No Debugging when running from external DDR RAM (MQX 4.0.1, CW10.4)

[friederschrempf]

Because my application on the TWR-K70 needs a lot of RAM, I wanted to switch from internal SRAM to external DDR-RAM by using the predefined build and debug configurations. No matter what project I run, it works correctly, but I can't use any debug utilities. The watched variables all contain "0xbabababa" and the TAD plugin only gives me the error in the attachment.

Can somebody tell what might be wrong?

Thank you!

Ok, I found the solution myself. In the memory map file (PROJ_DIR/Debugger/MK70FN1M0.map) I replaced

reserved     0x60000000 0xDFFFFFFF          // Flexbus for external memory

with

range          0x60000000 0xDFFFFFFF 4 ReadWrite          // Flexbus for external memory

to enable DDR memory.

Hi. Frieder,

thank you very much for your solution that it has helped me a lot. Only a clarification: the correct file name of the memory map file is K70FN1M0.mem.

Best regards
