Bootloader issue with 446

insanemal commented 7 months ago

I have a 446 and I can get it into DFU mode no worries. (BOOT0 is fine)

It flashes klipper and reboots into it fine.

But if I remove the boot0 jumper, it just doesn't work.

make flash FLASH_DEVICE=0483:df11
  Flashing out/klipper.bin to 0483:df11
sudo dfu-util -d ,0483:df11 -R -a 0 -s 0x8008000:leave -D out/klipper.bin

And after this, if I check dmesg

[ 3944.420201] usb 1-1.3: new full-speed USB device number 17 using xhci_hcd

[ 3944.538024] cdc_acm 1-1.3:1.0: ttyACM0: USB ACM device

So it's definitely booting klipper. But now if I turn it off remove boot0 jumper, it will not boot at all.

So I assume boot1 is broken?

How can I reflash it to get it all working again.

Having the same problem now...

I found my issue. It was my BL-Touch. It was connected incorrectly.

I'd try removing things from your board one at a time to see which one is causing the issue.

TotalSimplicity commented 6 months ago

Alright, I'll give that a try.

Same here but I can't find a culprit despite disconnecting everything.

When I restart in DFU mode I get another error though: Unable to write tmc spi 'stepper_z' register CHOPCONF

Really not sure what it means
