Hi there, I'm having problem with the size of my binary code. My program uses cosine, arc tangent and square root. My kit only has a memory of 8k. I'm not including the math.h file. Instead, I coded the functions in the program itself. When I compile using model-large the program compiles but the size is bigger than 8k. When I try to compile with model-small appears an error message. I appreciate any help. Nei
Sorry, The error message I get is removing robo20053.rel ?ASxxxx-Error-<a> in line 2572 of robo20053.asm <a> machine specific addressing or addressing mode error When I compile with model-large a binary that had 6K turns to have 9K. I'm using the command line that came with the compiler: "$NAME $EXT --vc --use-stdout --model-small --stack-loc 0xD0" so I dont't know what optimization set it's using. My kit has a RAM size of 256 bytes and the compiler shows me this report when I use model-large: Direct Internal RAM: Name Start End Size Max ---------------- -------- -------- -------- -------- REG_BANK_0 0x00 0x07 8 8 REG_BANK_1 0x08 0 8 REG_BANK_2 0x10 0 8 REG_BANK_3 0x18 0 8 BSEG_BYTES 0x20 0 16 DATA 0x08 0x1a 19 128 ---------------- -------- -------- -------- -------- TOTAL: 0x00 0x1a 27 128 Stack starts at: 0xd0 (sp set to 0xcf) with 48 bytes available Other memory: Name Start End Size Max ---------------- -------- -------- -------- -------- INDIRECT RAM 0x80 0 128 EXTERNAL RAM 0x0000 0x0104 261 65536 ROM/EPROM/FLASH 0x0000 0x264c 9805 65536 Is that correct?
"$NAME $EXT --vc --use-stdout --model-small --stack-loc 0xD0" That's not a Keil C51 command line! What compiler are you using? Note that this forum is specifically for Keil products: http://www.keil.com/forum/
Sorry, I'm using SDCC, I couldn't get Keil. Thanks.
