My company has an older product that uses an Atmel (now Microchip) AT91SAM9G45 micro that we will be required to support through 2030. Our current production programming fixture uses SAM-BA v2.11 with an Atmel SAM-ICE JTAG pod (manufactured by Segger but will only work with Atmel chips) to program the boards before a unit is assembled. Unfortunately, the programming fixture in production is having issues and will be replaced soon with a Windows 10 / 11 machine. The current toolchain is not supported under Win 10 / 11 so I am considering just using J-Link Commander to program the unit.

Using my J-Link Pro and v7.96 (latest) of the drivers and tools, I am able to connect to the processor and query it. However, I am not able to program it because the processor uses external NAND flash chips (connected via SPI) to house the Windows CE 6.0 OS and the application that runs. I poked through a bunch of the example projects that came with the tool set and found a similar Atmel chip that included sample code that also use external flash so I have an idea of what I need to do to setup the processor so the J-Link tools can write / read to that NAND flash. Is there anything beyond getting the interface setup for the NAND flash that I will have to do, like creating an external flash map, before I can get this whole process to work?

Thanks in advance for your assistance!
