POST
POST codes on Xbox are sent by the southbridge via I2C to an optional MAX6958 IC to be displayed via 4x 7-Segment-Displays.
I2C Address: 0x38
f.e. I2C SDA/SCL pads from FACET connector or RF Unit can be used.
Schematic
Reading POST codes
There is a minimalistic POST monitor implemented via Raspberry Pi Pico. It simulates the MAX6958A I2C Slave and displays the gathered POST-codes via USB serial.
Soldering 3 wires (I2C and GND) is necessary.
Segments indicate the error-type.

POST Codes
The following sections of POST / Error codes is not complete. It's extended whenever new codes are found. Ideally it should be in sync with Tools
SMC
0SMCBL and 1SMCBL only output their progress to the ITM / ARM Cortex debug port (SWO). Actual POST codes are output starting with ?2SMCBL?/SMCFW.

SP
Security processor also outputs POST codes but due to the lack of binaries, these are unknown so far.
2BL
2BL outputs POST codes as a combination of Phase (high-byte) and Agesa testpoint (low-byte).
If low byte == 0xFF, the phase is considered successful.
f.e.
14FFis read as0x14: Final,0xFF: EndAgesaTps04C5is read as0x04: AgesaEarlyInit,0xC5: TpAbl3ErrorDetected
