Hi @cmaier
1. Open MCUXpresso IDE.
2. Import any example of the SDK. In this guide, I imported the iled_blinky example. In the end, I will explain why you need this project.
3. Go to your RT1170-EVK and locate SW1.
4. Change to serial boot loader
5. At this point, you need to do a power-cycle to your board (disconnect and connect the power), so the changes in SW7 take effect.
6. Go back to MCUXpresso, since you just imported the project, I assume that it doesn’t have any debug configurations if you are using another project that does have debug configurations please delete them.
7. Launch the debug session of the project while in serial downloader.
8. When the debug session is launched, you won’t see that the program stops at the main as it normally does, your debug session will look like the image below. This is because you are in serial downloader mode.
9. Stop this debug session.
10. Delete the debug configuration of the project, as shown in image 2.
11. Go to your board and change the SW1 back to the way
12. Do a power cycle to your evaluation board.
13. That’s it! At this point, you should be able to enter the debug sessions without any problems.
I hope this will help you

Hi Carlos Garabito,
I started a support ticket, and got essentially the same answer, but in less detail than yours:
Please switch the board to serial download mode then use IDE or MCUBootUtility to erase flash.
Your step-by-step walkthrough is very helpful.
Filling in the details to your colleague Jing Pan's advice,
I deviated from your suggestion to launch a debug session,
but used the GUI Flash Tool to mass erase.
I wrote up a little emergency checklist that I would have found most useful, because they look familiar from flying small airplanes:
# Recover MIMXRT1170EVK from low power mode hang-up
1. Power switch **SW5 - OFF**
2. USB cable at **J11 - DISCONNECT**
3. Power cable at **J43 - DISCONNECT**
4. Serial programming mode **SDP_MODE - SET**
* according to SDP_MODE on PCB silkscreen
* SW1: 0 0 0 1
* SW2: 0 0 0 0 0 0 0 0
5. Power cable at **J43 - CONNECT**
6. USB cable at **J11 - CONNECT**
7. Power switch **SW5 - ON**
8. MCUXpresso **GUI Flash Tool - START**
9. Target Operations **Erase - Select**
10. Algorithm **Mass erase - Select**
11. GUI Flash Tool **Run... - Click**
* MIMXRT1170EVK flash will be erased
12. Power switch **SW5 - OFF**
13. USB cable at **J11 - DISCONNECT**
14. Power cable at **J43 - DISCONNECT**
15. Serial programming mode **DSPI_FLASH - SET**
* according to SDP_MODE on PCB silkscreen
* SW1: 0 0 1 0
* SW2: 0 0 0 0 0 0 0 0
Thank you!
Christoph Maier
