Hey guys, it's me again! Trying to get rid of the need of Keil I am trying to be able to debug a program that was compiled under the SDCC. The program runs on a eval-board which communicates with a server. I can communicate with this server by bridgeing some .dll files which then allows me to do stuff like this: // a java plugin server.getDevice.getPc(); server.getDevice().getAllRegisters(); and so on.. But all this would only make sense if I was able to "highlight" that line on wich the PC at the moment is. Keil generates a table like: C:C006H LINE# 60 C:C009H LINE# 62 C:C00FH LINE# 63 C:C014H LINE# 64 so if the PC == 0xC006 line 60 in the corresponding .c file would be highlichted. Can anyone provide me some guideline how I could manage this under Eclipse? - I got a plugin - I can receive all ?C information - I (technically) can debug in Eclipse already (but without useful visualisation) but - I can not associate the PCs address with a specific line of a .c or .asm file to highlight it in Eclipse Is there already an easy way how one could do this? If not, where can I get a description about how I can filter these information from the files that will be generated using the "--debug" option? Okay, I know this is not a small request from me but I'd be glad about anything that could help me since getting so far really took me a lot. Thank you very much and best regards, Stefan
There used to be a link on the SDCC web page that described the .cdb file format that has debugging information, including the line/address relationships. I'm not sure what happened to i, but I'll tell you the part you need to know.
The .cdb file is a plain text file with one debugging record per line. The lines that begin "L:C" are the records with the address of a particular "L"ine of "C" source. This is followed by the source filename and line number, both separated by the "$" symbol. Then there are two other fields that aren't particularly important, also separated by a "$" symbol. At the very end is a ":" symbol and the hexadecimal address associated with that line (although there is no prefix explicitly denoting the use of hexadecimal).
So for example, the line: L:C$sample.c$32$1$16:51indicates that the code associated with line 32 of sample.c begins at address 0x51 in memory.
Although I have no idea how to integrate this with Eclipse, it should be fairly simple to translate the line/address information in the .cdb file to the format that Keil generated using a convenient scripting language of your choice.
