- P4: Pin 1 -> ICE Pin 1 = VTref
- P4: Pin 2 -> ICE Pin 20 = GND
- P4: Pin 3 -> ICE Pin 7 = TMS (used by SWD)
- P4: Pin 4 -> ICE Pin 9 = TCK
- P4: Pin 5 -> ICE Pin 15 = RESET
- Device: Cortex-M4
- Target Interface: SWD
- Interface Speed: 2000 KHz
- VTOR is at 0xE000ED08
- which shows vector table start now at 0x8000 (was 0x0 at boot)
- which shows stack pointer at 0x20008D10 and reset at 0x82A1 - this is for program that shipped with my board
So it looks like 8MHz XTAL * 50 / 2 is 200MHz system clock
- MPLLM[0:4] = 0, divide by 1
- PLLSRC = 0, XTAL selected (8MHz)
- MPLLN[8:0] = 0x031, mult x 50
- MPLLR[3:0] = 1, divide by 2
- MPLLQ[3:0] = 1, divide by 2
- MPLLP[3:0] = 1, divide by 2
- CMU_SCFGR @ 0x40054020 32 bits after boot: 0x00242210
- PCLK0: divide by 1
- PCLK1: divide by 2
- PCLK2: divide by 4
- PCLK3: divide by 4
- PCLK4: divide by 16
- EXCKS: divide by 4
- HCLKS: divide by 1
- Z: [10] MS1_AD0 is resistor to GND, MS2_AD1 tied to VCC
- so Z can be addressed with [10] or [11] without trace-cutting
- Y: [01] MS1_AD0 is tied to VCC, MS2_AD1 is resistor to GND
- so Y can be addressed with [01] or [11] without trace-cutting
- X: [00] MS1_AD0 and MS_AD1 tied together through resistor to GND
- so X can be [00] (R65 placed) or [11] (R66 placed)
Fix addressing (no trace cutting, just move resistors):
- remap X address to [11] by moving R65 to R66 (VCC) - TESTED - works!
Extruder driver on my board is MS35775, a 2208 clone

Sorry, I don't own the printer, just the mainboard - here is a link from someone with Kobra (but theirs is a max) https://klipper.discourse.group/t/anycubice-kobra-max-config-file/5379/6
maybe you can get some info in there that may help?
