The log is something like this :
Debug: 448 9210 ft2232.c:1959 ft2232_execute_scan(): ft2232 buffer
size reached, sending queued commands (first_unsent: 0xb799b944, cmd:

Error: 453 9403 mips32_pracc.c:1101 mips32_pracc_fastdata_xfer(): mini
program did not return to start

User : 455 9403 command.c:557 command_print(): downloaded 361540 bytes
in 1.035658s (340.910 KiB/s)

This behavior provokes an error in mips32_pracc_fastdata_xfer().

I described the fix, although I came to it by trial/error/instinct. I
thought that we must shift out something somehow out of the buffer, so
I tried jtag_execute_queue().

I would like to know the real explanation, though...
