Thanks for the help, I have corrected some errors and now I can send data and I can also read them. The only thing is that now, instead of reading what the pn532 should send, I read 0x80 all the time.... I don't know why. I think I'm sending the commands it needs...

Forum Post: TMS320F28379D: I cannot reprogram flash after first programming
Part Number: TMS320F28379D Other Parts Discussed in Thread: UNIFLASH Hi, I had a chip TMS320F28379D with blank flash. I succesfully programmed it with my program: int main(void) { EALLOW; Flash0EccRegs.ECC_ENABLE.bit.ENABLE = 0; EDIS; EALLOW; *(Uint32 *)0xD00 = 0x0B5A; EDIS; InitSysPll(XTAL_OSC,IMULT_40,FMULT_0,PLLCLK_BY_2); [...] As you see InitSysPll has been called with XTAL_OSC but this clock signal is not provided. I cannot erase nor program flash using CCS and UniFlash. I even cannot check if the chip is blank. Uniflash signals following errors: [2.11.2021, 08:05:21] [INFO] C28xx_CPU1: Executing Blank Check... [2.11.2021, 08:05:44] [ERROR] C28xx_CPU1: Error occurred during flash operation: Timed out waiting for target to halt while executing wr_pll.alg [2.11.2021, 08:05:44] [ERROR] C28xx_CPU1: Error writing the PLL values (Flash algorithm timed out). Operation cancelled. [2.11.2021, 08:05:44] [ERROR] C28xx_CPU1: Perform a debugger reset and execute the Boot-ROM code (click on the RESUME button in CCS debug window) before erasing/loading the Flash. If that does not help to perform a successful Flash erase/load, check the Reset cause (RESC) register, NMI shadow flag (NMISHDFLG) register and the Boot-ROM status register for further debug. [2.11.2021, 08:05:44] [ERROR] C28xx_CPU1: Flash Programmer: Error initializing device. How to recover the chip? Kind regards, Piotr Romaniuk PS I can connect via JTAG to the chip CCS without programming flash and then check registers, setup breakpoints and make step execution. In debuger I tried to change oscillator source (to INT2_OSC). I setup breakpoint before InitSysPll and then modified register that holds this argument. Unfortunatelly PLL was never locked and program stuck at: ClkCfgRegs.SYSPLLMULT.all = ((fmult << 8U) | imult); // // Wait for the SYSPLL lock counter // while(ClkCfgRegs.SYSPLLSTS.bit.LOCKS != 1) <<<<< stuck here { // // Uncomment to service the watchdog // // ServiceDog(); } } }

Forum Post: TMDSCNCD28388D: pto_abs2qep Example can not run from flash
Part Number: TMDSCNCD28388D Hi I'm testing pto_abs2qep Example via TMDSCNCD28388D This Example can run correctly from RAM.. But Not Flash.. and this has no 'Build Configuration for Flash' .. so I made it below is my work 1. add f2838x_codestartbranch.asm and change entry_point to code-start. 2. change cmd file to 2838x_flash_lnk_cpu1.cmd 3. add define "_FLASH" 4. remove "__attribute__((ramfunc))" for int16_t main(void) after that I can run Example from Flash via Debug window.. But when I try to Stand Alone booting.. the board is not working... the other (led example) is work properly.. and I found one thing.. when I comment out "pto_abs2qep_runPulseGen()" from pto_abs2qep_setupPeriph() and all of pto_EPWM3ISR() code then board can boot stand alone.. is there any suggestion..??? or can i get pto_abs2qep Example for FLASH booting?

Forum Post: RE: TMDSECATCNCD379D: SPI peripheral interface data transmit and receive error
Hi, Veena: I checked the polarity and phase configuration. There is no problem with these settings. I am able to send data from STM32F master device to my TI slave device. I changed the STE (CS) pin of the STM32F master device and the problem was solved. TI slave device is not sending data to STM32F master device. I don't see any output signal on SPI GPIO pins when TI device is in slave mode. I can get output signals from SPI GPIO pins when my TI is in master mode. Why won't my TI send data when in slave mode? Thanks, Sinan.

Hi Sinan, The slave device cannot initiate a data transfer. Once you write to the TX buffer, it will remain in the buffer till the master device initiates a transfer. You can make the master device send some dummy data to receive data from slave device. Regards, Veena

Forum Post: RE: TMDSECATCNCD379D: SPI peripheral interface data transmit and receive error
Hi Sinan, As per the SPI protocol, the data is shifted out on the SPI lines based on SPICLK and the SPICLK is generated by the master device only. Both devices send and receive data at the same time. In case master requires the slave to send a data but master doesn't wish to send any new data, it can initiate a dummy data transfer. Eg: Write 0 to master TX, so that the the SPICLK is generated and slave can shift out the data to be sent. Please refer to the SPI Operation chapter in TRM for more information Regards, Veena
