Once, the inner belt of the front wheel of the bike broke, so I replaced it. Later, the bike was retired. I bought a second-hand one. The outer belt of this bike was older. Yesterday evening, when I w...
The Cortex-M architecture uses a "vector table lookup mechanism". When an exception occurs, the kernel will automatically find the entry address of the handler from the vector table. The vector table ...
After compiling C and C++, I use Trace32 to trace. How can I display the corresponding C and C++ codes in trace32? Now it can only display C code. How can I debug and display C++ code? Thank you!!!!...
The top module has only one input clock , but I want to use it as the input of the DCM and use it to count the delay to control the reset of the DCM. If I use it directly, an error will be reported du...
