After upgrading from AS 6.2 to AS 7.0 I’ve upgrade Xplained mini 328P firmware to version 1.0d. Everything was fine, but now when I enter device programming dialog I cannot connect to Xplained anymore. AS enumerate Xplained, so I can choose mEDBG, in Tool information I can see mEDBG with new firmware version 1.0d, but I cannot read device signature, information and so on. Any attempt to read device shows an error:
Unable to enter programming mode.
Please verify device selection, interface settings, target power, security bit, and connections to the target device. Look in the details section for more information.
In details I can see:
Timestamp: 2016-03-29 17:36:23.990
Failed to enter programming mode. ispEnterProgMode: Error status received: Got 0xc0, expected 0x00 (Command has failed to execute on the tool)
Unable to enter programming mode. Verify device selection, interface settings, target power, security bit, and connections to the target device.
In device manager I can see mEDGB virtual COM port, but nothing else. According to AS 7.0.790 readme, now mEDGB devices should “support for mass storage mode in embedded debugger (EDBG), enabling drag and drop programming”. But I can’t see any new device. But when I’ve updated my Xplained Pro SAM D21 board, I can see new mass storage device “ATMEL EDGB USB Device” as mass storage device, so I can upload new firmware.
