I have prepared a patch , but reserve a puzzle . Need to find hdmi-tx node address then change it in device-tree to get video output.
Some H6 board using RGB port to connect display. from one board I have ,it using RGB port (PD0-PD21) connect Ti DLP3435 , so to support that board ,it need mainline support RGB Display output , then use i2c send some command to dlp3435.(Vendor kernel using opt3435 driver to do that but I can't find source code, only firmware provided)
But now mainline currectly not support RGB output . although it support ,it will also encounter a conflict problem. rgmii phy(RTL8211) share the same pins with RGB port (PD0-PD21).
Anyway , I guess support this type board Display need a long way to go .
Your board could be supported, but first somebody (most likely you since others probably don't have interest in your box) have to submit board support patches to U-Boot and Linux. As soon as there is general consensus that they're ok (that can be before they're actually merged), I can add support for it here. If you want help with this, I can coach you, since I'm reviewer for Allwinner Linux patches and U-Boot contributor.
Thanks for your reply, But in fact this model also have lot's of variant ,you can think this is a sunvell r69 , can using beelink_x2 image out of box . but some of them using LPDDR3, so need replace self-compiled u-boot manually.
also, I even found some tanix tx6 variant board using LPDDR3.
So, for these mess variant board , will manually compile and replace u-boot for temporary solution.
found a H3 tv box , it seems like a stripped sunvell r69 , using xr819 wifi , but have a LPDDR3 memory.
It can use beelink_x2 uboot but with CONFIG_SUNXI_DRAM_LPDDR3=y and CONFIG_SUNXI_DRAM_LPDDR3_STOCK=y in config
If LE can support this board would be much appreciate.
Will the H6 get RGB LCD support ? Just found a H6 board with RGB LCD ,but without HDMI port. this board also have a I2S codec(NPCA110B) for headphone jack and speaker.
I got a MGV2000 with gxlx_p261_1g board. CPU is S905Lv2 (or maybe S905L-B but not S905L2)
and i extract dtb files from android boot.img
hope it can helps
