| 08:34.43 | doc| | hi |
| 08:36.00 | doc| | ive been using a ft2232 jtag board (modified guruplug jtag module) with a mips board and openocd-git, is it normal that is is extremely slow? takes nearly 2 seconds to halt the cpu and reading memory is very very slow 57344 bytes in 3119.897949s (0.018 kb/s) |
| 08:47.34 | Weaselweb | doc|: what is your actual jtag clock? jtag_khz (or adapter_khz) |
| 08:49.04 | doc| | ive tried jtag_khz 2000, 8000, and higher values, doesnt seem to make any difference at all |
| 08:50.38 | *** join/#openjtag matthsu (~matt@61-30-10-70.static.tfn.net.tw) |
| 09:36.11 | Weaselweb | afaik ft2232 can only do 6MHz (at least my amontec jtag-key tiny) |
| 09:51.29 | doc| | so the performance i got is normal? |

| 12:51.23 | Weaselweb | no, I don't think so. i get this slow performance only with default setting (e.g. upon first connect). after setting jtag_khz 6000 halting the core is fast (<1s) |

| 13:06.19 | doc| | i dont have the guruplug any more (its very badly designed) but i remember the jtag device worked fairly quickly with that, it certainly took only a few seconds to reflash the 225k uboot image, i dont get any errors and it does seem to work slowly, do you think its possible that the device is simply no good with mips or should it work ? |
| 13:37.42 | Weaselweb | i have no experience with mips at all. I only used arm |
| 13:39.14 | doc| | npz.. ive posted to the ml |
