When attempting to enumerate or program an ATSAML10E processsor, the J-link driver reports that "Debug Access Level is 0 (secured). For debugger connection the device needs to be unsecured". Clicking 'yes' to unsecure the device however never succeeds and the window pops up again until eventually it gives up. We have successfully flashed this processor using the J-Link programmer before without issues so we are unsure what might be different this time. Haven't had much success looking through the ATSAML10 manual either.
Below is the full output when trying to program the device through Keil uVision.
