I need help with the problem that the burner cannot burn offline. [Copy link]

I used Corda's offline programmer to program the 430 chip. Under normal circumstances of the SBW two-wire system, there is no problem with programming whether online or offline. However, when the fuse is broken, a 330 ohm resistor is connected between TCK and TST of the programmer, and the software is set up according to the attached diagram, and the following situation occurs. 1. In online mode, program programming and fuse breaking can be carried out normally; 2. When unplugging the USB for offline programming, the programmer will immediately prompt that the programming is successful as soon as the button is pressed. But in fact, the program is not burned in, and the fuse is not broken. I don't know how to solve this problem. Please advise.

Is it designed so that it can only be hot-burned, that is, it can only be burned successfully when the power is on, and it will not be successful when the power is off?

No. Because the same program, without modifying the burning circuit, has no problem online and offline. In fact, the modification of the burning circuit is also very simple, just adding a 330 resistor and changing TCK to TST, which are all official operations in the regulations.
