Jlink downloads the streaking program to tq2440

After half a day of exploration, I finally got it. Haha. Detailed steps:

First, you have to go to nor flash on the Development Board.

The data here seems to have to be input in a row. I have been playing for a long time, ah.

In this case, even if the configuration is complete, the following is the connection and test.

After the test is successful, you can burn the program.

So far.

Note that the jlink driver I use is of version 4.12. Then, because the nor flash model of tq2440 is not listed, the automatic detection flash is selected.
