Hi Vivek , I have changed the user otp manually in Uniflash gui and then called the called the above commands in a batch file. So the memory doesn't have the previous security settings anymore. I found another thread where the same problem was occurring : Do you think it the uniflash code is not right ? Let me know how I should proceed. Regards Anish

Forum Post: RM48L952: Missing document: "TPS design document "
Part Number: RM48L952 Hi, I contacted costumer support, but they forwarded me to ask my question on the e2e forum. We purchased the SAFETI-HERCULES-DIAG-LIB-CSP . In the SafeTI Hercules Diagnostic Library Architecture Document (DOCUMENT ID: TI-SW-00199-SAD-01) section 3.1.3.6 on page 15 states : "TPS driver architecture is covered in the TPS design document". However, no reference to such document is available in the references section on page 21. I also can not find such document in the CSP nor in the documentation which is openly available. Where can I find this document? Best regards, Karel

Forum Post: RE: EK-TM4C123GXL: UART receives part of the message, with or without FIFO
Hi, Thank you for your response. I didn't think that the picture may mislead here. In the oscilloscope, the names are default ones, they have nothing to do with CLK or DATA. The blue line is the transmission from TIVa to the sensor, yellow one is the response. It is supposed to receive 45 bytes and stops after 6 bytes read and continues to poppulate the array with exact same values, that is my question why it does that. I have managed to fix that issue as it was the delay I kept from the example which I removed from the interrupt handler and it fixed that issue - it reads whole message. However it still adds a zero to first position of the array and only after that the response from the message. That is the only issue left to resolve. I do know that with other MCUs I have usued I didn't have this 0x00 byte added when interrupt is triggered and it is not part of the message, it just seems that the Tiva adds it by itself.

Forum Post: CCS/TMS320F28335: tms320f28335
Part Number: TMS320F28335 Tool/software: Code Composer Studio Hi my question is about “how to load application to FLASH RAM without emulator by SCI Boot loader.” The documents I have referred are “Serial Flash Programming of C2000™ Microcontrollers “and “TMS320x2833x, 2823x Boot ROM Reference Guide “. I’ve already checked hardware system I set for SCI communication with SCI echoback example code by TI. SCI communication goes well with my F28335 so it doesn’t seems to be have any issues on the hardware setting. My F28335 communicates with PC host through RS232 protocol. The photo below is the issue I have faced and i am unable to solve it out. I am guessing I put the wrong argument onto command argument inbox that can be found at “debugging tag” of Serial flash programmer property. The line below is the argument i gave. -d f2833x -k C:\ti\c2000\ C2000Ware _1_00_06_00\device_support\f2833x\examples \f28335_flash_kernel\Debug\f28335_flash_kernel.txt –a E:\CCS_Project\practice_v3.0\Debug\practice_v3.0.txt -p COM4 -b 9600 The reason I did those things above is because I referred the line 6 and 7 of “6.2.2 Building serial_flash_programmer in Visual Studio” in the document “Serial Flash Programming of C2000™ Microcontrollers". As the document I have mentioned above explains how to convert the .out file to .hex file at “6.1.1 Kernels” in the document mentioned above, i followed it with uncertainty. I enabled the hex2000 utility for f28335 flash kernel example in CCS and set my project property as below with a hope that I did well to produce the hex file required for SCI boot loader. It is said the format must be in the ASCII SCI boot format, which is why I check the square boxes as the photos above. I gave the same options to my project targeted to be load in FLASH RAM. After the setting above from ehx2000 utility, I could see hex file. I changed the .hex extension to .txt because of the description of “6.1.1 kernels” section. “f28335_flash_kernel.txt and “practice_v3.0.txt” are the extension modified files I got after build process. I have checked the boot mode select pins (GPIO 87, 86, 85, and 84). I set them for the boot by SCI loader so there seems to be no any problem. Thanks for your patience and your sincere answer on my question I appreciate!

