connection failed - Em(04). Cannot provide power to DAP bus

[tomi3]

I am debugging some examples on MIMXRT1170EVK. But I encountered this problem and cannot  continue anymore.

I found a subject below in this forum, but could not use Flash Magic tool for MIMXRT1170EVK. Could anyone help me? Thanks a lot!

Hi,

I got the same problem, can you share how to make this work again?

Thanks,

I erased evk boot device memory using NXP-MCUBootUtility-master tool and it worked.

I have exactly the same problem, but I can't get NXP-MCUBootUtility-master to connect either, so how do I erase the boot memory when this tool suffers the same problem? It's telling me to put the BMOD pins in "Serial Downloader" mode, which is the only setting I've ever had them on!!!

[tomi3]

SW1 is set to serial downloader mode. (B0001)

Was [connect to ROM] action succeed using UART at 115200 baudrate?

[PhilP]

I tried it over UART too, but received a message saying that it couldn't find the CPU. I have since managed to recover it, with the boot switches set to "fuses" and image programmed using the i-Jet over JTAG/SWD connector. So, I obviously had a bad image, but still don't fully understand how that happened, and why this method recovered it.

Can you please, eloborate how you, recoverd the board using i-jet, i am also facing the same issue, and tried almost every solutions, but nothing worked well
