Statistics says: by far most JLCPCB quality issues are around dual-side WBO module

• most popular issue: f0 and f4 both take FW via TC2030 and both blink but no CANbus between those!
• less popular issue: f0 would not take FW via TC2030

steps to reproduce:
rusEFI console
enable verbosecan command
hit "Pause" button after a second

expected: CAN0 RX lines

2024-04-23_16_37_25_505: EngineState: CAN0 RX: ID 190(400) DLC 8: A0 00 38 27 00 00 00 00
2024-04-23_16_37_25_506: EngineState: CAN0 RX: ID 191(401) DLC 8: 54 1A 43 03 7F 00 05 00

actual result: no CAN0 RX

from qty 25 rev C boards I have at least two "both blink but no CANbus between those!"

Смотри пайку и отсутствие кз на землю и соседние ноги где-то в этой области. Также убедись что питания 5В и 3.3В есть
