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

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...
