need help on the 5402 dsk regarding FIR implementation - kusuma - May 24 1:35:00 2002

Hi,
While implementing the FIR filter using DSK 5402, CCS 1.22 we are facing the following problems. 1. While loading the .out file on to the processor, we are getting the error message "Data verification failure at 0xxxx(some random address)". 2. After successful loading the .out file after resetting the board many times, in disassembly mode the program looks fine. But if we put break point in some location, we are seeing some unknown insrtuctions which are not in the .asm file. 3. After executing the program and halting it the control is going to some unknown location. The asm code is attached for reference. Please help us regarding this. The files are 1. mainFIR22.asm 2. ad50_init.asm 3. vectors.asm 4. main.inc 5. init54x.inc If anyone can identify the problem please let me know. thanks& regards, kusuma | |||

Subject: Subject: need help on the 5402 dsk regarding FIR implementation ** Proprietary ** Hi 1) The ccs have this data verification failure very often for that u need to load the gel file dsk5402init and then u try loading the program here the chances of failure will be less.The reason is the gel file will put all ur cpu registers to its default value. (2) & (3) if u can send me ur files i will be able to help u more normally this happens if the interrupt mapping is not done correctly eg. in vectors.asm the isr starting address maybe mapped at 7ff80 but ur reset vector will always start at ff80.If u want to relocate then u have to change the IPTR register value, because of this mismatch it may branch to some unkown locations. There is no attachment. regards vinodh rathna Message: 3 Date: Fri, 24 May 2002 09:35:51 +0800 From: "kusuma" <> Subject: need help on the 5402 dsk regarding FIR implementation Hi, While implementing the FIR filter using DSK 5402, CCS 1.22 we are facing the following problems. 1.
