we have a weird issue with Atmel ICE. We have been using ICE since a while to program and debug our firmware for the ATSAM4LC8AB custom board with no problem.
Suddenly last week the Atmel ICE started to report Flash verify errors on all the boards we have available.
To check if the debugger got a problem we tried to use Segger J-Link and made an adapter up to fit the 10pole ARM debug connector. This didn't work at all, as we figured that the reset signal seem to go on the RESET pin on the 20pin Segger JTAG instead on nTRST pin 3 of the connector.
With this setup we can program the device and verify the flash short after programming, but verify later doesn't pass.
And if we using the J-Link for debugging we get messages that pointers are out of range etc.
It looks like the RESET signal is not properly handled and causes those issues.
Any idea how we could go further?
We use AS7 and downloaded the latest driver for J-Link
