Core is locked-up (IAR + JLINK)

Posted on August 10, 2011 at 16:26

Hello,

I got this error when I enter into a debug session using IAR 6.21 and a JLINK debug probe.

I can read the memory, it seems that the protection bytes (options bytes at 0x1FFF F800) are not in ''protected mode'' but i cannot changes them ''on the fly'' or even start the debug session, I got this error :

''Core is locked-up''

I'm not even sure I can program the memory, I thinks IAR not really program it.

I have also tried the ''unlock'' procedure from ST (seen in the PM0075 programming manual) but I can't changes the data into memory.

I add that the original source code was build under the 4.42 version and i load the workspace into the 6.21 version of IAR.

Thanks you,
