RT1060: Enabling faster flashing

If you are prototyping on the RT106x board than you are likely familiar with the process of flashing an application to hardware or dragging and dropping our demo image into the board via the usb-serial connection. By default the RT106x boards come with an LPC-Link2 probe using an OpenSDA debug probe image. Drag and drop programming is great for ease of use when deploying one of our prebuild demo images but that functionality comes with a performance cost and lack of SWO trace functionality.

If you enable LPC-Link2 mode you can expect to see roughly a 4 times increase in flashing performance and gain SWO trace functionality! To do this all you need to do is adjust two jumpers and add external power (5volt barrel plug or usb connector to J9)! Add a jumper to J42 and adjust J1 to mode 2 as seen in the following picture.

When you power cycle the board and connect it to MCUXpresso it will automatically detect the new configuration and switch the flashing firmware over for you. Another side benefit to this is that the tool will not reprogram content that is already onboard so if you are iterating on the firmware side of your project and the UI is unchanged the tool will only flash the changes in content to the hardware further speeding up this process!
