Secure domain firmware v9.0.0 and onward no longer supports the non-essential domain reset procedure which was used in the custom JLink reset scheme for nrf54h20dk/nrf54h20/cpuapp, nrf54h20dk/nrf54h20/cpurad, nrf9280pdk/nrf9280/cpuapp and nrf9280pdk/nrf9280/cpurad. All resets done through the ADAC interface now do a global reset instead, which as of now "kills" the JLink session. Remove the custom reset behavior as it will not work anymore moving forward. This means that "monitor reset" in GDB can no longer be used to debug the application from the start of execution. Using current tooling, it is possible to debug from the start of execution by first resetting the cores into a halted state, starting cores other than the one you are debugging and then attaching GDB. For example: > nrfutil device reset --reset-kind RESET_VIA_SECDOM > nrfutil device go --core Network > west attach Signed-off-by: Jonathan Nilsen <[email protected]> (cherry picked from commit 18250bd) (cherry picked from commit 1e841e3)
