Try erasing the device? Why are you still using such an old device?

Try to erase, read, and then write. Is it because the device is aging or the programmer is faulty? You have to know this yourself.

This is an error that occurred in the middle of writing. It can't be caused by wire interference or poor contact.

It seems that there is a problem with the hardware circuit or clock. Try changing the line first. If that doesn't work, lower the baud rate.

The products of Sanwu Microelectronics, an original manufacturer of RF front-end chip design, include WIFI FEM, IOT FEM, PA and switches.

Product advantages

FEM advantages: (1) Good harmonics, eliminating the need for external filters, (2) No need to debug matching circuits, direct replacement.

Switch advantages: low insertion loss, low latency, high frequency (supports 7.2GHz)

There may be interference or the timing is incorrect. Check whether the grounding is good. If it is not good, it is easy to introduce clutter signals.

Give up 51 and switch to M0, which is much better.

Thank you all.
