My design is severely board space constrained. The latest reference manual (IMXRT1064RM, Rev 0.1, 12/2018), section 14.4.3 RC Oscillator (24 MHz) says:
A lower-power RC oscillator module is available on-chip as a possible alternative to the
24 MHz crystal oscillator after a successful power-up sequence.
I don't need precise timing in my system. I'd love to eliminate the external oscillator / crystal and use this built in circuit. Has anyone succeeded in doing this?
For the 32kHz, I don't need precision. Section 14.5.1 says:
The internal oscillator is automatically multiplexed in the clocking system when the
system detects a loss of clock.
This gives me hope that I can not use a 32kHz crystal/oscillator and be fine. Yes?
The latest reference manual (IMXRT1064RM, Rev 0.1, 12/2018), section 1.3 says:
• Support for 5-pin (JTAG) and SWD debug interfaces
Doing a search for SWD, I can see how to route the signal but I don't see any more details. Does anyone have SWD working?
Thanks in advance.
