Follow-up Comment #7, patch #9507 (project avrdude):

Thanks, looks good.  Commited in r1405.

Only thing: after chip erase, my XplainedPro doesn't want to
update its flash anymore:


avrdude: jtag3_paged_write(.., flash, 64, 64)
avrdude: jtag3_paged_write(): block_size at addr 32768 is 64
avrdude: Sending write memory command: 
avrdude: jtag3_edbg_send(): sending 77 bytes
avrdude: jtag3_edbg_recv():
avrdude: jtag3_recv(): Got message seqno 62 (command_sequence == 62)

Raw message:
12  a0  00  ff  
[AVR] FAILED, reason: 0xff
avrdude: bad response to write memory command: 0xa0


I think I could successfully write that board before.
