L2SW initialization Error
[Check Points]
Measure the voltage at C215 (Between L2SW_3.3V and DGND). Is it 3.3V?
Measure the voltage at C224 (Between L2SW_1.8V and DGND). Is It 1.8V?
Measure the 25MOUT signal at Pin G19 of IC302 or R108. Is it 25MHz?.
Measure the TXCLK signal at Pin 23 of IC201 or R214. Is it 25MHz?
Measure the RXCLK signal at Pin 30 of IC201 or R220. Is it 25MHz?
