We're trying to integrate the RT117x series into our established development environment, that being GCC and GDB on Linux.We're facing some issues, as the articles describing the setup of the RT117x Eval board are for windows:
We're able to flash our own programs using DAPLink ontoQSPI. We now want to flash and debug using SWD. We're unable to get the GDBServer to connect to the target. The board is not modified, the SW1 is on [0,0,1,0], the SW2 is [all zero]. I have the following output when using a J-Link BASE:
$ JLinkGDBServer -endian little -noir -speed 4000 -port 2331 -vd -device MIMXRT1176xxxA_M7 -if SWD -halt -reportuseraction -JLinkScriptFile evkmimxrt1170_connect_cm4_cm7side.jlinkscript

Please check power, connection and settings.
Can someone point me in the right direction, if we're having an incorrect GDBServer setting or some setting on the board is incorrect?
