Project Start
Worked for 1 sec

I started the full wiring pass and made real schematic changes, but I’m blocked now because there are no available ACUs, so I can’t continue executing mutations or ERC cleanup.
What was completed:
- Added support passives for USB VBUS, eFuse, AP63203 buck, isolated power filtering, LDOs, MCU decoupling, isolated I2C pull-ups, SRC4392 decoupling, clock decoupling, reset, and AES3 termination.
- Wired USB-C VBUS/GND, USB D+/D− with ESD, CC1/CC2 to TUSB320, TPS25210 eFuse, AP63203 3.3 V buck, and TUSB320 power/config/I2C.
- Datasheet check found an important correction: AP63203 is fixed 3.3 V, so the added FB divider must be removed and FB tied to the 3.3 V output sense.
- Datasheet check also confirmed RT1024 needs internal DCDC support: 4.7 µH inductor, 33 µF output cap, and delayed DCDC_PSWITCH assertion.
Open items:
- Remove AP63203 FB divider R4/R5 and tie U5 FB to 3V3_MCU.
- Change AP63203 inductor L1 from 2.2 µH to 3.9 µH.
- Add/wire RT1024 internal DCDC parts and 24 MHz MCU clock source.
- Finish MCU power/reset/debug, isolation barrier, SRC4392, clocks, AES3 transformer/XLR wiring.
- Run ERC and fix both electrical issues and schematic-wire collision/label cleanup once ACUs are available.
Continue, decide whats to do

I’ll continue from the partial wiring, make the necessary regulator/MCU corrections, complete each functional block, then run ERC and iterate until only intentional warnings remain.

Received notification from "AES3 USB Schematic" that it finished — picking the work back up.

The schematic executor completed, but I can’t inspect/reconcile its report or run the independent ERC verification because no ACUs are currently available.
Current state:
- The full-schematic completion task was dispatched with the fixed isolation, dual-clock, power, MCU, SRC4392, and AES3 requirements.
- The executor reports completed, so its changes should now be present in the project.
- Still required: independently inspect the committed wiring, review remaining ERC findings, verify no accidental isolation-barrier connection exists, and confirm clock/I2S timing and AES3 termination before proceeding to PCB layout.
