Kinetis K10 with 10MHz crystal problem

MarkP_ — Tue, 11 Oct 2011 22:24:50 GMT

Hi,
changed PE CPU configuration from 50MHz oscillator to 10MHz crystal.
CPU is Kinetis K10, configuration is K60, I think this is compatible.
Software crashes by going to reset (_boot) somewhere in function
__pe_initialize_hardware(), depends on how breakpoints are.

Found in non-PE version in function pll_init() the RAM-code workaround when
changing the CLKDIV1: fcn_ram_call(SIM_CLKDIV1_COPY);
Is this "errata e2448" still an issue with K10?
Does PE-code work correctly with setting:
SIM_CLKDIV1 = (uint32_t)0x00010000UL; /* Update system prescalers */

Processor Expert Feature version is 1.0.7.b1131-0312

BR,
Mark

Hi,
changed PE configuration:
Capacitor load: 10pF
Oscillator operating mode: "Low power"
Now works OK (crystal is 10MHz).
