Hi all I have two batch of boards with TMS320CV5509A dsps. The first batch is programming fine using JTAG and I can run the program just using JTAG (without external memory). In the second batch revision, for some reason i cannot get the Jtag to get working. It comes up with POWER Failure error as if it is having problem detecting power on the PCB. I have checked the PD line and it is g...

Hi Do you know in C55x dsps the following: I use fread to read 16-bit samples from a file but even I use "2" as the size parameter for fread but it reads 8-bit samples for each execution of "fread" function. So How can I read a 16-bit samples by fread? Also is it possible to set the arrange of memory in a manner that we could access it in byte or word(16-bit) samples. Regards

TI tech support must be confused, or you must have confused them. If that were true, then what are the XARn registers for? C55x is an improvement over C54x. > d

Hi all I have written a C source code for C55x simulator in which I have used the "fopen" function for reading the input samples from a file. But when my program counter reaches to fopen execution the following error is displayed several times and the program exits: Invalid CIO command (0). I deleted the "fopen" and "fprint" and other file related functions and use a constant array as ...

Hi, I am having problem in programming the flash chip (chip-id: S29AL004D) which is interfaced with TMS320C5510 DSP. I am trying to program the Flash using sdFlash Utility provided by Spectrum Digital through SD510USB emulator. I have updated algorithm files for the Flash Erase/Program/Verify. Flash Erase operation is working fine for me. When I try to do Flash program operation the following ...

Arvid- That's great to hear you got it working reliably. Intermittent problems like that are always rewarding to solve. One additional comment: since you fixed it using boot code (generated by hex55.exe), you might want to comment your main.c or other source code in some way to show the inits (below). Otherwise people looking at your code in the future may not realize this initializat...
