 This is the first success of getting a tester going for the Metro M7 here. I'm using a Raspberry Pi and thankfully there's a built-in ROM bootloader into the IMX RT series and SDP host which is like the software you can use to talk to the ROM bootloader is available for the Raspberry Pi so I can use that to load test code. I have a program that I run on it that lets me program the onboard ESP32 co-processor and then I wrote you know kind of like a mini Arduino implementation where I can like do digital write and digital read so I can test all the GPIO on here and then when it passes it says test okay so about you know 26 seconds to get a board running and it even has a little neopixel swirl when it succeeds which is great so I'm like one step closer to getting this tester completed and these boards into the shop.
