In detail,
On each STM32 chip has two pins BOOT0 and BOOT1, these two pins in the chip reset the level state determines the chip after the reset from which area starts to holdLine procedure, see the following table:
Boot1=x boot0=0 boot from the user flash, which is the normal mode of operation.
Boot1=0 boot0=1 boot from the system store, this mode starts the program features set by the manufacturer.The Boot1=1 Boot0=1 is started from the built-in SRAM, which can be used for debugging.

To learn more about router Internet access configuration, it is very important for ordinary home users and to ensure our network security. The first thing to confirm is what your "Broadband Access Method" is like? Of course, the simplest way is to call your ISP (Internet Service Provider) for consultation. You can also make a quick judgment by using the network connection method you used to buy a router. Common Hardware connection methods include the
How to adjust the basic configurations of A vro such as the fr40 vro Configuration Guide to configure a vro so that the computer can share the Internet through the vro, which is relatively easy to implement. The following content in this document, this section describes the following parts: www.2cto.com 1. Collect and judge the information to prepare for configuring the vro. 2. Enter the vro management interface and configure the vro. 3, the configuration process is simple for troubleshooting. L
Ftp commands are one of the most frequently used commands by Internet users. A large number of internal FTP commands are used in both DOS and UNIX operating systems, familiar with and flexible use of FTP Internal commands can greatly facilitate users. For users who are currently on dial-up, if the ISP provides shell, nohup can be used, ftp will be the most cost-effective method for downloading. The ftp command line format is: ftp-v-d-I-n-g [host name]
A Siebel client Configuration tool has been released since the last time. Some friends have responded that they have administrator permissions, and it is a bit difficult to manually modify the configuration file to modify the trusted site, so I have made some improvements, this is a small one.ProgramIt is small but powerful. Because of the project environment, it also provides dynamic identification of the local network ISP to automatically write the

Recently, many people are still asking how to connect to a home network or a small network. What are the methods. Here I will provide you with various solutions based on my own understanding to see which one can be used. It indicates limited capabilities. I do not know if you can understand it.
1. access the Internet from one machine (direct connection)
2. connect multiple machines to the Internet and use a Broadband Router (express Connect)
3. access the Internet from multiple machines using v

The following is a function written by the author to write values to a specific address:
Void writetoflash (uint32_t offset, uint32_t date){/* Erase before writing */Int I;
Un_lock_reg (); // when writing data to flash, it is written through the system isp. Therefore, you need to write three values first. Friends who have routines can understand this.Ispcon | = ispen; // enable the ISP Function

When using a DSL connection, if you are using a DSL connection that has a fixed or static IP address, the configuration step is the same as described in the previous network configuration. You connect the Ethernet interface to the DSL modem and configure the IP address, subnet mask, broadcast address, and gateway information provided by the ISP. You should be connected to the Internet after you restart the network device. Remember, you may also need t
the kernel stack from the interrupt stack takes place at DO_IRQ ()-HANDLE_IRQ ()-Execute_on_irq_stack ()The last function literally means executing an interrupt-handling routine in the interrupt stack, which means that the interrupt handler executes in the context separate from the interrupted process. The Execute_on_irq_stack function is implemented as:
static inline int
Execute_on_irq_stack (int overflow, struct irq_desc *desc, int IRQ)
{
Union Irq_ctx *curctx, *irqctx;

The significance of open-source tools for statistical translation must be explained. Brown and so on proposed the IBM model was in the early 1990s S, and the year of extensive use and research of the IBM Model Turned out to be after 1999! The reason for this is the emergence of the open-source toolkit! The emergence of open-source tools has lowered the entrance threshold for research, so that we can truly stand on the shoulders of gi
