Nuvoton Nu-Tiny NUC220 firmware update problem

Followings are my detailed verification procedure.
No.1 - 5 are same as Nu-Tiny FW update.html

No. 0 and 7 - are newly added, and No. 6 is editted.

0. First of all, I'm using Tool version 2.05 build 6815.

My dialogue image of "Chip options" is different from your mail information (2018/12/6, Thu 22:05)

So, I'm afraid my tool version is different from yours.

1. Power on PC and start ICP programming tool 2.05.
    Connect Nu-Link Pro to the PC and connect Nu-Tiny NUC220 board to the Nu-Link Pro.
    Select target chip : NUC100 Series  ----> Click "Continue"

Click the "OK" button on Fig. 09 to close the window.

10.  Plug out Nu-Link Pro from the USB terminal and Plug the Nu-Tiny-NUC220 in same(or other) USB terminal.

Nothing happened on main window.
So, click "Connect" button on the main window.

11. On very rare occasions, following window was appeared.

Even if it appeares, it disappeares quickly before I click "OK".

12. Finally, the ICP Programming Tool window goes no response.(sorry, the language is Japanese.)

13. If I plug out the Nu-Tiny-NUC220 from the USB and plug it again,

the window respond once and the Nu-Link ID(ffffffff) was displayed as Fig. 13.
but the application seems no response, becaouse the close button(x) does not respond as described below.
And the "Setting" button in Config Bits section remains inactive.

Fig. 13

In that case, the CPU activity ratio(on the task manager) is very high.

When click close(x) button twice, following window("Please wait ---") appeared.

14. I shutdown the ICP Programming Tool from task manager, and plug out Nu-Link-NUC220,

then start the ICP Programming Tool again and plug Nu-Link-NUC220 in USB.
the same situation as No. 13 occures.
After I shutdown the ICP Programming Tool and plug out Nu-Link-NUC220,
then start uVision5, plug Nu-Link-NUC220, and select debug mode.
uVision5 replies "read error"(Fig. 14a), and "Error: flash download failed"(Fig. 14b)
