I am trying to design a new pcb for my project. I have nearly finished a design for the atsamd21 but was looking in to see if the MK20DX256 would be a better choice. I first looked into how you bootload these things, as people have had issues with bootloading the samd21 and i was seeing if it was easier/harder.
I couldn't find much but by looking through the datasheet (which I find rather vague and unhelpful) it says it has a JTAG to SWD port and so I thought I could flash the bootloader with the Jlink edu mini just as I planned to do with the samd21.
I was wondering if anyone has any experience with the mk20dx256 that could lend me some advice.
Any response is appreciated. Thanks in advance, Sean.
