I followed instructions in this article.
lsusb command in my Ubuntu14.04 desktop environment shows:
Bus 003 Device 006: ID 2207:0011
But when I try rkdeveloptool with argument ld it comes:
not found any devices!
I added some code:
config.emDeviceType = RKNONE_DEVICE;
config.usPid = 0x0011;
config.usVid = 0x2207;
in the source code of rkdeveloptool project and rebuilt it. Then rkdeveloptool with argument ld works, it shows:
DevNo=1 Vid=0x2207,Pid=0x11,LocationID=30b Maskrom
But rkdeveloptool with other arguments such as td still not work fine. It puts information like creating comm object failed in the terminal.
