Brief introductionThis page provides some basic information on using the dual-core features of the LPC43XX device. The information and topics on this page are demonstrated using the Keil UVision4 tool, using dual-core engineering. The project initializes two cores to run FreeRTOS and uses a tri-color led to indicate the operation of the M0 and M4 cores, as well as the communication between the dual-core processors. The project focuses on the details o

1). Introduction
MQX is a real-time operating system provided by NXP, with the following diagram showing the kernel, file system and protocol stack, as well as good support for NXP's arm processor, which can be easily developed and deployed.
This article demonstrates compiling and deploying MQX applications based on the Toradex Colibri VF61 (NXP VF61 SoC) Arm computer module paired with the Colibri Eva Board Development Board.The VF61 is a heterogeneous dual-core architecture arm processor that

stage, we want to use other software to replace Sendmail as the mail service, it seems that it is difficult to get close to thirst. It is imperative to upgrade Sendmail to prevent "Email Forwarding.
In view of the limited space, we will only describe the implementation of Sendmail. For details about the principles of Sendmail, please refer to the relevant documentation.
1. Obtain Sendmail
Generally, you can upgrade sendmail to sendmail.8.9.3 to prevent the email server from forwarding.

Configure scripts need to provide several kinds of information for the users who run them. The following macros print messages in the appropriate way for each information. All macro parameters should be enclosed in double quotes in the shell so that the shell can replace them with variable and inverted quotes. You can enclose messages in M4 reference characters to pri

Similarly, when I use the source code package to install the memcache source code package, I need to use the/usr/local/php5.5/bin/phpize tool to generate the configure file, the same error will be reported. From this point, it can be noted that the above two installation methods are all the same, and the principles are the same.
For this reason, I need to install the autoconf library, but when installing this library, the same error will be reported:
same.To do this, I need to install the Autoconf library, but when I install this library, I also get an error:It is obvious here that the M4 version is too low and needs to be updated. By accessing the information, Autoconf uses the M4 macro processor to process the Configure.in file, which allows the configure file to be generated for the installation configuration.Then, is to download
