Hi,

Can you please elaborate on the boot flow?

What is the boot media and the SDK version?

Hi,

Could you add debug prints in bootapp on which image in the lateapp2 taking so much time. Just want to make sure it's due to Linux kernel loading.

Best Regards,

Keerthy

above，i just compare the loading time of kernel：

1、bootapp load kernel : 29.489 - 24.593 = 4.896 second

2、u-boot : 24.852 - 24.036 = 0.816 second 

while this gap huge ?

Also, consider the whole，

1、the u-boot load all image just take:  27.25.092 - 27.22.484 = 2.608 second

2、the bootapp take over: 29.553 - 15.073 = 14.48 second 

in bootapp is a step by step loading,  kernel loading doesn't affect lateapp2 loading， every loading is Independence

What boot flow are you using here?
