Hi guys, i've some doubts about possibilities to use DMA to reaload the reload timer 0 register (PRD) ,is that allowed on C5402? How could i implement a sort of PWM with timer output pin (i.e. TOUT0 driving a toggle flip-flop) w/o using an isr for each commutation? Gl.

Hi, I have designed a board using TMS320VC5402 DSP. I am using HPI bootloader. I am also using parallel port bootloader to load code from 8 bit parallel EEPROM. Initially both the bootloaders were working fine. I could load the code to internal DARAM and execute it.

Hi all, I wonder if it is possible to flash a Flash ROM though the Jtag Dsp. I 'm using a C5402 dsp , a parallel FLASH type M29W200 or AM29VL200 and CCS1.2 Any help would be appreciated, regards, julien Boudias.

I have some troubles bootloading from serial port. My problem is quite complex : I have a C5402 DSP linked to an ARM7 core based chip through McBSP0 (SPI). I have to bootload code onto the DSP using the ARM because my DSP have no access to flash memory. The ARM is configured as a mas

Dear all Maybe someone can shed some light for me. I am designing a prototype with a C5402 DSP and JTAG interface. I have the DSK specific versions of Code Composer Studio. I further have a XDS510PP and a XDS510PP Plus emulator form Spectrum Digital and Code Composer 4.10 (rec

Good day. Happy Thanksgiving to those cebrating this occassion! From the CPLD control register 2, the FLASHENB bit will determine whether the external memory is FLASH or SRAM. Does that mean that FLASH & SRAM cannot be enable at the same time? FLASH has a 7 wait-state latency &a

Thanks to those who emailed me with your suggestions, it fixed the "data verification at FF80" problem. You need to peform a GEL routine 5402_DSK_Init before you load the coff file. Then perform a Reset DSP, and everything works fine. Note, however, sometimes the cof

Hello all, I have designed C5402 to support extended address that falls in 0x10000-0x18000 range. Before my HW becomes ready, I have to rely on CCS1.2 simultor to develop software. By default C:\ti\drivers\sim5402_ext.cfg only allows 0x18000-0x1ffff. I have modified it t

I have a C5402 DSK, and I'm trying to do a serial communication using the DB9 connector to a microcontroller(AT89C52). The microcontroller can communicate serially with my computer perfectly, and so does the TMS320VC5402 also can communicate serially with my computer perfectly.

Dear group I am doing a design with a C5402 DSP and flash memory module. Can someone give me some pointers to the logic control interface to the flash memory. The processor needs to boot from flash memory. SPRA585 recommends the use of the XF pin on the DSP, but as the DSP sta

I have been receiving requests for ad50init.asm file, which initializes the AD50 codec on the C5402 DSK board using asm language, intended for very small footprint applications that do not use DSP/BIOS. The file was posted on the C54x group archive for almost 2 years bu

In microprocesser mode, the 5402 places its interrupt vector table in external memory. Since external memory is very slow, I am considering relocting the interrupt vectors to internal DARAM. The documantation mentioned that this can be done by setting the IPTR bits in the PMST regist
