  1. Banana Pi M1+, kernel 4.19.38-sunxi, Debian stretch I needed to get bus i2c-2 working so I went to armbian-config, ticked i2c-2. After reboot I found some information from PMU were missing, some i2c buses were removed and some added. before crw-rw---- 1 root i2c 89, 0 May 26 18:24 /dev/i2c-0 crw-rw---- 1 root i2c 89, 1 May 26 18:24 /dev/i2c-1 after crw-rw---- 1 root i2c 89, 2 Jun 11 10:29 /dev/i2c-2 crw-rw---- 1 root i2c 89, 3 Jun 11 10:29 /dev/i2c-3 crw-rw---- 1 root i2c 89, 4 Jun 11 10:29 /dev/i2c-4 armbianEnv.txt verbosity=0 logo=disabled console=both disp_mode=1920x1080p60 overlay_prefix=sun7i-a20 rootdev=UUID=078696dc-d479-4821-8b2f-47fa5c0e05f1 rootfstype=btrfs fdtfile=sun7i-a20-bananapi-m1-plus.dtb extraargs=net.ifnames=0 biosdevname=0 overlays=i2c2 w1-gpio param_w1_pin=PI18 param_w1_pin_int_pullup=1 usbstoragequirks=0x152d:0x1561:u,0x2537:0x1066:u,0x2537:0x1068:u,0x0bc2:0x61b7:u,0x152d:0x9561:u I found i2c-1 changed to i2c-4: before after So I tried "overlays=i2c2 w1-gpio" to "overlays=i2c0 i2c1 i2c2 w1-gpio" in armbianEnv.txt but after another reboot i2c-0 bus was still missing. crw-rw---- 1 root i2c 89, 1 Jun 11 10:58 /dev/i2c-1 crw-rw---- 1 root i2c 89, 2 Jun 11 10:58 /dev/i2c-2 crw-rw---- 1 root i2c 89, 3 Jun 11 10:58 /dev/i2c-3 crw-rw---- 1 root i2c 89, 4 Jun 11 10:58 /dev/i2c-4 Swapping i2c1 and i2c4 in rpimonitor config files is not big problem for me, it takes lest than 1 minute, but with i2c-0 missing I lost access to information what is undefined in the picture bellow and I do not know how can I get i2c-0 and i2c-2 working at once. Note: This device was connected to poor power source, this is reason why USB voltage is low(4.372V) and battery charging was going very slowly (20mA). This was not I believe affecting badly this test :-).
  2. I bought 2pcs of BananaPi M1 Plus and received them about 2 weeks ago. I can't use legacy kernel because I want filesystem with compression support. This requirement matches only btrfs filesystem which is best supported on mainline kernels. Secondly this board supports lipol battery and this was second reason why I bought it. Even it cannot power sata drive while it is only battery powered (not tested on this board but on BananaPi few years ago) it was cheapest option with this feature among all SBC's on the market. Get right gpio pin numbering for my board is horrible experience for me. What I am missing is simple conversion software/script between what provides command cat /sys/kernel/debug/gpio and what is present in file: armbianEnv.txt I found one script but it is one way only. So I stick with with BPI-WiringPi2 => 'gpio readall' table and pin definition found there: https://bananapi.gitbooks.io/bpi-m1-bpi-m1-plus-/content/zh/bpi-m1+_gpio_pin_define.html
  3. I carry on watching movie so I will be not accessible for change
  4. ... and wifi is not accessible: [ 9.702977] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout [ 9.702998] brcmfmac: brcmf_bus_started: failed: -110 [ 9.703025] brcmfmac: brcmf_attach: dongle is not responding: err=-110 [ 9.719331] brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed
  5. And here is output of /sys/kernel/debug/gpio from the "virgin" image: onewire stays on value 271 like @Emil posted
  6. Yes, it was present. (I did not do any edit of that file and that image is about 2 weeks old.) Here is u-boot from image I downloaded few minutes ago. I made only one change, right after rootfstype=ext4 was added to armbianEnv.txt this: It is exactly same like in non working image with latest kernel.
  7. I check our community website, downloaded and flashed latest stretch image for bananapi and during routine upgrade right after logging in and etc I found that image is not latest because it started downloading kernel packages.
  8. I can get this message now but there was second problem maybe related to this, wifi stopped working. There was message in red about it.
  9. Hi @Emil, I can confirm this issue. It did not work either on my BananaPi M1 Plus after kernel upgrade. Problem is it stopped accepting pin value and whatever is in config file output of command below remained after reboot the same: cat /sys/kernel/debug/gpio Fastest solution is to run armbian-config and change kernel to previous version.
  10. Kernel version 4.19.13-sunxi does not accept param_w1_pin= while 4.14.70-sunxi is working. After every change I rebooted system and checked value for change with command below: "cat /sys/kernel/debug/gpio" Testing setup: BananaPi M1 Plus, sensors DS18B20, debian stretch.
  11. Not entire house but hopefully part of room only. However that room needed new painting, floor and furniture, all was in black. The fire brigade believed it was caused by faulty charging device/circuit charging the powerbank.
  12. This is (probably) last comment because all these boards (XU4) have been damaged during fire in my room. Fortunately that fire was extinguished quickly and I only lost some electronics. What I found out XU4 and HC1 cannot run ffmpeg on maximum cpu frequency 2Ghz, maximum stable frequency is 1,6Ghz and must be limited by cpufrequtils settings in /etc/default/cpufrequtils file otherwise unexpected shutdown occured. I am not going to replace these XU4 boards from this reason, keeping only 2x Orange Pi PC, Orange Pi PC plus, Olimex Micro and four Nanopi2. This is not only one reason, secondly it is very high current demanding board (4A or 6A) causing voltage drops, and therefore sata errors due to bus resets. I have never had these issues with Orange Pi PC boards family or Olimex Micro and I feel happy what community have done to support these.
