Also a small question :
I have read soemwhere in the forum that Display SW needs to be updated in both QSPI and additional storage(if thats true does doing initrd flash is enough?,how can i check that everythign is udpated ?)

I have followed documentation to exceute the changes ,but i am quite new to the embedded linux ,so any help or guidance on this is much appreciatied.
