Xtal 16MHz Max Jtag clock set to 1M Firmware version is V1.20
there are always 3% IC cann't be successful download, the massege is 'could not stop ARM device" . We have done the following thing to check what's wrong:
1. We reduce the Max jtag clock setting in Uvision 3 to 500KHx to 100KHz, still cannot be download.
2. we send them to manufacture and they test result is these ICs are good.
3. We send these ICs to FA(Failure Analysis) , result approve they are good;
so could you give us some advice or some analysis about it? Are there any settings in uvision can arise this problem except the max Jtag clock setting? or What else reson can arise the problem?
