J-Link problem with access breakpoint Опции

[Gyoergy Dozsa]

Setting access break point slown down the program execution in target with message:
Application does not run in real time because of conditional breakpoint(s) !
But, preakpoint is unconditional:
BS Write I2CCount, 1
Problem is in debugger, because this works fine udner CrossWorks.

I think you gave not enough info to clarify the problem. What MCU and what software do you use?

common measures:
Get the latest update for J-Link from segger web site. Replace the driver, used by software caused the problem, with the latest segger update.
Remove flash breakpoints in j-link driver options, also remove all breakpoints of your application... Setup only one breakpoint and try to debug again..

Sorry for my english. I know russian, but not have keyboard for it.
Thak you for replay!
Software is Keil ARM 2.42, uP is LPC2123, driver for Segger is newest.
Under CrossWork all work fine.

Ok.

Software is Keil ARM 2.42, uP is LPC2123, driver for Segger is newest.

В Keil'е бывает "залипают" точки останова. Попробуйте выполнить команду - "kill all breakpoints" (Ctrl-Shift-F9). И все же прошу уточнить, прописали ли Вы в настройках RDI драйвера в Keil путь к установленному новейшему драйверу segger'a (Segger folder\JLinkRDI.dll)?

Для устойчивой работы с LPC2123 установите JTAG speed 1000 khz в настройках RDI драйвера.
