Darryl, The error seems to indicate what Marlyn mentioned: a faulty install. However, since you showed the files present on the CCS install directory, I have another suspicion. If you are using the built-in debug probe of the The LAUNCHXL-F280049C, its model is the XDS110 Debug Probe, not the XDS100v2. This is a common occurrence if you created/imported a project from the C2000Ware, since all the current projects seem misconfigured and point to the XDS100v2. Please check the short clip below to learn how to proceed to change this: https://youtu.be/4ZoXwM3-Szw Hope this helps, Rafael

Forum Post: RE: CCS/RM46L850: RM4
Hello Rakesh, The EMAC internal logic is clocked synchronously on the VCLKA4. The MDIO clock is based on a divide-down of the VCL3. VCLK3 is the peripheral clock divided down from HCLK which is from PLL1 or PLL2 VCLKA4 can be from VCLK or from PLL1 or PLL2. You can use only PLL1 for this example. PLL2 is the 2nd option for tis example.

Forum Post: RE: MSP430G2553: MSP430G2553 & TLIN1029DRQ1
Hi Ling, Thanks a lot for your feedback. The application code hasn't been developed yet since I'm just starting to develop the hardware, but I believe LIN transceiver generally require at least 128KB hence the need to confirm the MCU memory bandwidth. I appreciate that MSP430 family support up to 256KB program memory. But when I look at the datasheet for MSP430G2553 and MSP430F2272 (which were previously recommended by TI's FAE), I only see 16KB and 32KB, respectively. Question I have is that does MSP430G2553 have program memory required for a LIN transceiver or should I look at other MCU's within MSP430 family? If so, which ones do you recommend? Thanks, John

Forum Post: CCS/TM4C123GH6PM: TI RTOS Runtime Object Viewer CCSv9
Part Number: TM4C123GH6PM Tool/software: Code Composer Studio I have recently upgraded from CCSv8 to CCSv9. This has caused some issues when trying to launch ROV (Runtime Object Viewer) during a debug session: I have followed the system paths and all necessary components are installed where expected. Is there another path setting that needs to be changed? Perhaps as a result of moving from CCSv8 to CCSv9? Many Thanks, Tom

Forum Post: CCS/LAUNCHXL-F28377S: ADC read in EPWM interrupt
Part Number: LAUNCHXL-F28377S Tool/software: Code Composer Studio Hi everyone, I have a LAUNCHXL-F28377S. In my project, I need 100kHz PWM signal and four (4) channels ADC port. I use EPWM intrrupt with 100 kHz. And I want to read the ADC channels in each EPWM interrup. So, I use the A0 - A1 - B0 - B1 ADC channels with SOC0 and SOC1. Each SOCs are triggered by EPWM interrupt. But, I have problems reading ADCs. If one channel conneted, ADC read the correct value. But,, if two or more channel connected, ADC have read wrong value. Where is the mistake? Thank you.

Forum Post: TMS320F28388D: NMI and Missing Clock Detect and Boot ROM
Part Number: TMS320F28388D Hi, I'm reading the TRM about the Missing Clock Detection logic and the associated NMI mechanism. Could you help me with these few questions? In the example sysctl_ex1_missing_clock_detection in driverlib it is explained that INTOSC1 can be used after a MCD as OSCCLK to restart the PLL and generate SYSCLK at 200MHz. Does it mean INTOSC1 can be used for 200MHz and it is only INTOSC2 that is limited to 194MHz (see datasheet)? In order to know if a Missing Clock Detect has occurred is it better to check the MCDR[MCDSTS] flag or the NMIFLG[CLOCKFAIL] flag? As far as I can understand the boot ROM clears the NMIFLG[CLOCKFAIL] flag and updates the "CPU1 Boot ROM Status" so does it mean that it's pointless to read NMIFLG in my application? The CLOCKFAIL signal is shown entering the Trip Zone submodule of the ePWM peripherals on the TZ5 input. Can someone confirm that it can then be configured like any other trip source during ePWM initialization, so that we can decide whether the PWM outputs should be driven high or low upon a CLOCKFAIL event? Kind Regards, Pierre

