Hi Xiaofan, Notice to switch of JLink power to check operation of vanilla / patched version. JLink remembers last selected interface (at least untill switched off),
The most interesting right now is patch operation with V7. Taking special care of V7 may introduce a bugs in future, when someone decide to implement SWD. Such specific should be avoided whenever possible. I wil split the patch into two parts: basic V8 and special care of V7 so we can decide to merge any of them. 2012/5/27 Xiaofan Chen <[email protected]>: > On Sun, May 27, 2012 at 12:25 PM, Xiaofan Chen <[email protected]> wrote: >> On Fri, May 25, 2012 at 10:13 PM, Xiaofan Chen <[email protected]> wrote: >>> On Fri, May 25, 2012 at 5:39 PM, Xiaofan Chen <[email protected]> wrote: >>>> On Fri, May 25, 2012 at 3:08 PM, Alexander Osipenko <[email protected]> >>>> wrote: >>>>> Thanks Liviu for valuable comments! >>>>> >>>>> I have pushed patches to gerrit, and check them on fresh branch. >>>>> >>>>> http://openocd.zylin.com/666 >>>>> http://openocd.zylin.com/667 >>>>> >>>> >>>> Great.
