With the new driver and files, I didn't need anymore the 2 seconds delay, I use again adapter_khz 6000 (with jtag_rclk 6000, the original pandaboard configuration, it seems didn't work, but these is another history :P). Moreover, it is at least more than 3 times faster (for example, the old driver need 240 seconds to transfer 3.6MB and the new between 55 and 65 seconds).
I think that this new driver must be documented in the oficial openocd documentation. I lost a lot of time with problems like I had. The cable that I am using (http://code.google.com/p/opendous/wiki/JTAG) give instructions to use with the ft2232 driver and the few people that speak about the new driver never say how to use it. The cable is similar to jtagkey, so I take its cfg file and made my own changes: >>> interface ftdi ftdi_device_desc "Dual RS232-HS" ftdi_vid_pid 0x0403 0x6010 ftdi_channel 1 ftdi_layout_init 0x0c08 0x0f1b ftdi_layout_signal nTRST -data 0x0100 -noe 0x0400 ftdi_layout_signal nSRST -data 0x0200 -noe 0x0800 <<< The first options are easy to understand, because are similar to previous driver, but I would like to know what mean the last 3? Is somewhere explained? Andreas, thank a lot for the help and also for the driver :-D RAM ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
