Very helpful, thank you! Ok, here's a quickly-put-together schematic and board layout. Haven't yet done any controlled impedance or length matching for traces, and definitely need more GND vias. Will do that later, want to first get feedback to...

Note: the QNEthernet library supports zero-length UDP packets, so a better parsePacket() check would be ">= 0".

Getting better: Going from ESP32 Micromod to the Teensy 4.1 now to add sending messages to the ESP32

COOL! Glad it is working for you too! This failed to work: https://apps.microsoft.com/detail/9nblggh52bt0?hl=en-US&gl=US Now working with this "packet Sender" PORTABLE version: https://packetsender.com/download > I see you are using the same...

Had the example working yesterday but the today had an issue - so just had to rewire and it worked with your changes.

Thanks @defragster. But to clear up the problem I rewired it again and got this far - now to go hook up ESP32 or maybe a giga R1 to see if I can get them talking. But after the rewire:

Ok all a couple of things. Has anybody tried UDP an gotten it to work? Also I playing around and it keeps hanging at Starting... Starting Ethernet with DHCP... =========================== CYW4343W Card::begin: SDIO2 ===========================...

From the start: Put a tiny blob of solder on one corner pad Using tweezers position the PSRAM as best you can Reflow just that corner pad Solder the opposite corner pad; you can make minor position adjustments with the tweezers, the legs are...

@KurtE - This one: And the one I do not have is the SD card slot version: It would be nice to see if this SD slot version works with QNEthernet_WIFI on the uSDHC1(did I get that right this time?) :)

I pulled out the DB5 that has my own shield on it and am running HiLow test on it, and it is seeing other pins. Have not verified all of them, but at least some of the higher ones match... Sorry have not done a lot of testing on it yet, been...

Morning Rewired and used shorter wires for the heck of it - found I had a couple of wires shifted by a pin -- cant count :) Once I did that it started working CPU speed: 600 MHz =========================== CYW4343W Card::begin: SDIO2...

Yes, The latest is using a version of QNEthernet found here. I have not tried that library in a while. It was working. I will test it and see if there is a problem. For now it looks like there is a problem with SDIO communication to the CYW4343...

Maybe you're remembering experience with Arduino IDE 1.8.19? The old IDE has java code to give advice for certain types of compile errors. It's just simple regex and probably only works with English, but really a nice feature for those common...

Ok solved the missing file issue by giving it the whole path to the library. Once I did that I see 8 | #pragma message("Using CYW4343W QNEthernet Driver") but still getting cardCommand(341a0000, 80000402) error isBusyCommandInhibit CMD52...

@wwatson just did a double check and #ifndef ARDUINO_TEENSY41_CYW4343W #define ARDUINO_TEENSY41_CYW4343W 1 #endif and looks like its set to 1 but still get that error about...

FWIW I've tried using SDIO with jumper wires before (different project) and had a bad time. Use the shortest wires you can if you're using jumpers.

@defragster Thanks for the link - you dont have a simple scan networks sketch by any chance? > Post somewhere in thread ... :> You have to watch this line as it converted wired to WiFi: Keep getting this error...

As a FYI they have released 2.3.10

@mjs513 : seems it is this: https://github.com/wwatson4506/QNEthernet_WIFI Post somewhere in thread ... You have to watch this line as it converted wired to WiFi: https://github.com/wwatson4506/QNEthernet_WIFI/blob/main/src/qnethernet_opts.h#L12...

@wwatson Trying to catch up on this - man you all been busy. Can you post the link to the library so I can give it a try. I tried this lib https://github.com/wwatson4506/T4_WIFI_CYW4343W/tree/main but keep getting the following on the T41...

@gigapod - Glad to see your interest in this project. A little background information and the state of the project at this moment. The WIFI card we used for testing was setup for WIFI only W/O Bluetooth being broken out. That may have changed...

HI All - First - this is a awesome project with great results. Not the easiest hardware/software problems to solve! We were contacted recently by @Dogbone06 about this project and if SparkFun would be interested. Our answer is absolutely...

@wwatson Just tried using your method and its seems to work at least for the blink sketch. Have to try more later :)

Quick update: I know there is about %.01 chance of any of this stuff merging, but I know a few may want to play with it. I could not simply rebase... Could not squash commits... So I created a new branch and cherry picked...

Understood - which is one reason why my boards are sitting on the shelf and/or in boxes in cabinet...

