i have started to play / hack support with a h616 (an android tv box in = fact) i managed to get usb, sd, e-mmc, clocks, gpio to work no ethernet and axp/power controller yet but the problem i have besides not having a proper dtb (the android = image extracted one is not exactly usable because of different notation, = device names, etc) is a serial console glitch in the form of not echoing the last character typed you always need to type +1 character to get the desired input so to login you type root\n<firstcharacter of the password> and then you = get the password prompt so you type n+1 characters to get n characters sent the bug is not present in u-boot/loader just after the kernel started the uart to ttl dongle i use in the pc is good, i tested it with other = boards and works as expected the board does not have a pin header for the connection just holes and i = stucked the wires in the holes without soldering (very flimsy but still = works in u-boot) also rx works ok does anybody know how to fix the serial connection ?=
