  1. Any news about this issue ? Thanks in advance. Regards, Antony
  2. Hello, I am using nanoPi Neo Core with mini shield nanoPi NEO CORE/CORE2. The OS that i am using is Armbian stretch downloaded from this link : https://www.armbian.com/nanopi-neo/ The armbian image that I am using is : Armbian_5.65_Nanopineo_Debian_stretch_next_4.14.78 If I try to enable SPI without doing update and upgrade, it works. If I do update and upgrade and then try to activate SPI, it is not working. I dont find the spi device in /dev. Any idea what could be the problem? P.S: Before last week, I didn't have this problem. So I think it is related to a recent update done on this image. Thanks in advance. Regards,
  3. Hello, I am using nanoPi Neo Core with mini shield nanoPi NEO CORE/CORE2. The OS that i am using is Armbian stretch downloaded from this link : https://www.armbian.com/nanopi-neo/ The armbian image that I am using is : Armbian_5.65_Nanopineo_Debian_stretch_next_4.14.78 What I am trying to do is enable hotspot. Based on what you said, if I am using a wifi USB adapter, the script will not work correctly? I am trying to setup the hotspot using armbian-config. I chose my default interface the eth interface. And I want to use the wifi usb adapter for hotspot. It should work? When I setup the hotspot using armbian, it takes more then 30 minutes for the script to finish. Is this normal? Thanks in advance.
  4. The error that I am getting in the end of the script that configure hotspot using armbian-config is the following :
  5. Hello, I am using nanoPi Neo Core with mini shield nanoPi NEO CORE/CORE2.

I followed the following tutoriel that is already published on this forum : When I try to start the hotspot using armbian-config, network manager stop working. I tried to do a reboot but it didn't work. And network manager doesn't start again. the cause of this error is : NetworkManager[879]: Failed to read configuration P.S: I have an ethernet connection and I have a wifi adapter using a USB (https://www.friendlyarm.com/index.php?route=product/product&product_id=143). Any idea how to solve this problem? Thanks in advance. Regards, Antony
  6. Hello @martinayotte. I copied the /etc/fstab of the image that works in the /etc/fstab of the image that is not working. Then I changed the UUID of the corresponding disks (SSD and SD). It worked I can now use the new image of armbian and boot from SD and have the filesystem on rootfs. Thanks for the help again. Regards, Antony
  7. @martinayotte i just tested the hardware flow control with the newest armbian neo core image that i donwloaded today from the website. Both RTS and CTS worked with this image. So i have the following results with these two images: *Armbian_5.38_Nanopineo_Debian_stretch_next_4.14.14 : 1) hardware flow control doesn't work normally. 2) mount the file system on ssd disk and boot from sd card work normally. *Armbian_5.65_Nanopineo_Debian_stretch_next_4.14.14 : 1) hardware flow control work normally. 2) mount the file system on ssd disk and boot from sd card doesn't work normally. Hope I helped you with the tests that I did. Regards, Antony
  8. @martinayotte I forgot to mention this information. I am using the following nanopi neo core image : Armbian_5.38_Nanopineo_Debian_stretch_next_4.14.14 The reason why I am using this image is using the SSD disk for file system with the SD card for boot. We already discussed this issue with you : Regards, Antony
  9. @martinayotte thanks again for the help. Regards, Antony
  10. Thanks for your reply @martinayotte. I am not using a RS485 halfduplex operation. I have two devices that are communicating using serial port (UART) and I would like to use hardware flow control because it is recommended for the communication that I am doing. The RTS and CTS in my case will help the two devices know if they are ready to send/receive data. What I am finding strange is that when I activate RTS and CTS, the mode function of the CTS GPIO only switch to ALT5. The RTS GPIO stays as "OUTPUT mode". Shouldn't the RTS GPIO switch also to ALT5? Regards, Antony
  11. Hello again, I tested the hardware flow control after adding "param_uart1_rtscts=1" to /boot/armbianEnv.txt. The CTS of the nanopi worked normally. (The GPIO mode of the CTS switched to ALT5). The RTS didn't work. (The GPIO mode of the RTS didn't switch to ALT5). I did the serial communication test between the nanopi and a raspberrypi. Why do you thing the RTS is not working? Thanks in advance. Regards, Antony
  12. Hello guys, I am trying to use hardware flow control over the uart 1 of a nanopi neo core that I am using with a minishield. The GPIO pins of RX,TX,RTS and CTS of uart 1 based on this documentation (http://wiki.friendlyarm.com/wiki/index.php/Mini_Shield_for_NanoPi_NEO_Core/Core2) are G6,G7,G8 and G9. First of all I downloaded WiringNP in order to see the status of each GPIO. Before activating the rts cts on uart1, the figure "beforeActivatingRTSCTS" is the output of the command "gpio readall" . Then I added to the /boot/armbianEnv.txt the following overlay : param_uart1_rtscts=1 I rebooted the nanopi. After reboot, the figure "AfterActivatingRTSCTS" is the output of the command "gpio readall". As you can see, the GPIOG9 switched to ALT5 but GPIOG8 stayed the same. I am supposing that the ALT5 is the Alternate function for RTS CTS. Is that right? Why the GPIOG8 didn't change to ALT5 after activating the RTS CTS ? Is there something that I am doing wrong to activate these pins? Do I need to instruct the serial port driver to use the hardware flow control signals? Thanks in advance. Regards, Antony
  13. Hello again, I did the test again. I executed nand-sata-install script using armian-config. At the end, I didn't rebbot. I mounted the SSD disk manually. I modified /mnt/nand-sata-install.g3nZk2/etc/fstab and removed the line corresponding to the EMMC storage. I checked that /boot/armbianEnv.txt is pointing to the SSD disk. I rebooted and got the following serial debug logs. I got the same problem. P.S: I checked /etc/fstab before rebooting. I figured out that the EMMC storage is only mounted in /etc/fstab. I am really out of ideas regarding this problem. Hope what I explained and the logs help you figure out the problem. Regards, Antony SerialDebug.txt
  14. @martinayotte I forget to remove it from fstab when I did the test again. I will do it now and get back to you. Thank you really for the help. Antony
  15. @martinayotte I retried the test with the most recent image of nanopi neo core. Here is the full serial debug logs. Like you said, I guess that I didn't send the full logs previously. As you see from the logs, there is emergency mode. I tried to press Ctrl D like they said but it didnt worked. What do think about that? Regards, Antony SerialDebug.txt
