I'd really like to change the mac address on the ethernet interface as well. Looks like it's not possible unless you follow your burn in instructions above. I was hoping it didn't come to that.

Looks like support for changing the mac through software is only supported for the WIFI interfaces now :(

The distributors decide to stock on their own, the more request they get from potential customers the faster they decide to stock ;)

ARM-USB-TINY-H works with IAR EW via OpenOCD GDBserver. This product:

https://www.olimex.com/Products/ARM/JTAG/ARM-USB-TINY-H/

First start the GDB server via OpenOCD and then in IAR under Project→Settings→Debugger select GDB Server for the Driver. Then go to Project→Settings→Debugger→GDB Server and set the TCP/IP address field to the IP address of your GDB server. This is typically something like "localhost:3333". It is also explained here:

Id think the FTDI will do the full rs232; its in a box in storage unassembled so far.

  Do you sell a JTAG solution that works with IAR?  or if i search on ebay perhaps, what is the needed JTAG?  dozens of jtag this and jtag that,

Great to see a breadboard friendly RP2350B board at last!  ;D

Any word on when it'll be available from other distributors?   The €80 minimum order charge to the UK is somewhat prohibitive.

This won't work as USB-JTAG interface. You can't use it with IAR EW.

The board uses RS232_0 port for ISP programming. Some jumpers have to be configured to program it via ISP, this is explained in the datasheet of the board. In this case you you will probably need USB-RS232 adapter, it should be real RS232 not just data (voltage levels are different). Maybe ask if the FT4232HL adapter works at 5.5V RS232 (I think it only works with 3.3V RS232, but worth asking).

Thanks for your help on this.  I have this, https://www.amazon.com/EC-Buying-FT4232-High-Speed-Multifunction/dp/B0BKZ8X2C7

Will this work here as a usb to JTAG interface?  to program using the current IAR workbench?

Otherwise does the board use the usb B port for serial and programming?

or the 9pin db?

You can program the board via RS232_0 connector (this requires proper adapter cable since modern computers have no RS232 port) and programmer software. You would need to build the software to a binary and then download to the board via the programmer software and the RS232 cable.

You can get OpenOCD debugger like ARM-USB-TINY-H and configure OpenOCD environment. Search online for both and assess how hard it is.

HI thanks so much, I love learning, not a beginner but always open to learn;  I wired up an 8085, added switches, hex displays, designed from scratch, wire wrapped it, used cardboard for holding the led's and displays.  worked just fine, that was around 1986;  I got to work on mainframe cpus/systems, microcode, next address, rtl and loved it.

worked with alot of different boards, worked as a tech troubleshooting and repairing.  Took a UC extension on internet appliance design in 2000 using a board like this; never got to immerse in it like I hoped.

This wouldve been a workaround board for a place i worked, dont recall if it was IAR but they had the top license, took a week to get a key, had all the options; that was on their work laptop and  didnt get to do much at all.

so now I want to try things and learn this processor, so yes Im a beginner at this nxp chip.  Next one i need to master is the RISC V

problem is budget, the one jtag tool is $500?  Isnt there a setup thru the usb to jtag thats less? 

If the examples setup the register maps? as it looks like they do?  Wonderful, and processor type and all? 

What would you recommend for jtag debugging?  and I havent found the usb bootloader or how to maybe blink an led?  or print on the LCD by way of usb just for now?

Thanks so much
