    Paul, does the above apply to the Teensy 4.1 as well? I have been using arm_set_clock() in my main project running on a T4.1 for almost a year, and haven't once experienced/identified any negative effects related to...

    The three IPs in the TimeNTP example in the Time library examples all return no response for me, too. This one worked: IPAddress timeServer(132, 163, 96, 2); // time.nist.gov

    In my experience (and others, who took this issue up with the FNET author), the DNS lookup code in NativeEthernet/FNET will not return a host IP if the lookup is done on an alias (CNAME). To establish the IP address,...

    Yeah, what indeed could go wrong? :) One thing, if you currently use 2.54mm headers to attach the Teensy to the PCB, the Ethernet ones are smaller pitch and size, so just ensure the ethernet male/female header combo...

    As TX and RX are independent from a signaling/functional perspective, I don't think their relative lengths matter. I have a custom board with a Teensy 4.1 and Ethernet amongst other things (designed in EasyEDA too), and...

    Update: it is dns.getHostByName(host, remote_addr) in the client.connect() method that fails to resolve the address for the server. "api.weather.gov" is an alias (CNAME) and it appears the dnsClient cannot resolve...

    What errors do you have at runtime? I have had a similar experience with "Fastest" in the past, after adding a small amount of new code to a functioning project and executing on the Teensy, it would freeze/lock up for...

    Thanks Frank! Wish I had seen this thread earlier :) Last week, I was experiencing similar issues inside a loop that "normally" took around 22ms for ~500 iterations, experiencing "freezes" every 50 or 60th iteration for...
