Dear All, I am very new to this group. I tried to load my .serc file into my Db1500 SDB. The steps that I followed are, 1) I wrote a filein C(Linux). 2) I generated an object file using gcc. 3) By using objcopy I converted my obj file into srec file. 4) Then I tried to download my srec file into Db1500 SDB in Yamon using tftp. then I got error as, Error: No match in TLB for mapped address : Address = 0x00000000 Why I am getting this error ?. Is any error there in my procedure..? Thanks in Advance. Regards, Srinivas JT
