Program a new chip

[Shruti1]

Hello,

I am designing a PCB which has the mimxrt1062 chip. I am bringing the JTAG pins out. Can I connect a JTAG debugger and program the MCU from scratch, as in there is no old code on the MCU? Is there anything I need to look out for?

Hi @Shruti1,

There is no issue debugging the MCU from scratch, with no previous code flashed into it. Let me know if you have further inquiries about this subject.

Hey Edwin,

Thank you for your reply. For a RT1062,

1. What ROM bootloader can I use? And how can I program it?

2. After programming the ROM bootloader, I can flash my application, correct?

3. I would like to try this out on the EVKB board I have. I found this resource for the EVK board: https://www.nxp.com/design/software/development-software/sensor-toolbox-sensor-development-ecosystem...

Is there something similar for the EVKB board?

I currently have JTAG attached to my evk. And those are the pins I am bringing out in the PCB we are manufacturing.
