LPC43XX Dual-Core notes

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

Deployment of MQX RTOs based on NXP Vybrid ARM processors

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

Install php and memcache in linux

installation: 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:

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
