program runs well in ram, and the problem will occur in Flash;
The most typical function is us_delay. The latency in Ram is precise, but it is different in flash;
3. End the nonsense and go to the topic. How can we burn the program into flash when we want to have no simulator?
We look at the starting method at the top of the SCI-A boot, SCI is a serial communication interface, we can start from the serial

Recent project to use Minicom, installed on Linux after the installation, found that the Development Board and virtual machine serial port can not communicate, by looking for information, you must first set up the relevant virtual serial port-Create a web hosting pipeline.

MSComm acts as a serial communication control
Program Serial Communication Programming saves a lot of time. It is very easy to add a MSComm control to a dialog box-based application. You only need to perform the following operations:
Open "Project-> Add to project-> components and controls-> registered ActiveX controls", and select control: Microsoft Communication Control, version 6.0 to insert to the curr
When using a serial port to debug the Development Board in VMware Workstation, you may encounter some inexplicable problems. Now I will give a brief summary and share it with you. Configurations are divided into virtual machine configuration and linux minicom configuration.
The virtual machine module configuration is as follows:

Then, according to the tutorial on the RTT official website, a serial port driver is written. It was originally defined as the uart1 port, but the usart1 pin of the Board was not found. Although the stm32 can be mapped, there is still

Linux serial port cannot receive 0x11. solve the problem that c_iflag (termios member variable) is not effectively set in many popular linux serial port programming versions on the Internet, so there is no problem when transmitting ASCII codes, however, 0x0d, 0x11, and 0x13 are lost when binary data is transmitted. No.
