RTOS/TDA3XEVM: Cache mess

Hi Alexander,

TDA3xx M4 has cache. I will ping BIOS expert to help you with this.

Regards,
Rishabh

I must give some comments... Recently I removed all cache option from BIOS cfg file. But error "Cache unsupported on device!" is still alive - from C:\ti\bios_6_50_01_12\packages\ti\sysbios\family\c64p\Cache.xs   script execution. It seemed this for ARM A8 core, not for V7M4.

Hello Alexander, 

Cache configuration is used in many of TDA3xx CCS example projects with M4.

Please refer to \ti_components\nsp_xx_xx\packages\ti\ndk\tda3xx\examples_ipu1\client\client.cfg for creating BIOS config file. Make sure you configure AMMU to use cache.

var Cache       = xdc.useModule('ti.sysbios.hal.unicache.Cache');

Cache.enableCache = true;

Also please share your config file for review.

OK!!! Finally this compiles!
I attached project to you make se is there some wrong at a glance, of course, not for long stady.

So, as I can see I must insert
var Hwi = xdc.useModule('ti.sysbios.family.arm.m3.Hwi');

in config and I may still use TDA3XX ???

Alexander,

Yes, for using interrupt configuration you should use m3.Hwi module of sysbios. This module is common for all "v7m" architecture as can be seen in "bios_x_xx\packages\ti\sysbios\family\arm\m3\Hwi.xs" file.

You can try using "Generic M4" if getting error for TDA3xx.