I'm planning to merge a lot of stuff in 1.63, but variant.h support is not in the plans. Probably not the answer you want to hear, but hopefully a clear and honest answer is better than silence and uncertainty.

just gave it a try and it seems to work for me, i.e., I can leave the serial monitor open with out issue

The issue is not the code, it is the Arduino IDE not reconnecting automatically after an upload. This works with any config except Serial+MTP.

did you try and modify it to something like while(!Serial && millis() < 5000) of course you can change the 5000 to something else

:D - It is a pain, but also some interesting stuff as well. Sorry, I am also distracted, as trying to get a Pull Request into Zephyr code base, for changes to the Camera Support. I both appreciate and curse the process of getting stuff in. It...

Completely forgot about that! If I remember right I use to get a message that I forgot to select MTP Serial. Its been awhile since I played. Been playing with the Arduino Uno Q. @PaulStoffregen - please dont ever make a board like that, its...

Thanks - told you haven't played with it yet in a while. Still doesn't explain why its not working,

MTP was already added to the core library several versions ago, that's why it's not looking for the separate library.

@PaulStoffregen Been playing with 1.61.4 and decided your MTP_Teensy library (https://github.com/PaulStoffregen/MTP_Teensy) and tried the example that you posted a while ago: #include <SD.h> #include <USBHost_t36.h> #include <MTP_Teensy.h>...

Started going through some sketches and libraries So far: 1. OpenGL on mini-dev board. 2. NXPMotionsense 3 USBHost Bluetooth Joystick They all ran but received a whole bunch of warnings that I don't remember seeing some of the before. But...

If using Arduino IDE, please test with 2.3.8 or 1.8.19. Do not use the latest 2.3.9 version. A nasty bug was found where some programs aren't properly recompiled on 2.3.9. They'll almost certainly release 2.3.10 soon. Also, if you have a...

1 MB SRAM and MIPI DSI is useful for large LCD. Looks like IO ports is 5v tolerance. Only CAN FD x2. The Teensy4 has CAN x2 and one CAN FD. Shame no CAN XL.

EDIT: Perhaps NOT as first seen - the teensy-dev links seem to push it over. WORKS - with folder here as: C:\Users\_user_\AppData\Local\Arduino15\packages\teensy\hardware\avr\0.62.3\cores\teensy4 x x x x x x

That was the first that caught attention and nothing else was a problem - but SDRAM test was priority with focus. Been a while now ... If there were other 'low voltage' issues they didn't present as significant before voltage was raised and...

Ok, the repo is public again. Updated core_pins.h, digital.c, pwm.c and boards.txt. Added (-DDEV45) define to boards.txt to prevent DB4 & DB5 extened defines from being included in MicroMod defines when using a MicroMod device. Also fixed and...

@defragster - That was the answer I was looking for. I remembered that there was something that was affected by the lower voltage. So that meens the SDRAM IF is the only thing that needed the higher voltage setting? I also found a possible issue...

This. Then maybe it could be part of any Voltage change code to determine when it may be appropriate. The Industrial part on the @Dogbone06 boards doing memory tests to the SDRAM (using altered PSRAM test) is where it was observed on those...

Curious. Have we seen any issues, faults or failures in any of the industrial devices with any of the voltage or speed settings? I know the settings can affect the lifetime of the device as well as power consumption and heat generation...

There's at least two methods I know of that are likely to trigger random faults that seem to be due to brown-outs / power issues: very heavy usage of FLASHMEM functions, or high rate of interrupts with WFI instructions in between.

I really need to see a test case which reproduce the problem. This formula is far beyond what NXP says is needed, getting close to the maximum specified voltage at 528 MHz, where NXP recommends using the minimum specified voltage to reduce heat...

TD 1.62 beta 3 is working with Devboard 4 & 5 devices. I have tested 8080 parallel displays and several other devices with success. The following is the repo README.md instructions for installation found here. 1. Install arduino-1.8.19 and then...

Got curious to see what m85 boards were out there https://www.digikey.com/en/products/detail/renesas-electronics-corporation/RTK7EKA8M1S00001BE/21421315...

Looking forward in seeing a Teensy with Cortex-M85. Hope it will have plenty of RAM and peripherals.

PJRC decided to skip RT1170 and focus on NXP's next generation. I can't talk about anything I might know of NXP's future products which isn't yet published on their public website. PJRC does have a NDA with NXP, which is how we got an early...
