[ECOS] Problem configuring integrator board with ecos

[joeri_melis@agilent.com]

Hi,

We are using an ARM7 integrator board to run our software and use the following code to change the clock speed to 60 MHz instead of the default 20 MHz.

*(int *)(INTEGRATOR_HDR_LOCK) = INTEGRATOR_HDR_OSC_MEM_UNLOCK;
set_osc = *(int *)INTEGRATOR_HDR_OSC & 0x00000FFF;
set_osc += INTEGRATOR_HDR_OSC_MEM_60MHz;
*(int *)INTEGRATOR_HDR_OSC = set_osc;
*(int *)(INTEGRATOR_HDR_LOCK) = INTEGRATOR_HDR_OSC_MEM_UNLOCK + 1;

This works fine without eCos but when we combine it with an application using eCos it won't work.  We tried locating the code at different spots (cyg_prestart, cyg_user_start, in a thread function) but no changes are made to the register and clock speed.

Does anyone have a clue what might go wrong here?

Thanks, Joeri.
