IMX8M Plus Display logo during kernel （Android11_2.6.0）

vachlan — Tue, 09 May 2023 04:09:26 GMT

Due to the BSP（android11_2.6.0） package being by default IMX8MP_ USES_ GKI =true。
Display drivers are loaded after kernel startup，Causing inability to display logo during kernel startup。
I will use IMX8MP_ USES_ GKI=true commented out, there was a GPU error as attached.

Please advise on how to correct the errors in this section。

Are you using the NXP i.MX8MP LPDDR4 EVK board?

Yes, I want to do that. But first of all, I want to display the logo in the kernel in this BSP

Thank you, I have read these two links you sent (which I plan to follow up on). May I ask if the IMX8MP_ USES_ GKI=true commented out。 Can GPU errors be corrected?
