I use CodeWarrior IDE 4.1 (buil 0622) for Motorola 56800 on Windows 95. I have also upgraded with patch 4.0.2 came with SDK 2.4 CDROM. When I link the simple code of main.c this error occur: " Link Error : Symbol Feanpos_table is too far away for a R_56800_WORD relocation from section .text in file main.c. Link failed. " Simple code: ======================= void* Pn; short Temp; unsigned short Temp2; unsigned short ref; typedef struct /* hook callback info */ { unsigned short type; void * address; const void * low_limit; const void * high_limit; } table_row; static const table_row eanpos_table [ 2 ] = { /* type address uplimit lowlimit */ { 0x0023, &Temp, &Pn, &Pn }, /* 2 */ { 0x1710, &Temp, &Pn, &Pn } /* 86 */ }; void main (void) { Temp2 = eanpos_table[ref - 3000].type; return; /* C statements */ } ================ Does anyone have the same problem ? I also attach a simple project if someone want test it !!!

Hi Giuliano, I checked with our technical support team and they told me that they had a report on this and hand responded in private e-mail. If you have any problems with supports reply, feel free to write directly to me and I'll look into it and see what I can do. I trust this won't be necessary.

Hi All, I'm very new to DSPs, and find I am in need of some more help. I have found the "Digital Signal Processing Applications With Motorola's Dsp56002 Processor" book, but wonder if there is a more recent publication. Or is the above book going to be still very relevant to the DSP568xx series. I have experience with Motorola micros (HC12 etc.). So it's the DSP bit I still don't get. Any suggestions most welcome. Thanks. Peter L. |

Peter, The book that you have is a good introduction into DSP in general (as the DSP56002 was a good DSP for Motorola for many years but has now kind of hit the end of its lifetime), but if you will be specifically using the DSP56800, I recommend that you try taking a look at the following materials and use the following resources: A) DSP5680X User's Manual (DSP56801-7UM/D)- Detailed User's Manual for the DSP5680X series of processors (801,803,805,807). B) DSP56800 Family Manual (DSP56800FM/D) - Contains the instruction set for the DSP568xx and talks about the DSP568xx family. This documentation will help you with the hardware and detailed chip details that you need to know.......however the other side of the story is the software which is also very important for the DSP568xx series of processors. For this information, I recommend that you try CodeWarriorU.com which has a course that specifically targets the DSP568xx family of processors and deals with how to work with the development software (CodeWarrior + Embedded SDK) that is necessary for success using this part.
