  1. Thanks everyone. With 12v power it looks definitely better: $ sudo kermit kermit-usb0 Connecting to /dev/ttyUSB0, speed 115200 Escape character: Ctrl-\ (ASCII 28, FS): enabled Type the escape character followed by C to get back, or followed by ? to see other options. ---------------------------------------------------- E > E > E > E > E >? h/? - print this help screen r yyyyyyyy - read register/memory at address yyyyyyyy in hex w yyyyyyyy zzzzzzzz - write zzzzzzzz to address yyyyyyyy in hex j yyyyyyyy - jump to address yyyyyyyy in hex x y - change the boot mode, where y is in hex a - UART control passed to AP CPU ROM c - UART control passed to CM3 CPU ROM > E > I already thought I lost that board. I hope tomorrow I'll get it show some more things :-)
  2. $ cat kermit-usb0 set line /dev/ttyUSB0 set speed 115200 set carrier-watch off set flow-control none set handshake none set prefixing all set streaming off set parity none connect Those are my kermit settings.
  3. Hi @barish I attach photo with my current switch positions. I believe, they are correct for UART mode (J11:[2-3]; J3:[1-2] J10:[1-2]), according to http://wiki.espressobin.net/tiki-index.php?page=Ports+and+Interfaces#Boot_selection I find that page quite confusing, because the switch numbers on the images are listed in other order than in the table below with their meanings. I disconnected HDD, so it should get enough power from USB. After attaching the espressobin to my laptop, its green LED turns on and dmesg says: [102505.613224] usb 1-3: new full-speed USB device number 50 using xhci_hcd [102505.761832] usb 1-3: New USB device found, idVendor=067b, idProduct=2303 [102505.761834] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [102505.761835] usb 1-3: Product: USB-Serial Controller D [102505.761836] usb 1-3: Manufacturer: Prolific Technology Inc.

Only after Ctrl+] it exits. Kermit behaves the same way on that device. If you see I can do something else - please let me know. Andrius
  4. Thanks for remembering me. No solution yet. Now on vacation, so I cannot exactly post all the details. I used micro-USB for power and serial. The connection settings I used were the same as previous times when I used to connect successfully. I'll post them when I come back. I tried kermit, minicom and miniterm on device which is listed in dmesg output. Andrius
  5. Miniterm freezes just like kermit and minicom :-(
  6. How do I flash something without access to some command-line? As I understand, for any recovery method I need some working "serial" connection? What can I do if I cannot connect to the board using minicom or kermit?
  7. Thank you for suggestions. I tried instructions here: and here: http://wiki.espressobin.net/tiki-index.php?page=Ports+and+Interfaces#Boot_selection But nothing really changed. After changing switches to "UART mode" and connecting via USB, the kermit command line still freezes. Any other suggestions? Please... Andrius
  8. Hello, last week I performed an apt upgrade on my espressobin (ubuntu) and now it does not boot :-( I believe there were some updates to kernel and armbian firmware. Then I pulled out its SD card and tried to connect it to my PC using micro-USB and see what it says using minicom and kermit. But it does not say anything and the console freezes. The board I have is a kickstarter board with 1GB RAM. I suspect the upgrade has broken the board in some way. Can you suggest some way to fix it please? Kind regards Andrius
  9. Hello, I am trying to use my espressobin board which currently runs Bionic with Hauppauge USB DVB-T tuner. It seems the default kernel does not have a module for it. How do I build and use it? Can I build the module on the same device or should I use another machine for that? Kind regards Andrius
  10. No. Will try if time allows. Won't the resulting image loose the optimizedness of armbian?
  11. It seems Lane's reply was directed at me. Thank you. After reading this thread I concluded Thomas' OMV image won't boot on espressobin. Do you know any other armbian images for espressobin? Lane's howto refers to some expertise I do not possess :-)
  12. I tried the following: - downloaded http://kaiser-edv.de/tmp/NumpU8/OMV_3_0_72_Espressobin_4.4.52.7z - unzipped and burned into microSD card using Etcher on linux mint - sudo sfdisk -l /dev/mmcblk0 shows: Disk /dev/mmcblk0: 7,4 GiB, 7948206080 bytes, 15523840 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x2b1c1cab Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 2048 3618815 3616768 1,7G 83 Linux - mount shows: /dev/mmcblk0p1 on /media/andrius/cc8b4e1a-3743-473d-8711-4176d1ba2858 type ext4 (rw,nosuid,nodev,relatime,uhelper=udisks2) - I inserted it into the espressobin - powered espressobin using its power adapter with a barel - connected espressobin microUSB to the computer USB. No other devices are connected to espressobin, just microUSB and microSD - after pressing RESET button kermit shows: Booting Trusted Firmware BL1: v1.2(release):armada-17.02.0: BL1: Built : 09:27:33, Apr 24 2NOTICE: BL2: v1.2(release):armada-17.02.0: NOTICE: BL2: Built : 09:27:34, Apr 24 20NOTICE: BL31: v1.2(release):armada-17.02.0: NOTICE: BL31: U-Boot 2015.01-armada-17.02.0-g48dc978 (Apr 24 2017 - 09:27:28) I2C: ready DRAM: 1 GiB Board: DB-88F3720-ESPRESSOBin CPU @ 800 [MHz] L2 @ 800 [MHz] TClock @ 200 [MHz] DDR @ 800 [MHz] Comphy-0: PEX0 2.5 Gbps Comphy-1: USB3 5 Gbps Comphy-2: SATA0 5 Gbps Now running in RAM - U-Boot at: 3ff2b000 U-Boot DT blob at : 000000003fa18168 MMC: XENON-SDHCI: 0 SF: Detected W25Q32DW with page size 256 Bytes, erase size 4 KiB, total 4 MiB PCIE-0: Link down SCSI: SATA link 0 timeout.
