"abstract" in order to reduce the development difficulty of DSP system software, to ensure the real-time nature of the system, shorten the development cycle, the embedded real-time operating system Μc/os-ⅱ porting to the DSP chip is a common method at present. This paper introduces the characteristics of embedded real-time operating system (Μc/os-ⅱ), and analyzes the porting method of Μc/os-ⅱ operating system in the current popular DSP chip tms320c6713
1. Install EMC host base agentmount-F CDFs-O cdcase on the client /Dev/DSK/c0t0d0/CDROM (only such a mount can read the correct EMC disc) swinstall-S/CDROM 2. Create a raid group (group 3) on the EMC Manager server) 3. Create Lun (Lun 8) on the raid group 4. Create a new storage group (js-wap01) 5. On the storage group (js-wap01) add js-wap01 to hosts (right-click js-wap01 --> Properties) 6, add Lun 8 to luns7 in storage group (js-wap01), you can see

). Based on this, the idea of writing Flash here is: after the system is reset, the program will jump to _ c_init00 and write a piece of code from the Flash copy application to the memory!Flash burning for migration to the Operating System In the previous article "general method for Flash writing on TMS320C6713", we have elaborated on how to burn bare metal code. Here we only need to make few changes to the DSP/BIOS project, the previous burning meth

Attaching is to add the separated File System to the file system partition structure. The file system must be appended to a mount point, that is, a directory. Mounting and detaching a file system occurs when the system starts and closes. The/etc/vfstab file will be read when the system starts. The file system to be mounted. Therefore, the file system in the/etc/vfstab file will be automatically mounted. You can also manually mount the file system in the command line mode. Mount without paramete

As a system administrator, we often encounter the need to increase or decrease a file system. Dynamic Logical Volume Management (LVM) is a great help for the mainstream OS and Linux on UNIX. However, Solaris Systems that do not support LVM can only be implemented in a stupid way. Assuming a work scenario, I need to add a separate file system to the server's hard drive, but there is no free space available on the hard drive. One alternative is to shrink a file system that already exists and squee
