Klipper „usb to can bus bridge mode“ not possible with fysetc bootloader #104

Open RedFlash49 opened 2 years ago

RedFlash49 commented 2 years ago

Hi

I wanted to try the new usb to can bridge mode (https://www.klipper3d.org/CANBUS.html#usb-to-can-bus-bridge-mode) with my Spider 1.1 (with attached CAN transceiver) but only got USB errors on the pi with dmesg. Now i replaced the fysetc bootloader with the bigtreetech octopus bootloader and the board is recognized and the CAN bus works. The only disadvantage i found is that flashing with SD card is not possible anymore. Could you please check your 32kB bootloader. I would prefer to use the right bootloader.

Unfortunely not. Still „not accepting address, error -32“ with dmesg.

Screenshot that part of dmesg for me. I will have a check

Hi It was an Error in the Klipper Firmware. I updated Klipper and flashed all MCU's to the newest Klipper Firmware Version and now it works with the fysetc bootloader. To be shure i flashed the original fysetc bootloader and the firmware again and it still works. Weird, that it worked with the other bootloader.

Thanks

HiYes i have a display buts its a hdmi display connected to the raspberry.I had the spider (1.1) connected with CAN and changed back to USB. There is no advantage with CAN and i suspected its causing too much traffic on the bus resulting in „timer too close“ errors.Am 31.07.2023 um 13:22 schrieb slaesh @.***>: @RedFlash49 do you have a display too? and might answer my quersion here ? =) or maybe @GerogeFu do you know this?
