Hi, I hope this is the right place to post this..
I'm trying to program an attiny45 using an arduino as a programmer (see megai-sp http://code.google.com/p/mega-isp/). I am using the latest winavr package and can program the attiny sucessfully if I use a small hex file and specify -t13 -F to make it look like a tiny13. If I use exactly the same parameters with -t45, it fails to verify. Reading | ################################################## avrdude: verifying ... avrdude: verification error, first mismatch at byte 0x0000 0x0e != 0x00 avrdude: verification error; content mismatch I suspect therefore that there's a problem with avrdude, specificly avrdude.conf. I attach the attiny45 section. #------------------------------------------------------------ # ATtiny45 #------------------------------------------------------------ part id = "t45"; desc = "ATtiny45"; has_debugwire = yes; flash_instr = 0xB4, 0x02, 0x12; eeprom_instr = 0xBB, 0xFF, 0xBB, 0xEE, 0xBB, 0xCC, 0xB2, 0x0D, 0xBC, 0x02, 0xB4, 0x02, 0xBA, 0x0D, 0xBB, 0xBC, 0x99, 0xE1, 0xBB, 0xAC; stk500_devcode = 0x14; ## avr910_devcode = ?; ## Try the AT90S2313 devcode: ## avr910_devcode = 0x20; avr910_devcode = 0x01; signature = 0x1e 0x92 0x06; reset = io; chip_erase_delay = 4500; pagel = 0; bs2 = 0; pgm_enable = "1 0 1 0 1 1 0 0 0 1 0 1 0 0 1 1", "x x x x x x x x x x x x x x x x"; chip_erase = "1 0 1 0 1 1 0 0 1 0 0 x x x x x", "x x x x x x x x x x x x x x x x"; timeout = 200; stabdelay = 100; cmdexedelay = 25; synchloops = 32; bytedelay = 0; pollindex = 3; pollvalue = 0x53; predelay = 1; postdelay = 1; pollmethod = 1; hvsp_controlstack = 0x4C, 0x0C, 0x1C, 0x2C, 0x3C, 0x64, 0x74, 0x66, 0x68, 0x78, 0x68, 0x68, 0x7A, 0x6A, 0x68, 0x78, 0x78, 0x7D, 0x6D, 0x0C, 0x80, 0x40, 0x20, 0x10, 0x11, 0x08, 0x04, 0x02, 0x03, 0x08, 0x04, 0x00; hventerstabdelay = 100; progmodedelay = 0; hvspcmdexedelay = 0; synchcycles = 6; latchcycles = 1; togglevtg = 1; poweroffdelay = 25; resetdelayms = 1; resetdelayus = 0; hvleavestabdelay = 100; resetdelay = 25; chiperasepolltimeout = 40; chiperasetime = 0; programfusepolltimeout = 25; programlockpolltimeout = 25; memory "eeprom" size = 256; page_size = 4; min_write_delay = 4000; max_write_delay = 4500; readback_p1 = 0xff; readback_p2 = 0xff; read = "1 0 1 0 0 0 0 0 0 0 0 x x x x x", "a7 a6 a5 a4 a3 a2 a1 a0 o o o o o o o o"; write = "1 1 0 0 0 0 0 0 0 0 0 x x x x x", "a7 a6 a5 a4 a3 a2 a1 a0 i i i i i i i i"; loadpage_lo = " 1 1 0 0 0 0 0 1", " 0 0 0 0 0 0 0 0", " 0 0 0 0 0 0 a1 a0", " i i i i i i i i"; writepage = " 1 1 0 0 0 0 1 0", " 0 0 x x x x x x", " a7 a6 a5 a4 a3 a2 0 0", " x x x x x x x x"; mode = 0x41; delay = 6; blocksize = 4; readsize = 256; ; memory "flash" paged = yes; size = 4096; page_size = 64; num_pages = 64; min_write_delay = 4500; max_write_delay = 4500; readback_p1 = 0xff; readback_p2 = 0xff; read_lo = " 0 0 1 0 0 0 0 0", " 0 0 0 0 0 a10 a9 a8", " a7 a6 a5 a4 a3 a2 a1 a0", " o o o o o o o o"; read_hi = " 0 0 1 0 1 0 0 0", " 0 0 0 0 0 a10 a9 a8", " a7 a6 a5 a4 a3 a2 a1 a0", " o o o o o o o o"; loadpage_lo = " 0 1 0 0 0 0 0 0", " 0 0 0 x x x x x", " x x x a4 a3 a2 a1 a0", " i i i i i i i i"; loadpage_hi = " 0 1 0 0 1 0 0 0", " 0 0 0 x x x x x", " x x x a4 a3 a2 a1 a0", " i i i i i i i i"; writepage = " 0 1 0 0 1 1 0 0", " 0 0 0 0 0 a10 a9 a8", " a7 a6 a5 x x x x x", " x x x x x x x x"; mode = 0x41; delay = 6; blocksize = 32; readsize = 256; ; # ATtiny45 has Signature Bytes: 0x1E 0x92 0x08.

Any ideas anybody?
