Hi,
I'm using OMAP5432 board for my project. I'm facing an issue that I'm unable to add cache memory in my config file. When I try to add I'll get an error message "Unicahe not supported on device". I've seen a similar thread in forum. The solution given was to add device table entry for 5430 in hal/unicahe/cache.xs ,but that didn't solve my problem. I need to enable cache as it seems to have a huge performance hit.
Thanks in advance
Thushara.
Hi Yordan,
I've compared the Cache.cfg you have send me with the cache configuration file of mine. Both are identical only.
The ccs version I'm using is 5.5.0.00077.
The issue I'm facing is that if I have a cfg_script like the one shown below, the program is loaded properly and it hits the main function also.
var Cache = xdc.useModule('ti.sysbios.hal.unicache.Cache');
var Timer = xdc.useModule('ti.sysbios.timers.dmtimer.Timer');
Cache.configureCache = true;
Cache.enableCache = false;
Timer.checkFrequency = false;
But If I've my cache enabled as in cfg_script shown below.
var Cache = xdc.useModule('ti.sysbios.hal.unicache.Cache');
var Timer = xdc.useModule('ti.sysbios.timers.dmtimer.Timer');
Cache.configureCache = true;
Cache.enableCache = true;
Timer.checkFrequency = false;
The program loaded gets stuck in some function;it never hits the main,though it shows running state.
Further debugging revealed the following :
1) Its starts properly at c_init and goes to memory section corresponding to ti_sysbios_hal_ammu_AMMU_init__I.
2) Using "step into" key it came till address 0x80001844 (ref figure 1),
FIG:1
3)From the last position, address handles goes to location 0x80004f50 (ref fig 2).

4)If we try to step into further we will get a window like the one below (ref fig 3) and the thread goes into running state.

If we try to pause it will return the following error message in console:
