Hi,
I am unable to flash my application to the MIMXRT700-EVK using NXP LinkServer.
Hardware/Software:
- Board: MIMXRT700-EVK
- MCU: MIMXRT798S
- Debugger: On-board MCU-Link
- MCU-Link firmware: V3.172
- LinkServer: 26.6.137
- OS: Ubuntu Linux
- Power is supplied through J54
During flashing, LinkServer reports:
Error: Wire Ack Fault - target connected?
Error: Wire not connected
Failed on connect: Ee(42). Could not connect to core.
No connection to chip's debug port
Flash operation exited with code 1The MCU-Link is detected correctly by the PC, and LinkServer can detect the probe.
The important hardware observation is that the D4 red LED is not glowing. According to the MIMXRT700-EVK documentation, D4 indicates the MCU/reset status, where ON indicates normal processor activity and OFF indicates that the processor is in reset.
I also executed the RT700 preconnect script, but the SWD connection still fails with:
Error: Wire Ack Fault - target connected?
Error: Wire not connectedSupport Request
Could you please advise:
- Why is the D4 LED OFF when the board is powered through J54?
- How can I bring the RT700 processor out of the reset state?
- Is there any required reset, boot, or hardware configuration that needs to be checked?
- What recovery procedure should I use to restore LinkServer connectivity so that I can flash the application?
Hi @Aparna1,
It's likely that the power is not being properly distributed to the MCU/rest of the board, but rather just to the on-board debugger.
Is the green D10 LED also OFF?
Please make sure that the jumper position of J2 is shorting pins 7 and 8.

Edwin.
Hi,
Yes, I have verified the following:
- The green D10 LED is ON.
- J2 is shorting pins 7 and 8 .
Please let me know if any additional checks are required from my side.

Aparna

Hi,
