Looks like i bricked my NXP Rapid IoT development kit. I connected it to Hexiwear docking station, tried to flash it and now it does not want to boot up again. I tried all the recovery guidances described in Rapid IoT Prototyping Tool User's guide (pressing SW1/2/3 + reset) but it does not work. The only thing which happens after pressing SW5 (reset) is that white and blue LEDs are blinking, then light together for a while and nothing else (even the screen is blind).
Now I am trying to follow the chapter 4.1.5. (Re)Programming of K64F and KW41Z Bootloaders - 4.1.5.1. Using Segger J-Link commander and precompiled binary files and I am struggling to obtain the file kboot_k64f.bin. I downloaded the SDK, but there is only kboot_kw41z.bin in it.
I was also struggling to follow the step "From your computer file explorer, drag-n-drop or copy-paste into the MAINTENANCE drive the binary file OpenSDA_V2_1.bin" as there is not described where to download OpenSDA_V2_1.bin - finally I found it could be downloaded from the page OpenSDA / - SDA V2 | SEGGER - The Embedded Experts . Nevertheless I am lost when talking about kboot_k64f.bin. Where to get kboot_k64f.bin? Could you help me to obtain this file and get my NXP Rapid IoT kit working again?
Generally said I found the documentation very stochastic, fragmented and outdated, so the beginner with this technology is qute lost :smileysad:
