I didn't get any error messages... I found the __initrleblock in crt0_rle.s. But right now that's not the problem.
I compiled with: sdcc -c -I../../Firmware/include -mz80 --xram-loc 0x8000 banksw.c sdcc -I../../Firmware/include -mz80 --xram-loc 0x8000 main.c banksw.o Oh yeah, the current problem is when my program starts running. heres the intel hex object file: (i'll explain after the file ) :03000000C3000139 :02000800ED4DBC :02001000ED4DB4 :02001800ED4DAC :02002000ED4DA4 :02002800ED4D9C :02003000ED4D94 :02003800ED4D8C :0C01000031FFFFCDE402CD3702C3040242 :0E0200003E02CFC93E00CF7618FDE1C5D54EB7 :0E020E002346235E23CB7BCA23027E230203FA :0E021C001CC21A02C31102AFB3CA33027E2302 :0D022A0002031DC22802C31102D1C1E5C9A3 :0102E400C950 :0E023700DDE5DD210000DD3921FAFF39F92176 :0D0245000300394D44C5FDE1C5FDE5E1CDE7 :0E0252000A020355550300C1210000395D5416 :0E026000D5FDE1C5D5FDE5E1CD0A0203AAAA50 :0E026E000100D1C1C5D5C5CD8C02F1D1C1C5ED :0E027C00D5D5CD8C02F1D1C1C37202DDF9DD02 :02028A00E1C9C8 :0E028C00DDE5DD210000DD39DD4E04DD460537 :0E029A000AD3045950131AD30503030AD306DE :0E02A800DDE1C9DDE5DD210000DD39DD6E049C :0E02B600DD6605E5CD8C02F1FD210120FD364F :0E02C4000000DDE1C9DDE5DD210000DD39DDF2 :0E02D2006E04DD6605E5CD8C02F12100204EA4 :0402E00069DDE1C92A :00000001FF We can see the usual empty ISR from line 2 to 8 and at line one theres the jp to init at address 0100. At address 0100 the sp gets initialized with 0xFFFF (witch is perfect) and then calls a routine at 02E4 at address 02E4 there's a RET (69h) so the code jumps back at address 0206. But when it does, the CPU actually executes a RET at address 02E4 and directly after that it executes a RESET, witch sets the PC back at 0000 ... instead of calling routine at address 0237 witch is my main()...
