I'm trying to get a custom board based on T4.1 up and running. I'm at the 8 blink stage:
8 Blinks = Unknown IMXRT Chip
The IMXRT chip responded, but with an unsupported JTAG ID. This error can happen if IMXRT AD_BO_08 is not connected to MKL02 PTB5, or it is shorted to GND. Software which mis-configures pins can also cause this error.
The AD__BO_08 line is not shorted. The chips seems like they are well soldered (thanks to our assembler, not me). I am using the MIMXRT1061 chip (smaller version) rather than the MIMXRT1062 chip. Do they have different JTAG IDs?
