Setting all 8 breakpoints

Warden Reed

Hi everyone,

I am debugging an application on a STM32F4 in flash with a ULINK.
I read one of the features for the ULINK should be 8 breakpoints, but after the 6th breakpoint I get an error message.
Isn't it possible to use all 8 breakpoints?
Maybe can I use 8 breakpoints with another device?

Can you help me with this?

    Warden:

    It simply is not possible with U-Link.
    You do need to change the content of flash memory if you need more
    than 6 breakpoints in internal flash.
    I do not know why others (below) do not just admit it,
    and instead say something like "just simulate" or "who needs breakpoints
    nowadays". If you need more breakpoints, you need an other probe.
    Rowley has something like that, Segger's J-Link seems to be best in class.
