yes, I known it

for L5.10patch last update in Jan 4th until now this patch only for single camera use case

not apply multi camera use case. Both L5.10 and L5.4 patch missing multi camera use case protect

please update the patch like L4.14

[Zhiming_Liu]

If you are using multiple camera in L5.10 , you need also apply the 0002& 0003 patch in 4.14.98.

[xu_ji1]

I know it, but L4.14.98  0002&0003 patch not suitable for L5.10

there is many build error,please check it and provide patch for L5.10

Yes, we test on 8QXP MEK board with  L5.10.72 release reproduce the ISI overwrite issue
