Hello there : )
This may be resolved but I cannot find the answer in either Segger's or ST's forum.
I have set up a fresh target (NUCLEO-G491RE) via ST-LINK with expected result.
When I move SRAM1 -> address 0 it is changed in the memory view.
Now, with a J-LINK it never changes, (not after refreshing the memory view either).
I have changed the OB to initially put the main FLASH at address 0 (BOOT0 pin will not be valid later).
As ST-LINK connects this is confirmed as SYSCFG.MEMRMP is 0x1, and changes to 0x3 correctly.
The J-LINK does however starts with 0x0 and changes to 0x3 as expected.
In both cases the SYSCFG.CFGR1 changes from 0x0 to 0x7C... before so the RCC does it's work.
Any ideas?
BTW, the J-LINK Console log does not mention about any of this, no script are involved.
