Hello everybody I am using the on-chip flash programmer in CCS 3.3 to program a F2812. After clicking execute program in the on-chip flash programmer window, first it started working normally but at the beginning of the erasing procedure it stopped. I waited for a long but there was no progress in that procedure. I decided to close the on-chip flash programmer window, reset the board and unplug ...

Hi, I am using F2812 chip to implement the following. 1- Generate a symmetric three phase PWM, PWM7-12, using EVB on chip. 2- Map the compare match 4, CMP4, to call a software Interrupt service routine using PIE. The first task, PWM generation, was successfully done. I have verified the physical hardware output using a scope. However, for the second part, compare match Interrupt, I couldn?t

Hi all, I have bought a few DSP - TMS320F2810 from a broker. When opening the flash utility, the flash is password locked. When the password addresses in flash memory((0x3F7FF8 - 0x3F7FFF)) verified, it shows all zeros. This means that, the DSPs are already locked. But without knowing the password, it can never be unlocked, using JTAG emulator. Does , anybody know , some other metho...

Hi, I'm a college student from argentina and I've received a Texas Instruments DSP Control Card with a 320F2808 and another with 320F28335, and I'm kind of lost. I've downloaded the CCSv4 and tryed to begin programing, but I found I´m missing the basic concepts. If any one can help me with this, I will be very thanked. My basic questions are: 1) How do I adress the registers in the core? I've...
