Installing OrangePi_pc_debian_stretch_desktop_linux3.4.113 as you recommends me, I don't have u-boot control, and I can't change boot options (remember that I don't have a USB UART yet).
How can I make a legacy u-boot with nanda support? I've checked sunxi reference manuals but it's not clear for me.
I still see progress, your u-boot v2017-09-dirty screenshots show that the 'bootm' command supports Android images. But probably the kernel in nanda.bin needs some additional settings to boot that are not needed with the legacy uboot:
Or if you are feeling adventurous you can hexedit the OrangePi_pc_debian_stretch_desktop_linux3.4.113 image and change the uboot environment directly to match the required settings. Or if you fell less adventurous you can replace the environment (on the SD-card) with this env.bin (1.41 KB) one that I copied from my image:
First check if the uboot environment is at the same place as mine:
# echo `dd if=../OrangePiPC_C64Maxi.img bs=1 skip=17366980 count=25` 25+0 records in 25+0 records out 25 bytes copied, 0,000234257 s, 107 kB/s bootcmd=nand read 5000000
If you see the 'bootcmd=nand read 5000000' then it's probably the same (this is the first text in the environment) so then replace it with mine: # dd if=env.bin of=/dev/mmcblk0 bs=1 skip=skip=17366980 You have to rename your nanda.bin to nanda for it to work as that's the name I used.
Mine (THEC64 Maxi Pi) boots but shows only a black screen if it don't get enough power from USB power(I have mine connected to my PC via a USB HUB and forget sometime to plug its power supply in) so make sure its gets the right power otherwise it will not boot the Carousel and you think their something wrong with it (It properly does this on the real thing too if THEC64 Maxi is based on a H3 SoC, Has anyone dared to take of the heat sink yet on THEC64 Maxi Logic board or can you see what Soc it is from Linux..?)
Hi spannernick and jj0, I booted my Orange Pi "Maxi" with jj0's image. I don't understand why with my Ubuntu legacy image I can't do it. These days I won't have enought time to try more things because I'm studying a Master. I'll keep you advised with my updates.

I'm wondering, is it possible to add a audio output to the board? Or is it only thru' the HDMI? Also wondering about it, is it so similar to the Orange Pi does that not have video output also on the audio connection? Does that mean the C64 might be able to output to a rca/s-video signal?
