Expected/description: I think gdb can do flash everytime.

Could you try a little older commit from the master branch? Probably there is something wrong with the flash locking/unlocking.

[master-q]

O.K. I'll try that. Please give me some times....

I'm having the exact same issue on v1.6.1

@Ant-ON Can you check this one as well? I think though st-util was used, this may also be addressed by #1113.

[Ant-ON]

@Nightwalker-87 Old error descriptions are not informative. Most likely this issue is closed by #1113.

[Nightwalker-87]

Yeah, true. However, as the error code

2017-05-20T17:04:13 ERROR src/flash_loader.c: flash loader run error
2017-05-20T17:04:13 ERROR src/common.c: stlink_flash_loader_run(0x8000000) failed! == -1

is identical to what we've seen before one should be safe to assume the issue is fixed by now.

[Ant-ON]

@Nightwalker-87 Yes, otherwise someone with the error can open a new issue with a new log
