Thanks for your hard work. But I found your boot did not load i915 drivers.
I got one boot img, but cannot get the i915 driver's version. Compared with Jun's 1.04b loader, only the i915 drivers update (3 files only, drm, drm-help, i915) in the extra.lmz, no others changed from Jun 1.04b.
I just verified in my computer and works well with 6.2.2-24922 new installation, which CPU is intel J1900 and Ethernet card is intel i211.
also has /dev/dri. but the hardware decoder not tested.
This driver works well, I would like to share with you.
The img link: https://share.weiyun.com/56iapul, the document name is 6.2.1, but this is work only for 6.2.2, not working for 6.2.1(I tested, IP connection lost).
