Hi All, We are developing our own board with a TS-201 and trying to get it to boot via link port, and we're having a bit of difficulty getting it to work with the boot loader supplied by Analog. In trying to isolate the error sources, I went back to our EZ-KIT board and tried to get our code booted on that using the example program supplied by Analog - again, no luck. On the EZ-KIT I was able t...

Hello, I was wondering if it's possible to interface the EZ-kit ADSP21364 with MATLAB ? I have a program running on the board which collects audio samples and put them in a frame and then calculates the power spectrum based on the contents of the frame. I would like to monitor this power spectrum in MATLAB while the program is running. Is that possible?

Hi All, Here a rather specific question: I'm programming the ADSP TS-201 and trying to start a link port DMA transfer. I set up the link control regs and necessary quad word, as specified(pointer,count,length, etc....). After writing the quad word to the TCB, the DMA should start and the data gets sent on its way. Here's my problem - when I stop the DSP and take a look at the TCB, I see that th...

Dear all, I am trying to interface 2 D/A converters to the SPORT serial port of a ADSP-21065L on an EZ-Kit Lite board. The converters are located on a daughterboard approximately 6 inches away from the EMAFE connector where the serial port signals are tapped. The converters do not receive the serial signals directly. Instead, the serial signals are buffered by a SN74AHC245 fast TTL buffer ...

Hello, I have a problem host booting my SHARC 21161 Multiprocessor system. I get System hangs due to a HBG# hang each time I download the loader file generated with the Visual DSP environment. The same code just runs fine out of an EEPROM (I ensure to use a different bootloader for those two tasks). The ADSP 21161 Hardware Reference states that you can get those hangs writing to a non exis...

We are using ADSP-21065L SHARC DSPs and would like to tie up to 24 of them together using the SPORT in Multichannel mode.
