QN9080 remove external XTAL osillator (16/32MHz) problem

[wang_barry]

Hello,

     We used 9080 to develop our product. 

     We try to remove external 32k & 32M crystal oscillator. (only use internal oscillator).

     But We can't program image through LPC-LINK2 or ISP when we remove 32M crystal oscillator.

     Question:

        1. Can we remove the 32M crystal oscillator without affecting MCU work normally.

        2. if yes,  any suggest for  program image program

Hi,

Hope you are doing well. The internal 32M oscillator is only used to system startup, not intended for peripherals.

You need the external XTAL in your design.

Best Regards,