Part Number: MSP432P401R Hi, I have an MSP-EXP432P401R, rev. 2.0, board in front of me (two of them, in fact) with the MSP432P401R MCU. After downloading everything I could find instructions about, I typed the device name into the "Select a Device or Board" field on the top left of Resource Explorer and found "MSP432P401R LaunchPad Rev. 2.x (Red)". (There is no "MSP-EXP432..." so I figure I've got the right thing.) I expanded the tree for 'Software' and then 'SimpleLink MSP432P4 SDK - v:3.20.00.06', then 'Examples', then 'Demos', then 'outofbox_msp432p401r', and then double-clicked on the "Out of Box Experience GUI" item. The text says: MSP-EXP432P401R Out Of Box Demo Target Status: Disconnected. When I click "Connect", it just sits there saying "Connecting..." seemingly forever. There is power to the board. This is supposed to be the out-of-the-box easy blink demo. What could I be missing? (I read two similar-sounding posts, but I'm not at the point of using a probe or anything. I'm just taking the thing out of the box, literally, and trying to see the demo.) Thanks

Forum Post: CCS/MSP432P4111: MSP432 BSL Software Invocation Documentation Is Lacking
Part Number: MSP432P4111 Tool/software: Code Composer Studio Hello, I have seen some other posts in the forum where users have trouble with the software invocation of the MSP432 BSL. The symptom is that the BSL works fine when invoked via hardware invocation or the lack of a main program (0xFF in first 8bytes of main memory). I ran into the very same problem as mentioned here(), but the solution there was not complete. I have found that the software invocation should look like the following: Interrupt_disableMaster(); for (int i=0; i IP[i] = 0; // This is critical! However SLAU622H does not mention this for SW invocation. NVIC->ICER[0] = 0xFFFF; NVIC->ICER[1] = 0xFFFF; NVIC->ICPR[0] = 0xFFFF; NVIC->ICPR[1] = 0xFFFF; BSL_INVOKE(BSL_UART_INTERFACE); My key finding was that the interrupt priorities MUST be reset to zero. I also reset the Systick (BSL uses to find the baud), Timer A0 (BSL uses for 10 second timeout), and USCI A0 (UART used to program). So I add the following code prior to entering the BSL: /* Make sure our MPU settings don't cause problems in the BSL. */ MPU_disableModule(); /* The BSL does not initialize some hardware it uses. It requires * the Systick (to determine UART baud rate) and Timer A0 (to set * the 10-second timeout). Prepare these for use by BSL. */ SysTick_disableInterrupt(); SysTick_disableModule(); Timer_A_stopTimer(TIMER_A0_BASE); /* Need to reset UART A0 for firmware update. Be sure to make the * corresponding GPIOs input pins. */ UART_disableModule(EUSCI_A0_BASE); GPIO_setAsInputPin(GPIO_PORT_P1, GPIO_PIN2); GPIO_setAsInputPin(GPIO_PORT_P1, GPIO_PIN3); I hope this helps someone. You may want to update SLAU622H with the interrupt lines above. I was going nuts trying to figure out how to invoke the BSL for firmware updates in the field! Best, Mike

Forum Post: TMS570LC4357: Is it possible to write to peripheral registers with the HTU?
Part Number: TMS570LC4357 Hello, I'm trying to configure a peripheral register using the the N2HET by passing data using the HTU. I have the N2HET and HTU working well(I'm able to read/write from the RAM (512kB) portion of memory). However, I can't seem to write to peripheral registers. I'm specifically talking about this region here: Is it possible to write to the peripheral registers using the HTU? Am I missing something? Thanks.

Forum Post: MSP430FR5989: UBDIFG and UBDRSTEN; GC5 Errata
Part Number: MSP430FR5989 Hi, if I have GCCTL0.UBDIE = 0, GCCTL0.UBDRSTEN=0 and GCCTL0.CBDIE = 0, is it possible to have UBDIFG bit set by HW while the error reporting is turned OFF and later on when SW enables the Error reporting, for ex: sets GCCCTL0.UBDRSTEN = 1, then I get a PUC immediately. If so, it is safer to clear the UBDIFG before I turn ON the error reporting (PUC or NMI) right? This in relation to the GC5 Errata, does it make sense to include clear the UBDIFG flag (any other FRAM error detection flags) before re-initializing the GCCTL0 to enable PUC generation? W.r.t GC5 errata work around how is it guaranteed that the first access to FRAM after wake up doesn't set the UBDIFG? Best Regards Santosh Athuru
