    Hi Guys, I have a customer who is permanently damaging (blowing) the F2811 DSP when attempting to program the FLASH the JTAG. So far he has damaged 6 parts on different PCBs. He tried using a different emulator and also a different PC but the problem still occurs. If he manages to succesfully progam...

    Magnus Wohlfart
    Champs, A customer is using a TMS320F2812 DSP and wants to migrate to the 28335. The problem is now that on the 2812, in the EVx capture, we had a capture fifo status register CAPxFIFO that reflected the number of entries in the capture fifo. On the 28335, there is only the so-called "Mod4-counter"...

    Wei Jiang16209
    Hi, one section of my codes (SCI peripheral) works fine when I ran the EzDSP F2812 in RAM (other parts such as PWM works fine), however, yields no output when i ran the program in flash, I need to watch the variable when the program runs in flash, is there any way to do that? thank you

    I am little rusty on this but I know this can be done - you program your flash, then connect JTAG, open CCS and project, don't build or load the file. Now load only symbols and you are ready to go. Follow steps to run the code in real-time and add the variables you want to watch in watch window....

    Hello Everyone, My question is very simple. What's the effective (max) range/distance for SPI communication between 2 2812 processors? The processore clock speed is 120 MHz, and the SPI bus is running at 7.5MHz. I know this can be a loaded question, as there's no standard spec or SPI communication...

    Well, in this example STM is enabled so from what I read in the documentation I shouldn't need a receiving node to send an ACK. I have hooked upan oscilloscope to the CANTX pin on my dsp board and it doesn't pick up any signals. All the code I'm using is provided sample-code from TI (including...
