TMS320VC5471 Dual Core (DSP 5471 + ARM7)

[ayeong]

Can anybody help me on the software selection part ?

Okay, I'm pretty sure that I need the following items to start development :

1. EVM for that above mentioned processor (DSP for C5471 + ARM7)
2. Code Composer Studio for C5000

Now, do I need to get TSM470 Code Composer Studio OMAP for the above setup ?

Anywbody who has developed on that platform is greatly appreciated.

Thanks !

using linux with TMS320VC5471

use linux kernels:
uClinux
**broken link removed**
Monterey Linux
**broken link removed**
DSPLinux
**broken link removed**

Generate host (system) code for ARM7DT: use gcc
For DSP part: Code Composer Studio for C5000 w/h alternatives

WARNING!! TMS547X has huge bugs!!

This family of uControllers has serveral and grave bugs related with the SDRAM controller. If you plan to use SDRAM you only can do that configuring the uC in a 32 bit bus wide fashion.

If you plan to use only one 16 bits (most standard) SDRAM chip, you have to use it in a Big endian mode. That is not the best way of using an embedded Linux because the standard and most tested versions (of the OS and the toolchains) are in Little endian mode.

This is only an overview of some errors, I attach the whole errata sheet. Please read it carefully before select this family of devices for your project.

The errata sheet that I attach is for the TMS5471 uC but the similar errors are inside the TMS5470 and the TMS5472 (the problems are for the whole family).
