I have finished the code.
The biggest problem is the Flash Program Speed.
RM08001_JLinkUSBProtocol.pdf:
The USB latency is more of a problem. Since the host schedules USB transactions
in frames of 1ms for full speed and 125us for high speed connections, the
average latency is 2ms for full speed and 250us for high speed connections.
This means that even a small transaction of 1byte typically takes 2ms on full
speed connection and it also means that minimizing the number of transactions
to the minimum required is
desirable.
Here is the console log:

Have you tried using the SVF or XSVF support to do that?
That's the only way to do it for now; we don't have much
other boundary scan support.
