01:21.44 | vinvl961 | I need some clarity in writing a jtag driver for OpenOCD |
01:26.08 | vinvl961 | Can anuone see my msgs? |
01:27.51 | roxfan | yep |
01:32.54 | vinvl961 | the board has a LPC 43xx with CMSIS DAP firmware on it |
01:33.26 | vinvl961 | i need to write a driver which maps ther DAP commands with OpenOCD ApIs |
01:34.11 | roxfan | good luck |
01:35.47 | vinvl961 | <PROTECTED> |
01:36.11 | vinvl961 | mainly JTAG_SCAN |
01:36.33 | vinvl961 | f you can throuw light on how TDI and TMS values are generated for a scan, it will be of great help |
01:36.53 | vinvl961 | *if you can throw light on it |
01:41.22 | roxfan | you should write to the mailing list |
01:43.13 | vinvl961 | I was adviced to look at other drivers |
01:44.16 | vinvl961 | But since I am an amateur to both OpenOCD and JTAG, it is hard to follow.. there is very less documentation on the OpenOCD APIs |
01:52.20 | roxfan | yeah, the only docs are for the users |
01:52.28 | roxfan | at least there are _some_ |
01:53.39 | vinvl961 | hmm.. I will have to wait for the the replies on the mailing list then |
01:54.37 | vinvl961 | is there a way to use a signal analyzer with any of the current working drivers and alyze the signals |
01:54.58 | vinvl961 | analyze the jtag signals |
01:55.21 | vinvl961 | Do you think it is a good approach? |
02:01.25 | vinvl961 | Or is there a way to step through the OpenOCD driver code.. like the currently working onces |

02:12.16 | roxfan | it's just a program, you can debug it as any other |
