We are using nano development board to develop our product.But we have encountered difficulties to hide command text and replace boot screen until desktop showed. We have tried some commonly used ways of linux to handle it but failed. Some engineers told me that the ubuntu os of nano is a simplified version which has been even modified of some functions.So we have no choice but to ask you about it.
In addition，I want say that in my opinion the hiding command text and replacing boot screen could be configed.But I donnot know the way on the special os system .
Look forward to your favourable reply. Thank you !
