    • 1. Check power supply, check SD card and check other people experiences

      Power supply issues are one of the three biggest issues you'll face when starting with Single Board Computers (SBCs). SD card issues, whether fake or faulty, are another and issues resulting from poor board design is the other common issues you can encounter.   Power supply issues can be tricky. You might have a noisy power supply that works with one board because it has extra filtering, but won't work with another. Or you're using that cheap phone charger because your board has a microUSB connector, and it is either erratic, or doesn't start up, or even becomes the cause of some SD card issues.    Some tips to avoid the most common causes of problems reported:   Don't power via micro USB  - unless you have optimised your setup for low power requirements. Micro USB is great for mobile phones because they are simply charging a battery. It's bad for SBCs. Yes, it does work for a lot of people, but it also causes more problems and headaches over time than it is worth, unless you know exactly what you are doing. If you have a barrel jack power connector on your SBC, use it instead! If there is an option for powering via header connections, use that option!
        Don't use mobile phone chargers. They might be convenient and cheap, but this is because they are meant for charging phones, not powering your SBC which has particular power requirements.
        When you are evaluating a power supply, make sure you run some stress tests on your system to ensure that it will not cause issues down the path.   (Micro) SD card issues can be sneaky. They might appear right at the start causing strange boot and login errors, or they might cause problems over time. It is best to run a test on any new SD card you use, to ensure that it really is what it is, and to ensure that isn't faulty. Armbian provides you a simple way to do this   --   armbianmonitor -c /path/to/device/to/test  
    • 2. Make sure to collect and provide all necessary information

      We can only help if you provide quality information for us to work with. All stable images from the download section are tested, most stable upgrades are tested and we have tens of thousands of users. Even with regular and extensive testings, bugs sometimes do slip through. This is a voluntary support service and is unrelated to board makers, and is not obligated to provide you any answers. Repeated asking the same questions because you're not happy with the answers will result in you being ignored.

      Before you post a question, use the forum search as someone else might have already had the same problem and resolved it. And make sure you've read the Armbian documentation. If you still haven't found an answer, make sure you include the following in your post:   1. Logs when you can boot the board: armbianmonitor -u (paste URL to your forum post)   2. If your board does not boot, provide a log from serial console or at least make a picture, where it stops.   3. Describe the problem the best you can and provide all necessary info that we can reproduce the problem. We are not clairvoyant or mind readers. Please describe your setup as best as possible so we know what your operating environment is like.     We will not help in cases you are not using stable official Armbian builds, you have a problem with 3rd party hardware or reported problem would not be able to reproduced.

Espressobin mPCIe Wifi adapter not recognised

Hi there,

 

I've recently ordered a miniPCIe Wifi adapter for the Espressobin, so it can act as WiFi Access Point. The device does recognise the card (using `pci` in u-boot lists the device), but the kernel doesn't. All I can see is the following in dmesg output:

[    2.969072] advk-pcie d0070000.pcie: link never came up
[    2.974496] advk-pcie d0070000.pcie: PCI host bridge to bus 0000:00
[    2.980995] pci_bus 0000:00: root bus resource [bus 00-ff]
[    2.986325] pci_bus 0000:00: root bus resource [mem 0xe8000000-0xe8ffffff]
[    2.993793] pci_bus 0000:00: root bus resource [io  0x0000-0xffff] (bus address [0xe9000000-0xe9)
[    4.435260] advk-pcie d0070000.pcie: Posted PIO Response Status: CA, 0xe00 @ 0x0

u-boot is at its latest version from the Espressobin website. The affected Wifi card is a Compex WLE600VX which should work with the ath10k driver.

 

What options do I have? GlobalScale (the manufacturer of the Espressobin board) recommended to buy their miniPCIe Wifi module, which needs to be shipped from overseas which I want to avoid if possible. Thanks for any hints.

Thanks for your reply. This makes some things more clear to me.

 

For the time being, I've ordered a USB-based WiFi AC speed card for testing purposes which works great so far.

 

I'm just wondering why other cards may work while these ath10k cards have issues. As far as I know both the Espressobin and the Clearfog uses the Marvell u-boot from Github. However, I'm not really willing to flash a custom-built u-boot version (and probably find a way to incorporate changes to get it running) because some people have reported to brick their device when flashing a custom-built u-boot firmware. I'm absolutely new to this embedded stuff and have dig into this to figure out how to work with it.

We have very good results with Realtek 8811/8812/8814. I hope you order those? :)

I managed to brick my Espressobin but was able to bring it back. Clearfog is different enough beast and is here for some time, while Espressobin still has glitches here and there. It is safe to update u-boot from our download - those are the latest builds: https://dl.armbian.com/espressobin/u-boot but the problem with non-working ath10 card exists.

Yeah, I basically ordered one with an rtl8811au chip. Works fine so far. I'm able to get up to 116 Mbits in AC mode, 109 in N mode from short distance. I guess a miniPCIe card will do even better.
