TinyFPGA-BX on Ubuntu 20.04: "Error: board TinyFPGA-BX not connected"

[ll16mojh]

Hi,

I've followed the Ubuntu 20.04 Quick Start for the TinyFPGA-BX but when I run apio upload I get:

matt@matt-WE62-7RJ:~/TinyFPGA-BX/Blinky$ apio upload
(DEBUG) Profile path: /home/matt/.apio/profile.json
(DEBUG) Home_dir: /home/matt/.apio
(DEBUG) Profile path: /home/matt/.apio/profile.json
(DEBUG) Home_dir: /home/matt/.apio
(DEBUG) Run Command: lsusb
(DEBUG) System_base_dir: /home/matt/.apio/packages/tools-oss-cad-suite
(DEBUG) System bin dir: /home/matt/.apio/packages/tools-oss-cad-suite/bin
(DEBUG) Executable file: /home/matt/.apio/packages/tools-oss-cad-suite/bin/lsusb
Error: board TinyFPGA-BX not connected

After installing a fresh copy of Ubuntu 20.04 and running update, upgrade and autoremove, all I have done is:

sudo apt install python3
sudo apt install python3-pip
sudo pip3 install -U apio
apio install -a
apio drivers --serial-enable

At this point it said something about restarting, for the dialout group to work (I forget the exact wording) so I restarted my laptop. then ran:

sudo usermod -a -G dialout $USER
exec su -l $USER
sudo pip3 install tinyprog

At this point, as per quick start, I plugged in my board. One red LED is on continuously, the other is pulsing slowly which I believe means its in bootloader mode?

tinyprog --update-bootloader
apio examples -d TinyFPGA-BX/Blinky
cd TinyFPGA-BX/Blinky/
apio upload

And this gave the result above. At no point did i see any errors or anything that seemed to indicate a problem to me, so I'm a bit confused what I've done wrong or am missing (probably something simple and embarrassing!).

If I run tinyprog while its plugged in it returns:

    TinyProg CLI
    ------------
    Using device id 1d50:6130
    Only one board with active bootloader, using it.

and after removing the board tinyprog returns:

    TinyProg CLI
    ------------
    Using device id 1d50:6130
    No port was specified and no active bootloaders found.
    Activate bootloader by pressing the reset button.

Any suggestions welcome!

Hello. I'm running into the same problem. The additional info is that I first tried using the the suggested apio version in the guide (apio==0.4.0b5), but had problems building. Then, I installed the latest version (0.8.4), and could build but not upload. Running lsusb (not the one in /tools-oss-cad-suite/bin/, but the system's one) I can see "Bus 001 Device 011: ID 1d50:6130 OpenMoko, Inc. " Running "tynyprog -l" also gives this same device id, but says there is no metadata for the board. Anyone had the same problem? I'm on Ubuntu 22.04.

TinyProg CLI
------------
Using device id 1d50:6130
Only one board with active bootloader, using it.
Boards with active bootloaders:

    /dev/ttyACM0: No metadata

And the result of uploading:

(DEBUG) Profile path: /home/tweber/.apio/profile.json (DEBUG) Home_dir: /home/tweber/.apio (DEBUG) Profile path: /home/tweber/.apio/profile.json (DEBUG) Home_dir: /home/tweber/.apio (DEBUG) Run Command: lsusb (DEBUG) System_base_dir: /home/tweber/.apio/packages/tools-oss-cad-suite (DEBUG) System bin dir: /home/tweber/.apio/packages/tools-oss-cad-suite/bin (DEBUG) Executable file: /home/tweber/.apio/packages/tools-oss-cad-suite/bin/lsusb Error: board TinyFPGA-BX not connected

Just additional info. In regard to my previous comment on not being able to "apio build" with apio==0.4.0b5, this could be fixed by changing the following:

On file: ~/.apio/packages/tool-scons/script/../engine/SCons/Util.py

Changed line 49, from: from collections import Iterable to: from collections.abc import Iterable

Although this allowed me to use "apio build" using apio==0.4.0b5, running "apio upload" still does not recognize the board.

Could you please try it again with the latest stable apio 0.9.2? (@ll16mojh and @towalker) I've tested the tinyFPGABX in my ubuntu 22.04 and it work ok. I am not sure if it has been fixed for you

[Obijuan]

I am closing this issue. Please feel free to reopen it if the problem remains

Was just trying to get started with an TinyFPGA-BX today and ran into the same issue -- will post logs tomorrow. Don't have access to that system ATM.

Although I can "apio build" with apio 0.9.5 (after setting the "top-module" name in apio.ini) , I still can't get it to upload to the board.

$ apio upload
Activate bootloader by pressing the reset button
Error: board TinyFPGA-BX not connected

Pressing the reset button makes no change in the response. Probably it is a problem with the board itself, which is very unfortunate, as it costed me much more than the original price due to transportation and importation costs to Brazil.

Hello, it seems the problem is related to missing metadata in boards shipped in 2023.

The unofficial workaround is discussed in https://github.com/tinyfpga/TinyFPGA-BX/issues/37
