Can this be done? For example, using the RT1015 EVK, and removing jumpers J45 through J50, then jumping wire from those pins to the respective pins on my custom board -- then using J41 (USB port) to flash from MCUexpresso? I'll probably just power the custom board from another source, while keeping a ground connection between it and the EVK obviously.
Also, can someone explain what does the "freelink" interface even do and why it's there? I assume to program, but I wanna know more dets
Hi @solderballz ,
You can remove J44-J50
J44-2->customer board POR_B
J47_1->customer board SWD_DIO
J48_1->cusotmer board SWD_CLK
Just make sure the on board RT is removed from the freelink, and connect your own board SWD to the freelink interface.
In fact, I think you also can use our MCU-LINK or MCU-LINK PRO directly to your customer board:

Wish it helps you!
