Arduino for STM32

This kludge appeared to work:
I went into file explorer, double clicked on the "USB drive", and renamed the device "NODE_F446RE".
The name did not appear to be altered, but somehow the IDE was able to upload the program.

Bizarre!

Thanks for all your suggestions

You are 100% correct. The "C05" board in fact identifies itself as "NOD_F446RE" The IDE does indeed is trying to find "NODE_" not "NOD_".

I have tried, but I can't figure out where the latest "boards.txt" is hiding on my disk drive to edit it. Any clue as to where in the Users folder it might be ...

How would I go about altering the node name?

I could easily be completely wrong, but thought when target connected via the USB, it provides that handle/name?

The previous batch of boards, F446RE-C04, would indeed identify with "NOD_F446RE". This batch, F446RE-C05, identifies itself as "NODE ...

Hi Forum Folks,
My new batch, MB1136-F446RE-C05, A240300248 appears to not program via USB using the Arduino IDE ver 2.3.4. (Old batch -C04, loads the same program perfectly, using the same everything.) Tried three from the -C05 batch and had the same issue.

I get the error message:
"NODE ...

Just the information I needed.
Thank you so much!

I'm thinking I might be far better off putting in 7-12 volts into pin 24 of CN7 (VIN), or ~5 volts into pin 6 (E5V). Then move JP5 from pins 1-2 to 2-3 and pull JP1. I believe this will still allow Arduino IDE programming via the USB (without having to rearrange the jumpers once again.) I am not ...

I believe I have carefully reviewed the relevant manuals, including the schematic for the board:

Before I asked for a bit of guidance from this extremely helpful forum, I have spent a ...

I feel like I'm being a bit of a pest. :roll: You folks have been more than helpful so far. However, VBAT doesn't just supply the back-up for the RTC, it powers up the entire board, quickly depleting the battery when you turn the normal supply off. :-( This seems unusual to me as the typical ...

I tried your pin reassignment and it works marvelously!!
Thank you so much for your prompt reply. :-)

>> Here is what led me astray <<<<
I was misled by what is apparently a misprint in the Zephyr Nucleo F446RE web page:

I should note that SoftwareSerial does work. However, I hesitate to implement the serial port in software it as it may tax the CPU and grab a timer I may be trying to use. The proper way to do this is using the existing hardware USART. Seems like a kludge, actually.

The F446RE reads the RS-485 ...
