Just wasted a few hours trying to get Ubuntu working on a16GB Kingston thumbdrive. Now its saying cannot locate several pkgs. Arrggghh.
[edit: ok I figured it out]
I will have 1 and perhaps 2 Linux laptops to in block people.
It you new help donât for get to bring your board and record videos of success for the blog
Iâm moving along slowlyâŚbut moving. Just troubleshooting some SDK issues but I feel closeâŚso close.
edit: woo - got it, just need to flash to the board which I will do tomorrow. Will come in early.
Hi Zephyrers,
My re-re-reâŚinstallation was fine (the culprit was a faulty USB cable from a ST Micro development kit, handed out by ST Applications Engineers at the ST Day conference in Seattle), here are the steps and pitfalls:
(4) You may need correct arm-gcc and arm-gdb; let Debianâs âSynaptics Package Managerâ and Fedoraâs âYum Package managerâ point the correct dependencies.
(5) If possible, sit next to Peter (Thank you Peter!) who helped a ton!
(6) To flash to STMicro board, use the command:
stm32_flsh l4 ~zephyr/samples/hello_world/outdir/disco_l475_iot1/zephyr.bin
Wait for ST Micro flash to be written, you may get a message such as âUnable to match requested speed 500 kHz, using 480 kHzâ (not an error)
(7) Set screen communication (or use Arduino IDE to see the output):
screen /dev/ttyACM0 115200 (else you may see garbage outputted by ST Micro board)
(8) Press the âRESETâ button on the ST Micro board and see âHello Worldâ in the terminal (screen)!
I really like the personal touch to the instructions. It is great you
covered the challenges you faced.
This is great in the VHS BLOG along with some pictures.
When you update the blog please send a message to bpreston@linuxfoundation.org so that he can read it and share it.
Iâd highly recommend avoiding requiring OpenOCD for this Zephyr stuff - as people are experiencing, itâs tragically complicated to get running.
