Hello pals I am using Tms320C6211 DSP & CCS ver 2. I am configuring the McBsp port using the MCBSP_configArgs . I find this strange observation. The SPCR ,RCR,XCR get configured according to my configuration except for the PCR. The PCR remains 0 throughout . But when i make an explicit write to the PCR register then the register changes. I checked the csl_mcbsphal.h file , the address for the PCR is correctley defined as 0x018c0024. Can any one suggest as what might be the problem. waiting eagerly for ur kind reply Bye R.J.Nayaka | |||

I am using ccs2.1 and csl. The address of PCR in csl_mcbsphal.h is right. But the address of XCR is wrong with 0x01840010 (it should be 0x18c0010), i.e.: #define _MCBSP_XCR0_ADDR 0x018 4?(c) 0010u Perhaps you have some other wrong code to mislead you to PCR.

I have a computurized imaging system based on a DSP board. I have two digital data LSYNC and FSYNC. The DSP captures a line of data at every LSYNC and FSYNc gives the information that the frame is started. I used openGL graphics program to display the data. I encountered such a problem that RANDOMLY some lines are shifting to left at some frames. Those lines seems to be compressed and other memories in shifting region are empty. In DSP part I used double buffer. At every FSYNc I transferred the block of data to another buffer. Do you think that the DSP is overwriting the data to previous one? I will be glad, if anyone encountered such a problem can help me. Thanks beforehand Kind regards, Mustafa kan RA METU |
