Unable to connect to SKR 1.4 Turbo #3050

Closed kondas closed 4 years ago

kondas commented 4 years ago

Hello everybody. I'm trying to get Klipper working on my SKR 1.4 Turbo mainboard. My goal would be to use the rPi UART0 @ 250000 Baud, but I've tried via USB-serial and rPi UART0 without success. It looks like that after a successful flash, klippy logs are flooded with timeout messages regarding the serial connection

Wait for identify_response

  File "/home/pi/klipper/klippy/serialhdl.py", line 178, in raw_send_wait_ack
    raise error("Serial connection closed")
error: Serial connection closed

I've tried changing the usb device ID in klipper config, but doesn't help. Also changed baud from 250000 to 115200, without success. I've tried searching for issues with this board, but haven't found similar. Others reportedly using it both via USB - serial, and also rPi UART0. But i also see that their USB device descriptor is different.

Can somebody please help me what am i doing wrong? I'd love to try Klipper on my big delta.

Hi @kondas,

It did not look like there was a Klipper log file attached to this ticket. The log file has been engineered to answer common questions the Klipper developers have about the software and its environment (software version, hardware type, configuration, event timing, and hundreds of other questions).

Unfortunately, too many people have opened tickets without providing the log. That consumes developer time; time that would be better spent enhancing the software. If this ticket references an event that has occurred while running the software then the Klipper log must be attached to this ticket. Otherwise, this ticket will be automatically closed in a few days.

For information on obtaining the Klipper log file see: https://github.com/KevinOConnor/klipper/blob/master/docs/Contact.md

The log can still be attached to this ticket - just add a comment and attach the log to that comment.

Best regards, ~ Your friendly GitIssueBot

PS: I'm just an automated script, not a human being.

If you still have mention of marlin in your usb-id then you have not flashed the Klipper firmware to the skr1.4 ie from your config

[mcu] serial = /dev/serial/by-id/usb-marlinfw.org_Marlin_USB_Device_0D006023AF4A1C875D7C39AEF50020C7-if00

Hi, thanks for the comment. I also thought that, after seeing similar comments in other threads. After i build klipper.bin, i copy it to the microSD card as firmware.bin, and after the next reboot it gets renamed to firmware.cur. Since i have no explicit way to check if the firmware flash is successful, from this it looked like it is flashed correctly.

EDIT: Indeed, it is not flashed correctly, as i can see from the boot message @ serial
