Hi,

We are developing ADAS apps based on Linux Vision SDK (using version 3.05), can you kindly provide guideline on how to improve vision sdk app launch time from the start of a cold boot. Thanks!

Hi Simon,

here are some Linux optimization techniques:
proddms.itg.ti.com/.../sprac82.pdf
processors.wiki.ti.com/.../Boot_Time_Optimization
training.ti.com/.../sitara_boot_camp_04_optimizing_linux_boot_time.pptx

you can also look at Early Boot Late Attach feature in which the remote cores (such as DSP or IPU) are started by the U-boot instead of the kernel thus allowing to have them available earlier - see chapter "3.4 Build Linux Vision SDK for fast boot (Early boot and late attach of remote cores)" in VisionSDK_Linux_UserGuide.pdf and this wiki:
