Forum Post: TMS320F28377D: Flash modified unexpectedly after power cycle
Part Number: TMS320F28377D Hi team, I noticed a rare issue in my customer's project. Currently they are using F28377D with a customized bootloader. In the bootloader, they have a CRC algorithm as below. Under normal conditions, the code was able to pass the CRC test successfully. And the code is widely used in all their products. So we believe the CRC algorithm it self is right. However, we noticed that if the MCU is powered down(together with power stage), there is a possibility that the code cannot pass the CRC test after the next power up. It seems that the Flash is modified during the power down. We believe that should be some unexpected spikes or interference which caused this problem. Could you please give some instructions on which may cause the Flash modification problem？ The hardware design around which pin should be checked carefully? { UINT16 uiCRC = 0, uiNonZeroDetect = 0, temp,i; UINT8 z; UINT16* p; UINT16 crc_table[256]; for(i=0;i > 1); z = z ^ (z >> 2); z = z ^ (z >> 4); *(crc_table + i) = z & 1 ? 0xC001 : 0; *(crc_table + i) ^= i > 8) ^ *(crc_table + ((uiCRC ^ (temp >> 8))& 0x00ff)); uiCRC = (uiCRC >> 8) ^ *(crc_table + ((uiCRC ^ temp )& 0x00ff)); } if ((uiCRC == 0) && uiNonZeroDetect) { return(1); } return(0); } Regards, Brian

Hello Alexander, I can't run your code until tomorrow afternoon, but in the meantime can you at least explain what you are doing to send data to the bulk device? Is your host the PC using the TI application I mentioned above? Or is the host another source?

Forum Post: EK-TM4C1294XL: AWS Cloud Connectivity With GSM Modem
Part Number: EK-TM4C1294XL Hi, We are in the development stage of an attendance and tracking system. The hardware platform we are using is Tiva TM4C1294XL launch pad We are using Amazon Free RTOS as OS and application is to get RFID data from a RFID reader and to upload the data to the cloud. We are using a GSM modem (SIM808 module based ) to upload data to the cloud. The GSM modem communicates with Tiva board only through UART interface. Using AT commands for configuration and GPRS upload. We have got a reference of CC3220 launchpad connectivity with AWS endpoint using WiFi, certificate and policy.(The reference demo is part of Amazon Free RTOS ) Instead we need to use the UART interfaced GSM modem for AWS connectivity and publish/subscribe. It is very much helpful getting any reference implementation or some guidelines to get access to AWS with Tiava TM4C1294XL and GSM modem Thanks in advance Best Rajesh Kumar V

Forum Post: CCS/TMDSHVMTRINSPIN: TMDSCNCD28069MISO, proj_lab1b debugging error with connected motor
Part Number: TMDSHVMTRINSPIN Tool/software: Code Composer Studio Encounterd an error at step 3. Step 3. Connect motor, power on EVM kit, Enable the real-time debugger again. Set the variable “gMotorVars.Flag_enableSys” and “gMotorVars.Flag_Run_Identify” equal to 1 again. Set the variable “gMotorVars.SpeedRef_krpm” to a different value to ensure the motor still runs. The moment I change "gMotorVars.Flag_Run_Identify" to 1 with HV power on. Driver loses connection with the board. The picture above shows and the motor starts to rotate. At TMDSCNCD28069MISO two blue LEDs continue to be ON permanently. Then I tried to use DC low voltage source (0V - 60V). I started with 20V, changed "gMotorVars.Flag_Run_Identify" to 1... everything fine. Slowly rised voltage to ~30-35V, same error showed up. (motor not rotating) I am using CC version: 9.0.0.00018 clean install. Any suggestions?

Forum Post: TMS320F280049: Why DCSM does not have CLA bit in Z1_GRABRAMR register?
Part Number: TMS320F280049 Hi team, I noticed a obvious difference between the DCSM of F28004x and F2837x? In F2837x we have a GRAB_CLA1 bit in Z1_GRABRAMR register to allocate the CLA to a zone, so that the CLA will be able to access to the memory within the same zone. However, in F28004x we do not have this bit. In this case, how to authorize a CLA to access a bank? Regards, Brian

Forum Post: TMS320F28377D: using AES encryption in C2000 series
Part Number: TMS320F28377D Hello TI engineers Recently, our company want to use AES encryption in TI's C2000 series, and I have found the AES encryption source in the TI's website( www.ti.com/.../aes-128) the encryption function we used is as below, void aes_enc_dec(unsigned char *state, unsigned char *key, unsigned char dir) but I met some trouble when I use it, As you know, the minimum data unit of TMS320F28377D is two byte, that is to say, "char" type in TMS320F28377D is two byte. It is a little special with others. so I think this function could not be used in TMS320F28377D . is there a encryption source that could be used in TMS320F28377D ? or how could I do some modification to it so that it could compliant with TMS320F28377D ?
