Part Number: TMS320F28379D I am working with the PM_bissc_SystemTest example for bissc, and I met a strange problem. When I run the program, it cannot enter the SPI interrupt function(interrupt void bissc_spiRxFifoIsr()), and always wait at ( while(biss_data_struct.dataReady != 1)), but when I pause the program and continue to run the program, It can enter the SPI interrupt function, and the rest of code runs correctly. Now I need pause-run-pause-run....... I don not know why... Now I have two pieces of board to run the example, and another is normal !!

Forum post: TMS320F280049: will the noise of 3.3V supply affect the connection with the debugger?
Part Number: TMS320F280049 Customer found F280049 always failed to connect the debugger through JTAG. I found they are using TPS561201 to provide the 3.3V for F280049, and it would enter PFM mode(Pulse Skip Control) during light load, which might bring with more voltage ripples/noise. I am not sure whether it will affect the stability of the connection with the debugger. If so, I will suggest them to use TPS561208 with CCM during light load. Could you please help check my assumption? Thank you.

Forum post: TMS320F280049C: FSI test issue
Part Number: TMS320F280049C Hi expert: My customer wants to use FSI to communicate between two C2000 Board. I suggest them begin with: http://www.ti.com/lit/an/spracm3/spracm3.pdf Firstly, they use two launchpads, download the code into Flash, but nothing happened, both GPIO16 are low. And there is no signal in CLK and data0. Then, they try 1 control card and 1 Launchpad. I add _LAUNCHXL_F280049C to pre-define symbol to change the GPIO. Connect both boards with CCS, emulation mode. RAM code. This time, both GPIO16 are high. However, The lead code is stuck at ESTOP0(fsi_ex16_daisy_handshake_lead.c); since this is Error. while(1) { #if FSI_DMA_ENABLE==0 // Now, start transmitting data frames // Fill TX array with new data prepareTxBufData(); // Write data into Tx buffer // Start the first transfer FSI_writeTxBuffer(FSITXA_BASE, txBufData, nWords, 0U); FSI_startTxTransmit(FSITXA_BASE); // // Wait for TX frame done event // while(fsiTxInt1Received != 1U); // Set FSI TX circular buffer pointer back to beginning FSI_setTxBufferPtr(FSITXA_BASE, 0U); // // Wait for RX data frame received event // while(fsiRxInt1Received != 1U); // Set FSI RX circular buffer pointer back to beginning FSI_setRxBufferPtr(FSIRXA_BASE, 0U); if(error == 0) { fsiTxInt1Received = 0U; fsiRxInt1Received = 0U; } else { // Error occurred during communications ESTOP0; } I also change lower CLK, but nothing changed. #define PRESCALER_VAL FSI_PRESCALE_10MHZ #define PRESCALER_VAL FSI_PRESCALE_5MHZ Except that, I did not change the code. Could you kindly tell me where I did wrong? BR Emma

Forum post: CCS/LAUNCHXL-F28379D: ADC does not appear to sample as often as expected
Part Number: LAUNCHXL-F28379D Tool/software: Code Composer Studio Hello, I am using the LAUNCHXL-F28379D microcontroller EVM along with an AD9833 waveform generator. I am currently at the stage where I am just trying to make sure that my ADC can effectively sample the sine waves that I am generating with the AD9833 but have run into some trouble. I am essentially just using the adc_soc_continuous_cpu01 example from ControlSuite combined with some of the SPI commands from the spi_loopback_cpu01 example. I know that my SPI communication with the waveform generator is operating properly because when I command a 5kHz signal, I can see the following on an Oscilloscope: (note that the Oscilloscope probe is set to 1:10 amplification and the actual peak-peak value is only .66V) Essentially when I try to return the same plot using the ADC, the waveform I get is a mess. I believe I have all my settings correct to guarantee the highest sampling rate I can (SYSCLK = 200MHz, ADCCLK = 50MHz) but from what I can tell, it appears that the ADC is sampling much less frequently than that, since it only takes about 20 samples to capture a full period of the 5kHz waveform. Below is the code I am using, apologies if it is a bit messy: //########################################################################### // FILE: Example_28X7xSpi_FFDLB.c // TITLE: SPI Digital Loop Back program. // //! \addtogroup cpu01_example_list //!

Forum post: CCS/TMS320F280049: power cycle issue not restarting program on custom PCB
Part Number: TMS320F280049 Tool/software: Code Composer Studio I'm having issues with a program I wrote for the TMS320F280049 on my custom PCB not restarting after a power cycle. The hardware is derived from the F280049M controlCARD development board. Whenever I program my PCB using the XDS220 ISO JTAG programmer, the PCB functions as expected. I'm able to debug the software, view registers, watch variables, etc. As soon as I power cycle the PCB, the program no longer restarts. When I upload the same software using the same tools onto the F280049M controlCARD development board and perform a power cycle, the development board restarts. I have checked my supply ramp rate on my custom PCB and it's circa 1000 V/s which is within the datasheet specifications. I'm baffled as to why this only occurs to my PCB and not the development board. Am I missing something completely obvious with the CCS9 settings or have I missed something in my hardware?
