How can one load/debug programs in K70 DDR?

pbarada — Sun, 21 Jan 2018 18:54:13 GMT

My application is/will be too large to fit into the internal flash of a K70 and want to load/boot the application (via some small boot-loader) in DDR and execute it from there. To ease/speed development I want to allow loading/debugging the application in DDR using KDS.

How can I run a script after the target is connected and before the .elf is loaded - to setup the MCG and DDR registers that initialize DDR?

Thanks in advance!

Hello Peter Barada,

Sorry in KDS I haven't find the debugger configure file like "init_kinetis.tcl",

so I think we can initlialize the DDR on application code.

There is a guide about "Debugging out of External RAM":

Relocating Code and Data Using the CW GCC Linker File for Kinetis

->7) Debugging out of External RAM

Hope it helps

Have a great day,
TIC
