Today I installed the serial console connector on the Gemei x760+ and had a chance to examine the hardware a bit better. I would say that except for the buttons and the LCD the hardware is exactly equal. Same CPU, same SDRAM, same FM chip, same TV-out chip, etc.
I tried to boot dingux straight to SDRAM vÃ*a USB boot mode and everything worked, except that the kernel paniced because I had no SD/MMC card inserted and this no rootfs in place. I could see the LCD backlight blinking, so it means the same GPIO pin is used to control it.
As I mentioned in the previous post test point 1 (TP1) is the console TX signal, and I confirmed that test point 2 (TP2) is the RX signal.
So, we should have dingux runing on the x760+ in a few weeks. All that's needed is map the GPIO pins (if different from A320) and disassemble the hardware initialization code in the unbricker tool to get the LCD initialization code.
I would say the donated money has been put to good use :-). Thank you all again.
