 OEI-XXXX kernel: RTW: send eapol packet 1/4 Sep 21 16:03:38 OEI-XXXX kernel: RTW: recv eapol packet 2/4 Sep 21 16:03:38 OEI-XXXX kernel: RTW: send eapol packet 3/4 Sep 21 16:03:38 OEI-XXXX kernel: RTW: recv eapol packet 4/4 Sep 21 16:03:38 OEI-XXXX kernel: RTW: set pairwise key camid:4, addr:88:66:5a:11:3e:e1, kid:0, type:AES Sep 21 16:03:44 OEI-XXXX kernel: RTW: OnDeAuth(wlp1s0) reason=15, ta=88:66:5a:11:3e:e1 Sep 21 16:03:44 OEI-XXXX kernel: RTW: clear key for addr:88:66:5a:11:3e:e1, camid:4 Sep 21 16:04:00 OEI-XXXX kernel: invalid destination resolution act_w = 0, act_h = 0 Similar output when trying from an iPad When trying from an Android Tablet - it connects!!!!!
