DefaultISR

Hi.

I have been made a source code with NXP PCB and my company's new PCB was received last week.

S I downloaded a source code which was activated well on NXP PCB into new PCB but there was a problem.

■ Situation : during debuging, source code is stopped at 'DefaultISR'

■ Difference between NXP PCB to my new PCB : XTAL

- NXP PCB : 8MHz

- my company's new PCB : 40MHz

※ refer to Device feature summary of datasheet(51page)

■ review

1. System OSC Clock : change from 8MHz to 40MHz

1) NXP PCB : after changing from 8MHz to 4MHz, I confirmed the source code was stopped at 'DefaultISR' during debugging.

2) my company's new PCB : happened same situation. The source code was stopped at 'DefaultISR'

2. External Reference Select : change from 'External crystal oscillator' to 'External clock source'

1) my company's new PCB : The source code was stopped at 'DefaultISR'

3. System OSC Range Select : change from Medium to High

1) my company's new PCB : The source code was stopped at 'DefaultISR'

■ Component Inspector : before chagne(activation is ok)

■ Component Inspector : after(the source code is stopped at 'DefaultISR')

■ Question : What should I do if I use 40MHz?

Hi,

Probably related dividers/multipliers are set incorrectly. Check the warning messages. My configuration for 40MHz crystal oscillator is on pictures bellow.
