  • Forum Post: NDK Memory Footprint

    J. M.
    Hi, I have been using the NDK successfully on the C6474, however I am concerned about the memory footprint. I link the different subsections into L2RAM, however the size of the FAR:PACKETMEM section from os.lib is ~330k, whereas in the user's guide it states it only requires 32k-48k 1) Is there...

  • Forum Post: Too much overhead on back-to-back SPI data reads

    Paul Cohrs
    I am using pspdrivers_01_30_01 drivers to communicate over the SPI to 4 other devices. I am using four of the chip select outputs. I need to read 32 bytes of data from each device in a quick sequence. Running the SPI port at 10MHz, the actual data read is approximately 27 micro seconds. but the total...

    I'm running on an OMAP-L138. I'm trying to do QDMA transfers, following the LLD example code. I have almost everything working, but I've run into a puzzling problem. I have a callback set up to set a SEM when the transfer is complete. The call back is being called and calling HWI_isHWI...

  • Forum Post: How to reduce delay between SPI packets? OMAPL138 - SPI - ADC (ADS8361)

    Joseph CJ
    Hello, I am trying to make an OMAPL138 DSP core talk with a 500ksps ADC (ADS8361) via SPI1. Since ADS8361 doesnt have a specific SPI port, I am sending 0xC0,0x00 and 0x00 as SIMO to the RD line of ADS8361 and reading 24 bits from the Data A of ADS8361 as SOMI (see the code snippet below). I am using...

    Patrick Moore
    Hi Guys, I've a small problem here and hopefully you can point me to where I'm going wrong. First off the problem, we have a DSP/Bios program running on a DM3730 which receives configurations from the ARM side. The control interface runs within a TSK which runs at start up. During...

  • Forum Post: DSP/BIOS 5 vs SYS/BIOS 6 and DSPLink version suggestions?

    Judson Wilson
    I have played around with both versions a little bit, and have read various docs and wikis. SYS/BIOS 6 appears to be very feature rich, however when I look at the code size benchmarks it appears that the code size bloat has been on an exponential path for every subrevision. This worries me because...

    I'm developing an application for the DSP core of an OMAP-L138, using the uPP interface to an FPGA, and DSPLink message queues to the ARM core. The application runs correctly for a short time, then abruptly ends up in UTL_halt(). With my limited JTAG capability, I've managed to tease the following...

    Hi, I am using the OMAPL138 device. I’m using the DSP McASP interface with 3 AIC31 codecs on the same McASP. Each codec is connected to a different serializer. I started from the provided PSP 01_30_01 example. It works fine for one codec as in the example. But the problem is to...

    I want to use BCACHE API's on C674x devices. I use DSP/BIOS v5.x. I saw that it was written to the document(SPRU403R:2.2 BCACHE Module) that BCACHE API's of v5.x is available only for C64x+ devices. Is BCACHE API's available for C674x devices? If it is not available, in DSP/BIOS v5...

    Hello Relevant Person, We are using TMS320VC 5509A in our custom board and we created our project using DSP/BIOS 5.41.11.38 in CCSv5 . Our problem was that we could not achieve SDRAM to put in self-refresh mode. We have done lots of tests and analysis to find out the source of the problem. And then...

    Is it possible to create an RTSC/SYS/BIOS project for the C5535 device? When I create the project, if I set the device to TMS320C5535 the RTSC target is empty, and that later creates problems. If I choose TMS320C5505 instead, the target defaults to ti.targets.C55_large, which later indicates "Target...

    Hi, I got a question from my customer about MEM_alloc and MEM_free. In their code, it is possible that one MEM_alloc is called very close to MEM_free with same input parameters. So they would like to know if the return address of MEM_alloc will be same as the input address of MEM_free. What's...

    Todd, I am always specifying MSG_WAITALL. I found a work-around for this issue. Since I know I am getting a packet back from the computer when I send the request, I put in this code prior to calling the recv function: while (results == 0) { errorCode = fdStatus(CD11BaseSocket, FDSTATUS_RECV, &results...

    Todd, I re-tried the recvnc function and it worked. I thought the MSG_WAITALL waited until the entire packet was received, not the total buffer size. I guess I will use the recvnc with the SOCKETNC since it seems to work well. THanks, Will

This is because I have a 1 second epoch. Is a 1 second timeout the fastest connection timeout possible with the...
