Hi Kailas

 

one can add codes for toggling some gpio in various places

of scfw and uboot, then check that gpio and measure time with oscillocope .

Hi Kailas

 

for boot times one can look at sect.3.8 Boot Flow System Controller

Firmware Porting Guide (sc_fw_port.pdf) included in  SCFW Porting Kit​
