I am experiencing excruciatingly slow programming times on the SX-ULPGN-EVK board. I'm using the FTDI Chip C232HM-DDHSL-0 JTAG cable as recommended by Silex Technology. I'm getting data rates of ~200 bytes/second. Programming the QCA4010 with a 1015808 byte image takes about 1 hour 30 minutes. This is not acceptable.
I'm using the exact version of Ubuntu and FTDI drivers as specified in the SDK release notes.
What transfer rates should I expect? Is the FTDI cable known to perform slowly with xt-ocd? Will a different JTAG adaptor perform better? Is there a known problem with the tools from Cadence?
