  • Forum Post: Why is it so difficult to assign bios memory sections for SYSBios verses DSPBios?

    William Macre73633
    This is the Platform window for setting the various fixed (internal) and user defined (external) memory sections using CCS4.2.2. Note that under “Memory Sections” you must select only one section for each of code, data, and stack memory. But as shown in the load maps created with CCS 3.3...

  • Forum Post: RE: Getting MEM_alloc segid

    will Resnick
    Steve, What I want to do is only have to define the size of the buffer once in my .tcf using a variable created in the .tcf and then use that variable to initialize some arrays in my .h files. I also need to reference the variable in my .c files. Is that possible? I am not sure how the print statement...

    Steve, Sorry that I seem so scattered. In returning to the MEM_alloc question, even when I add the extern to my .c file, the compiler still can't find the variable DDR_HEAP. Thanks, Will

    A BONNET
    hat is the difference beetween these 2 kinds of gates. In the documentation, I understand that in the 2 cases, interrupts are disables when entering the gate to lock resource. I would like to have the most general critical section to share resource beetween tasks or beetween task and hardware interrupts...

    Adri��n Gonz��lez
    Hello, everyone. I've been developing a FIR filter for a while in the TMS320C6670 DSP and I need to increase the processing frequency as much as possible. In order to do so, I use DSPLIB to filter (it has good benchmarks) and SYS/BIOS. My idea is to split the input data buffer into 4 segments and...

    barry mohan
    Hi All We are using CCS4.2, Bios 5_41_10_36 on OMAPL138 with emulator (XDS560v2). Usual problem is if we add too many LOG_printf's to the system it affects real time behaviour too drastically - we decided to use multiple LOG buffers/pre-defines to overcome this as follows: #ifdef USE_LOG1 ...

    Including that file path fixed my issue. It also appears that I don't need to include Semaphore.h. Why is that? Thanks, Will

    Hi, I am trying to create a shared timer for the c6678. I know that sys/bios uses main timer 0 from reading other posts.

    Hi Steve You are correct it is related to the original post - but we don't control the PSP package (ie don't know if it uses TConf and dispatcher) we simply call the BIOS function GIO_Submit() and supply if with the required parameters #include <ti/sdo/edma3/drv/edma3_drv.h> #include...

    Hi Again Steve Perhaps the correct question is : Is there a method to check if the GIO_submit() callback function declared as "GIO_AppCallback spi_dma_callback1;" has been pre-configured using the Tconf file. BR Barry
