Hi,
with my “RockPi S D4PN8” I successfully entered maskrom mode. Green LED is permanently on.
[manjaro@manjaro ~]$ lsusb | grep 2207
Bus 003 Device 006: ID 2207:330e Fuzhou Rockchip Electronics Company
[manjaro@manjaro ~]$ rkdeveloptool ld
DevNo=1 Vid=0x2207,Pid=0x330e,LocationID=30a Maskrom
[manjaro@manjaro ~]$ rkdeveloptool db ./rk3308_loader_uart0_m0_emmc_port_support_sd_20190717.bin
Creating Comm Object failed!
(The error message is badly designed because a hint about the reason is missing.)
I also tried the last command with a leading “sudo” but there’s no difference.
First I tried on an USB 3.0 port, now I plugged the mouse to 3.0 and tried the RockPi on the USB 2.0 port, LocationID changed to “306” but again it leads to the same error message.
I have an identical second RockPi S and I also tried with it now but the error is still the same.
Please, what else can I try?
RockPi S, rkdeveloptool: “Creating Comm Object failed!”
rkdeveloptool db
You need to add sudo
Thanks for your reply, Jack!
But I’m sorry, I already tried
- with sudo
- with two different (but identical) RockPi S
- with two different downloads of the .bin file (sd5sum is identical)
- with two different USB ports (3.0 and 2.0)
and now I have no more ideas 
The version number on the board is “ROCK PI S V12 20190910” respectively.
Up to now I did use version 68 of the tool.
Just compiled version 69 (but the same error appeared):

(Sorry, it’s English and German mixed up. My time for it is running away for now. Will have to go on after some time.)
To the Radxa team: Please think about making the error message more precise.
Try to perform this command from root before using rkdeveloptool:
echo -1 > /sys/module/usbcore/parameters/autosuspend
It helped me to avoid the same failure on Dell laptop under Ubuntu 20.04.

Thanks! I’m trying to write the bootloader to the SPI flash of my Rock 5 Model B and this worked.
