document diag pin usage for stallguard

please give clear instructions on using stallguard on this board.
The diag pins seems to be shared, PA3, PA4 but when I jumper diag pins, PA3 PA4 are still working as endstops so this is confusing.
could you please share working configs for stallguard of both UART and SPI steppers.

The following is what I thought should work with Happy-Hare but it doesn't - The limit switch works but stallguard doesn't (or it ignores SGT setting) :

[tmc5160 stepper_mmu_selector]
cs_pin: mmuv2:PC7 #motor2
spi_bus: spi1
run_current: 0.4
hold_current: 0.2
interpolate: True
sense_resistor: 0.075
stealthchop_threshold: 100
diag1_pin: ^!mmuv2:PA4            #motor2 diag pin - also an endstop with nothing plugged into it.
driver_SGT: 3 # -64 -> 64

[stepper_mmu_selector]
step_pin: mmuv2:PD2
dir_pin: !mmuv2:PB13
enable_pin: !mmuv2:PD1
rotation_distance: 40
microsteps: 16                               # Don't need high fidelity
full_steps_per_rotation: 200        # 200 for 1.8 degree, 400 for 0.9 degree
endstop_pin: ^mmuv2:PB2.         # Selector microswitch
endstop_name: mmu_sel_home
#
# Uncomment two lines below to give option of  selector "touch" movement and homing
extra_endstop_pins: tmc5160_stepper_mmu_selector:virtual_endstop
extra_endstop_names: mmu_sel_touch

if the limit switch is unplugged, stallguard works, and if its plugged, it doesn't.

Any insights would be appreciated.

Repo should include mounting brackets

For example, here's a mounting bracket I made specifically for ERCFs with the Sturdy Bunny mod, but it'll attach to any extrusion.

I made it public domain so please use it if you'd like

Please add JST XH3 instead of 2.54 Jumper to the box

Why are 15x 2.54mm Jumper in the Box?
Please add 15x JST XH3 and Metal Pins for the endstops etc.

Katapult "make flash" does not exist. STM32 programmer fails

Katapult does not support the make flash command.
Attempting to use STM32CubeProgrammer results in errors and unable to flash.

BTT sent me 5160 drivers and I don't know how to configure them.

Can you provide and example of 5160 with stallguard?

Canboot is now katapult

In the manual https://github.com/bigtreetech/MMB/blob/master/Hardware/BIGTREETECH%20MMB%20CAN%20V1.0%20User%20Manual.pdf it refers to canboot and "https://github.com/Arksine/canboot"

The link is now https://github.com/Arksine/katapult it would be wise to reflect that and also warn in the manual that canboot is rebranded as katapult to avoid confusion

Wrong Pins

Im on build a ERCF with your MMB-Board and found 2 wrong declared pins, Ive fixed it in the following pic (red arrows)

Documentation needs to be improved around function of CAN vs. USB vs. HVIN

It is very unclear that you MUST use the CAN connector to power the board and cannot use the HVIN + USB connectors alone.

For future readers, here's how the various connectors work for real-world usage:

If you're flashing firmware, you can connect just USB with the VUSB jumper in place. >>> Be certain to remove the VUSB jumper before connecting any power or CAN cables <<<
If using CAN as a communication interface and you don't need extra juice for the steppers, just connect the CAN plug
- Set each stepper voltage jumper to VIN
- If your mainboard supports CAN but you otherwise don't know what to do, this is probably the option you want
If using CAN as a communication interface and you DO need extra power for the steppers, connect the CAN plug and also connect your additional power leads to the HVIN and GND
- Set each stepper voltage jumper to HVIN
If using USB as a communication interface and you don't need extra juice for the steppers, you have to connect the CAN plug and put 12-24v through its power leads. You then have to connect a USB cable from your printer to the MMB
Set each stepper voltage jumper to VIN
- If your mainboard DOES NOT support CAN but you otherwise don't know what to do, this is probably the option you want

CAN bus wiring with EBB SB2209, U2C, and MMB

What is the preferred way to wire the CAN bus when you have multiple devices? In my example I have the SB2209 tool head board connected to my pi via a U2C adapter. What order should the three devices be in the bus and which ones get the 120R resistor jumpers?

Voltage selection pins

Please properly indicate the voltage selection pins of what voltage VIN/HIVIN is and that they are required for the motor to function
