Hi Apollox80,
First of all, I suggest you to check the power source of your target board. As you know, inDART-One could provide the power for the board, so, please make sure you have a separate reliable power supply for the standalone mode.
Secondly, about the internal clock setting, I suggest you to refer to the example project in CodeWarrior. You could easily open the project by the "Startup Dialog"->"Load Example Project" and select "RS08"->"Evaluation board"->"DEMORS08KA2". For your ease, I paste the relevant code segment for your reference.
Code:;CONFIGURES CLOCK (FEI Operation Mode) mov #HIGH_6_13(NV_ICSTRM),PAGESEL lda MAP_ADDR_6(NV_ICSTRM) sta ICSTRM ; Sets trimming value clr ICSC1 ; Selects FLL as clock source and disables it in stop mode clr ICSC2 ; ICSOUT = DCO output frequency wait_clock: brset CLKST,ICSSC,wait_clock ; Waits until FLL is engaged
I hope it helps.
