First of all, Shawn, thank you!
Like others who have posted, I'm not new to micros but new to Ethernet and going up the (steep) learning curve.
I'm doing this for an automotive Ethernet need and have confirmed the target is four wire full...
Arduino IDE 2.3.8 with Teensyduino
Unlocked Teensy 4.1
Teensy 4 Security
Generated a key
Ran the write fuse sketch (ended in blinking red light so failed)
Compiled and uploaded both .hex and .ehex outputs and the board runs just fine...
Once I realized that the code is coping what is on the SD card to the top of unused onboard flash then copying the data from the top of the onboard flash to the bottom or external program portion of the onboard flash it made perfect sense that...
I've done a quick search of the forum and Teensy_Teensyduino page and did not find any mention of updating application firmware in the field via USB MSC or SD card.
By chance has there been any work to use either MSC or SD for in field updating...
Thank you Mark.
I've got the pre-compiled executable loading and working. Next is to work my way through converting my program's compiled results into a uTasker acceptable entry file for the conversion process. IIUC, this requires linker file...
BTW, after starting down the very dark rabbit hole of getting MCUXespresso up and running using NXP's own MCU-Link in circuit debugging tool I'm really starting to appreciate the Arduino's environment for very quickly getting a particular piece...
I did nothing apart from the simplest of Arduino sketches using one of the readily available CAN libraries. I did zero in the way of hardware configuration.
I'd like to look at the uTasker project's ability to add field upgradability and protected code to a very simple CAN communication project I'm working on. There is a bit of detailed knowledge necessary to run upload software that interacts with...
I'm completely new to the Arduino environment and Teensy yet, by following guides on this page, I was able to generate a CAN1 - CAN2 passthrough with mirror of either CAN1 or 2 reception to CAN3. I've tested at SavvyCAN PC playback speeds with...
