I tried to boot Linux on Ti60F225 but it hangs. I am using efinity version 2022.2

rohaya2021 commented 1 year ago

I am using the latest bitstream (2021.05.6)

Hang at which part? Also check the jumper setting for Ti60F225. https://github.com/Efinix-Inc/br2-efinix/blob/main/docs/setup_development_board.md#setup-ti60f225

Try use snipping tool in Windows or Ubuntu Screenshot to take the screenshot

Try to press CRESET at SW2 a few times and see if it still stuck at same output prompt.

rohaya2021 commented 1 year ago

SW2 or SW3? I press SW2 a few times still got message can't get kernel image.

rohaya2021 commented 1 year ago

It still doesn't work. I also try pressing SW3 many times. The final message was it can't get the kernel image.

Seem like it's not detecting the sd card. Check the connection of the sd card? What is the board version? Ti60F225 Rev A?

rohaya2021 commented 1 year ago

Ti60F225 I am not sure what Rev of the board.

efxmnalim commented 1 year ago

It should be on the devkit. Next to USB type C port

rohaya2021 commented 1 year ago

Ti60F225_RevA2 RevA2

rohaya2021 commented 1 year ago

I changed my SD card to a new one. Still it can't read the kernel image.

efxmnalim commented 1 year ago

Try recompile the Efinity project from this repo for Ti60F225 and program the board again.

rohaya2021 commented 1 year ago

I forgot to exit minicom properly. Now /dev/ttyUSB2 is not recognized. Can you advise how to retrieve /dev/ttyUSB2 so that I can rerun minicom again? Thanks

rohaya2021 commented 1 year ago

Please ignore my previous question.

rohaya2021 commented 1 year ago

I am able to load Linux after changing to a new Ti60F225 board. May I know what is the best way to shutdown? Is it poweroff or can you suggest another command?

rohaya2021 commented 1 year ago

Or can I leave minicom by typing exit command?

efxmnalim commented 1 year ago

Currently shutdown and reboot command are not supported. You can give shutdown command but the board will not power off.

rohaya2021 commented 1 year ago

May I know what is the best way to exit from minicom? Can I just leave with command ctrl + a + x or need to properly shut down by typing command poweroff first?

efxmnalim commented 1 year ago

You can type shutdown first then exit the minicom with ctrl+a+x. But, the board will not power off. So you need to turn off the switch on the board.
