Hi All, I have assigned page0 as the chip enable for an external flash. But the page0 is not becoming active low on accessing an address range in between 0x00081000 to 0x003fffff. For that matter only my page2 is becoming active low in the address range 0x0080A000 to 0x00BFFFFF.page1 and page3 are also not becoming active low in their respective address ranges. I am using only the A0-A19...

Hello... I am having an issue with a TMS320C33 and I would appreciate some guidance. I am using the TI utility c3xcheck.asm and it is integrated into my boot-loader code. I am seeing failures at -30C to -40C and the self check utility returns a failure code for "ALU Test Integer Error". Is there any way this can be related to anything external to the DSP? I am having a hard time believing ...

We have a situation on one of our legacy design of 320C31 DSP. Reset pin of C31 is connecting to Maxim Power on Reset chip (MAX708). At power up, There is a clock coming in to X2_CLK of C31, but there is no divided by two H1 nor H3 clocks coming out. If we force external Master Reset to MAX708, to create C31 reset after power up, H1 clock will come out. Once the H1 clocks coming out, we ...

I have a system running that uses the Serial Port interrupt. It is the only interrupt enabled in the system. All processes are launched from the interrupt service routine. There are 4 interrupts spaced about 2.5 usec apart, followed by 10 usec period of no interrupt. Thus we have about 200,000 interrupts/sec. The ISR itself, with overhead for call and exit, has a worst case execution time of ...
