I like to share my experiences with the orangepi zero with the expansion board. First big thanks to giri@nwrk.biz for screen resolution fixes. I have an old 13" NTSC TV (640x440). My Value at address 0x1E00130 (0xb6f85130): 0x30050368. To fit the xfce4 desktop on this TV, I had too set fb0_width = 620, fb0_height = 440, and tvout -m -x 100 -y 20 to center it. This works on armbian Jessie, DietPi, and RetrOrangePi. I had problems with tvout on DietPi and RetrOrangePi not producing the desired effect but devmem2 0x01E00130 w 0x300F03CC always worked. (Once using tvout to center on armbian I use devmem2 0x01E00130 to get 0x300F03CC on DietPi and RetrOrangePi) I had to set screen1_output_mode = 14 for NTSC in script.bin I found, as did the OP, RaspberryPi video cable does not work. But I had a Roku LT video cable that was fine, The ground has to be on the sleeve not ring 2. I made no mods to the expansion board. Unfortunately, I got orangepi zero v1.4 board that has a defect that causes it to run 50% hotter than the other versions of the orangepi zero. Mine idles around 70C and goes to 80C when doing anything. Armbian constantly throttles opi down to 240Mhz to get to 68C. I ordered a heat sink if the opizero lasts that long. Starting kernel ...
