Flashing Android 11 on VIM3

Hi @tenk.wang , I used absolutely the same steps as yours to build android-11.0.0_r31.Build completed successfully
I used the flash script from VIM3_R_AOSP_V210604 to flash images. There is no output from HDMI, and when I used command :svc wifi enable to open WiFi, it showed no wifi service.
But if I flash VIM3_R_AOSP_V210604 image, everything is OK
What’s the difference between VIM3_R_AOSP_V210604 and android-11.0.0_r31?
How can I get the source codes of VIM3_R_AOSP_V210604?

Thanks.
