Hi,
With a j-link connected to a Microchip ATSAME54-XPRO using a Segger 9 pin Cortex-M adapter, the j-link is unable to halt the CPU.
Using Atmel Studio 7.0 (Build 1645), programming and debugging this board is possible via Atmel's EDBG, and other ATSAM family parts work fine with the J-Link and AS7.
Microchip support duplicated this and suggested advising Segger of the issue.
I have tried Segger firmware/DLL versions from 6.16 through 6.22f, and I have tried removing the four isolation resistors that isolate the EDBG CPU.
I've attached two log files, one with AS7 establishing a connection and attempting a chip erase, and the other is a jlink.exe session log showing failed reset attempts.
Thanks,
-Dave
