    aaditya reacted to piter75 in Rock PI 4   
    IMHO It could never work with mainline kernel.
    At first it was named "RockPi-4B" in Armbian's custom device tree and then it was renamed to "Radxa ROCK Pi 4" following Rock Pi 4's device tree upstreaming somewhere around July.
     
    At this point you could:
    use "default" image which should work fine with "libmraa" make yourself and overlay with a model change to survive kernel updates try adjusting "libmraa" to make it work with mainline kernel (and upstreaming the change) - probably by the means of verifying that "compatible" contains "radxa,rockpi4" 3rd option would be best in the long run IMO.

    Armbian uses only 1 partition. So that's not a problem. When the led blinks it should mean it's is booting. 
     
     
    I think for all RK3399 devices the baud rate is : 1500000
    Could be only for the M4 tho. Be sure to connect the correct wires. you've got to revers the data wires.  RX -> TX and TX -> RX. 
    Not all serial programs seems to be able to use 1500000 baud rate. I've used putty in the past and that worked I think? There's other posts on the forum about what program is bes for serial use. 

    The 5.3 is a mainline. Not an updated version. There is less support for this as it's not the default rk3399 kernel.

    I'll try some images an mine and see what happens.

    aaditya reacted to martinayotte in USB-TTL converter for RK3399 @ 1500000 bps   
    I've almost all my boards hooked up with either FDTI, PL2x0x but mostly CH340 and work well with all my boards, including RockPro64, RockPi, OPi-RK3399.
    The only one that bother me is the NanoPCT4, where USB-TTL RX works Ok but not TX, so I can't stop U-boot for example.
    This NanoPCT4 issue is probably due to a protective resistor R252 which is a 2K2, I will probably try one day to short that one to see if is it the cause ...
