Hi,
I didn't try the patch per se but I put the jtag_add_clocks() call
in the fastdata for loop. Hardcoding the number of clocks.
My major concern at this point is seeing what's the max download speed
we can get out of openOCD.
With the code changed to call jtag_execute_queue in each
mips_ejtag_fastdata_scan I was seeing download speeds of 2k/sec.
The adapter_khz setting seemed to make no difference.
I guess you are using the old, now deprecated, ft2232 driver. And
probably, in the adapter configuration file, ft2232_latency is set to 2.
If that's the case, change ft2232_latency to 1. At least the transfer
speed should be near 4k.
Please try to use the new ftdi driver.
Thanks
Salvador
