Hi, I am using EVM 6201, with CCS 2.0 Problem I am facing is related to printf. My code uses printf and FILE I/O. Mostly it is working perfectly, but then some times the printf in the begining do not print result properly, looks like it's having problem in using buffers, as the successive printf calls are affected by previous calls ( data repeatedly printed some times, and some times it prints garbage data). I was suggested to use DSP/BIOS, and hence LGO_printf. I used that, and it works fine. But then in some calls, it prints odd error some what like "Error 0x80001233(0x5)." where 0x80001233 is address of string to print, with valid string message data. I want to use printf in separate code as well. Please please suggest me what can be the problem with these printf's. regards, Vishal. |

Hi there, Have you manually set your .sysmem size? default is only 0x400. You might want to try to make it bigger. Build options, Linker tab, heap size. regards, Jonathan -----Original Message----- From: goelhss [mailto:] Sent: Mon 3/17/2003 11:42 PM To: Cc: Subject: [c6x] LOG_printf and printf Hi, I am using EVM 6201, with CCS 2.0 Problem I am facing is related to printf.

Hi Goel We too faced the problem with printf function. its behavior is very unpredictable. i suggest u to use puts() function which seems to be better than the printf() function. this prints only strings. But we never faced any problem with the LOG_printf() function. And one more thing Log_printf function only displays in the messagelog windows. one thing u can look into the where memory is allocated for the LOG_printf() Objects in the memory Manager of Gconf window. Just see is there enough memory is avialable for the LOG_printf objects. u can increase the size little bit more and try it. Hope this helps u. There are many routines in the RTS.lib which are not reliable. Ex atoi()... etc regards Amaresh Patil --- goelhss <> wrote: > Hi, > > I am using EVM 6201, with CCS 2.0 > Problem I am facing is related to printf. > My code uses printf and FILE I/O. > Mostly it is working perfectly, but then some times > the printf in the begining do not print result > properly, > looks like it's having problem in using buffers, as > the successive printf calls are affected by previous > > calls ( data repeatedly printed some times, and some > times > it prints garbage data). > > I was suggested to use DSP/BIOS, and hence > LGO_printf. > I used that, and it works fine.
