Octopus V1.1 F446 detected but is unresponsive.

During the initial setup I have the Octopus board unrensponsive. I’ve tried to flash again multiple times but nothing to do. I’ve also tried deconnectin all the cables and removing the jumpers to try the Micro SD mode formatting an 8GB card with sudo newfs_msdos -F 32 -c 8 -v FW /dev/disk6s1 But nothing to do: I get a fixed blue led near the card but nothing happens on startup or after pressing reset button. Should I have to to reinstall this bootloader https://github.com/bigtreetech/BIGTREETECH-OCTOPUS-V1.0/tree/master/Firmware/DFU%20Update%20bootloader/bootloader with STM32 cube programmer?

Solution:
If not, the bootloader is dead, and then yeah you should try and flash it.

Post a debug zip, i won't be able to tell without one (you can download it from the sidebar in the configurator)

Did you forget to take off the boot0 jumper? It seems like it keeps resetting to DFU

In past. Now I’m trying with everything disconnected and boot jumper on only one pin

That doesn't make much sense. Take it off. The board won't boot klipper properly after a full reset when it's on. I'm guessing that's your issue it's been flashed (plenty of times), you're just repeatedly telling it to enter DFU mode each time it boots (which is often done programatically) 😄

Was just a place to keep it and don’t forget where it is 🙂

It worked 🥳

Ah so the bootloader was indeed broken. Configurator really should have an option to attempt that fix, could use Katapult for most of the supported boards too. Glad you got it fixed! 🙂

I thought you had added that back in Rat-OS 2.0 days?

woot, bootloader flashing?
blacksmithforlife
Yeah, didn't you add a default bootloader?
miklschmidt
miklschmidt4w ago
i've talked about implementing a way to flash the bootloader before, but never did it.
blacksmithforlife
Or am I really losing my mind
miklschmidt
miklschmidt4w ago
no I can't really add a "default" bootloader, it has to be compiled for and fit the specific mcu on the board
blacksmithforlife
Ok, I'm just going crazy then. This was around the time I messed up my bootloader on the manta and you said "hold my beer"

I might have actually been drunk that time, i dno 😂😂
blacksmithforlife
Anyways, you should be able to get the original bootloader from btt and others right?
miklschmidt
miklschmidt4w ago
yeah he already sorted it 🙂
blacksmithforlife
Yeah, but I'm talking about integrating those original bootloaders with the configurator
miklschmidt
miklschmidt4w ago
Only a very limited subset are published
blacksmithforlife
Seems like a simple job of using dfu to write it, right?
miklschmidt

hence the mention of Katapult which works on most STM boards as well as the rp2040 If it's the original precompiled one.. sorta, yes.
blacksmithforlife
Sounds like a good plan then Yeah, I recall asking btt for the original and they gave me the hex output
miklschmidt

Katapult needs specific mcu configuration, then compilation, then flashing (and a lot of edge case handling) Then we need to implement the interface for flashing a bootloader
blacksmithforlife
Oof that sounds like a headache
miklschmidt

yeah but it works it's not difficult, just takes time it's great for RP2040 specifically, allows you to flash initially without the stupid "mount as usb drive" stuff
