Download code in ram

Lorenzo Niceforo

Hi to all,

I updated an old project from Keil 3 to Keil 5.21.1.0 and i have a problem to test a part of code that must run in RAM

i am using jlink

I try to explain:
My main code in internal flash takes a cripted code that is in SD, loads it in internal ram and executes it. All seems to run fine (it worked with keil 3)

The problem is that i can't understand what to do when i want simply debug
For example: i want to download the code in internal ram and then start the debug of the main code in internal flash

with keil 3 i used the DownLoad command in the Flash menu to download in ram and all was fine
in keil 5, keil asks me for an algorithm (that is useless because in ram)
i already put a reference to an external ram.ini file in Debug and Utilities tabs of Option window with the code

LOAD %L

when i use the start/stop debug session no problem, but when i want simply download in ram there is the problem

Load "F:\\Sviluppo\\Trasdata_v3_Keil5\\Loader\\Progetto\\FP0103\\Obj\\FP0103.axf"

so how i must set keil 5 to download a code directly in ram?
or what is the right way to download code in ram?
