Resource Share between M4 Core to Other Core in i.MX8QM

Dear All,

I am working on i.MX8QM-MEK with Android 9 Automotive.I am working on Rear View Camera.

I have following issues,

# ISSUE - 1

Rear View Camera view is being shown in full screen in Cold boot. But, Rear View Camera should have a fixed space (I configured in Android side) on screen while booting and post boot.

I don't why resource not given to other Core.

# ISSUE - 2

Sometimes while system is booting, NXP logo loading image is not being displayed (directly opens launcher application). From this screen Rear View Camera cannot be launched. This happens more frequently while we reboot the board and sometimes while we power Off and On the board.

I needs some expert guide.

Thanks & Regards,

Vinoth S,

Hi Vinoth

1. Resource sharing is described in Chapter 4 Resource Management

sc_fw_api_qm_b0.pdf included in SCFW Porting Kit

M4 Core camera example can be found in SDK_MEK-MIMX8QM,  folder ..driver_examples/isi

Welcome | MCUXpresso SDK Builder 

2. for reboot issues one can recheck datasheet requirement below

i.MX 8QuadMax Automotive and Infotainment Applications Processors

Regarding reboot I found some idea from your input.

    How to configure display will adopted for Cold boot as well as Normal android boot (post boot) ?