Forum Post: CCS/MSP430FR5869: Can not successfully make a crc-16
Part Number: MSP430FR5869 Tool/software: Code Composer Studio I've been reading through the documentation in the user guide for the MSP430FR58xx family regarding the CRC-16 module. I use two variables in the test code. One with a seed, and one with the test data, that I want the CRC of. I have also defined the "baseAddress", which is used with the crc-related functions. The code looks something like this (it's in C++) Testcode: " uint16_t baseAddress = 0x0150; uint16_t seed = 0; uint16_t data = 123; CRC_setSeed(baseAddress, seed); //Initializing CRC module CRC_set16BitData(baseAddress, data); //Sending input data CRC_set16BitData(baseAddress, seed); //sending 16 0's to shift out the databits uint16_t result = CRC_getResult(baseAddress); //Storing the result in variable " I used uint16_t sizes as that is what the functions take as arguments. The above code gives the following result (in hex): 0A59 When I use the "bitsReversed" functions the result is (in hex): 563A It seems to work in a very simple manner with the functions, but at this point, I recognize that I must be doing something wrong. I'm looking for anyone who can tell me what's wrong. Thanks in advance. I checked my values with a bunch of online CRC-16 calculators, but nothing matches my output.

Part Number: MSP430F5529 Hi guys, I've been struggling to erase my factory programmed USB bootloader of my MSP430F5529 target and to change it with an UART BSL. So far I have no luck ...

I tried to download TI's UART bootloader from here: http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSPBSL_CustomBSL430/latest/index_FDS.html and flash with mspdebug the HEX file: MSP430BSL_1_01_00_00/Released_BSL_Images/MSP430F552x_550x_Family/UART BSL/BSL.00.07.05.04.txt but I get an error: Writing 1900 bytes at 1000... tilib: MSP430_Memory: Could not perform access, BSL memory segments are protected (error = 62) I'm on Ubuntu 18.04, 64-bit. I can flash a simple blinky with mspdebug or with Code Composer Studio, but I cannot unlock the BSL segment to rewrite the bootloader.

Forum Post: CCS/TM4C123GH6PM: SD Card overwrites previous data written
Part Number: TM4C123GH6PM Tool/software: Code Composer Studio Hi all, I am currently trying to make a stable communication between my Tiva TM4C123GH6PM and a SD Card. I need it because I want to save data from a variety of sensors in a single line in a text file continuously. I am able to create and write some data in the text file, but only once, because everytime the program remounts it, it seems like the position of the cursor of the text file resets, and the data gets overwritten. Is there a way to save the position of the cursor even when the file is closed and dismounted? Or is there a way to write in the text file without needing to close and dismount it? I am putting my program here for better analysis of the situation. Currently using the mmc-dk-tm4c123g.c examples to help. Regards, Álvaro. (Please visit the site to view this file)

Forum Post: TMS320F28379D: DMA not clearing ADC interrupt
Part Number: TMS320F28379D I am using a configuration where the EPWM2A is triggering ADCD conversions. ADCDINT! is enabled and each ADCDINT1 should trigger a DMA burst of 1 x 16bit read from AdcdResultRegs.ADCRESULT0. A DMA transfer consists of 100 such reads from the same register and then the DMA should interrupt the CPU at the end of the transfer. My observation is that the first DMA trigger is happening and the first ADC result is read. However, the ADCINT1FLG is not being cleared at this point and this stops any further interrupts being generated by the ADC. My understanding is that "Upon receipt of a peripheral interrupt event signal, the DMA will automatically send a clear signal to the interrupt source so that subsequent interrupt events will occur." So, I thought all I had to do was DmaClaSrcSelRegs.DMACHSRCSEL1.bit.CH1 = DMA_ADCDINT1; and the DMA would take care of clearing the interrupt on the ADC. I have confirmed this "stuck int flag" is the cause of the issue by hacking the software to clear the ADC flag while waiting for the buffer to fill : while(RxBufReady == RX_NOT_READY) { AdcdRegs.ADCINTFLGCLR.bit.ADCINT1 = 1; // Clear ADC INT1 flag } By clearing this flag in SW (which is obviously undesirable in the real system) I get the DMA transfer to complete and the DMA ISR is called. Without the line to clear the flag, the DMA transfer never completes. Another way I confirmed the stuck flag issue was to set the ADCINTFLGCLR in CCS. Every time I cleared the flag manually one more DMA read took place and then I was back in the same position with the flag set and no further ADC interrupts. So, am I missing something here ?? I thought by triggering the DMA on ADCDINT1 is would automatically clear the INTFLG for me?? Regards Lorraine

The modified falling edge is depicted by the red (color) line below. It is meant to occur before the rising edge of the RED signal. Would the ePWMA output have a similar waveform as the input, just delayed by RED and FED accordingly? Or would the ePWMA output be suppressed?
