keil5 compile success but load fail
Error information and related set up are as follow:
command not supported
I need your help, thank you!!!!QWQ
You had J17, seem to recall J34 being current.
The serial number looks invalid, suggesting you have a clone/boot-leg device.
What does the pop-up error actually say? Does the ST-LINK Utility work externally from Keil?
Custom board? Has it's functionality actually been established?
The L4 also sometimes has dual/single bank flash configurations, requiring the appropriate flash algorithm to be selected.
solved!!! Thank you very much!!!
