basic setup circuit - bandung_laiciais - Mar 20 8:50:27 2008
Hello All, I am research student and doing project with dspTMS320VC33 chip (not DSK)to build some simple circuit for beginning. My simple circuit include dsp chip, oscillator, led for testing output at pin XF0 n XF1 and external memory (ATMEL EEPROM). I use bootloading mode for my project n already burn my program to the memory. The problem is that when i power up my circuit and give low and then high to pin reset, there's nothing happen. There's another pin that I must touch or something else. Anyone can help me PLEASE ------------------------------------ Check Out Industry's First Single-Chip, Multi-Format, Real-Time HD Video Transcoding Solution for Commercial & Consumer End Equipment: www.ti.com/dm6467 You can post a message or access and search the archives of this group on DSPRelated.com: http://www.dsprelated.com/groups/c3x/1.php _____________________________________

Mr. Laiciais, Where is your EEPROM memory mapped to? Do you have the appropriate INT pin pulled low, and the others pulled high? On your oscilloscope, do you see any activity on the address lines when you reset? What is the first word in your EEPROM? Do you have a JTAG emulator and Code Composer? I'm impressed if you're trying to go straight to EEPROM without debugging.

Thank for help My EEPROM memory mapped to boot 2 address 400000. I set INT0,INT2 and INT3 to 1 and int1to 0. I do not check at address line but check at output pin when reset and after reset and have activity on oscilloscope but to much noise and I do not know this is the right output or not My first word is 0x80000 Nop, I dont have Bill Finger <w...@creare.com> wrote: Mr. Laiciais, Where is your EEPROM memory mapped to?
