Hi, My toolchain information Host : redhat linux 7.1 in a i386 PC Tool chains built as per Brad LaRonde's writeup. (Building a Modern MIPS Cross-Toolchain for Linux) gcc: version 3.0.3 binutils : version 2.11.92.0.7 20011016 glibc: version 2.2.3 with linux threads patch and mips-base-addr patch from Brad. I was able to build kernel 2.4.3, I got from oss.sgi.com and it works fine (thanks to everyone). So I assumed my toolchain is working fine. Next I modified the yamon startup code (just used reset.S, gt64120.S, link.xn and did some cleaning to get it compiled). When I tried to run srecconv.pl util, I got error message "Out of memory!" (I wanto convert it into flash format to download. The strange thing is, I have an Algorithmics toolchain version egcs-2.90.23 980102, GNU ld 2.9.1/sde-4.0.3, and the srec I got from it doesnt havethis problem) I tried to trace down and found that the srec generated has load address 0x80001000 for data and 0xbfc00000 for the startup code (this is because the link.xn is defined this way). So when an associative array is used in perl script srecconv.pl, it runs out of memory. I dont know perl and I am stuck here. Can somebody point me how to proceed? thanks a lot. (i really want to have the data loaded at 0x80001000 but it should be initially in flash). So I changed the data load address to 0xbfc01000 and now the srecconv works fine and I got a .fl image. But my "jal gt64120_init" is assembled to use _gp and I dont think I set the _gp properly ( I am still in the process of reading Dominics book:). so the code is not at all entering in to the gt64120_init function. but when I change it to "j gt64120_init" it works fine. (Cant I use "jal" here?) Any help would be appreciated and sorry for this long mail, Thanks, Muthu
