今天終于琢磨出來(lái)怎么在linux下燒錄AT89s52.
下面是我的方法...當(dāng)然可能有更好的方法.
這里以Ubuntu為例子,先安裝avrdude.
用下面的命令一次裝全吧:

sudo apt-get install gcc-avr binutils-avr avrdude avr-libc

然后編輯avrdude.conf:

sudo gedit /etc/avrdude.conf

在最后面加入AT89s52的相關(guān)信息(這是Joy Shukla寫(xiě)的)

#------------------------------------------------------------
# Below chips by added by me .. Joy Shukla(joy_shukla@yahoo.in)
# these chips can be programmed with my usbasp programmer(changed atmega8 program)
# after adding avrdude support in this file ..
#------------------------------------------------------------

#------------------------------------------------------------
# AT89S52
#------------------------------------------------------------
part
id = "8052";
desc = "AT89S52";
signature = 0x1E 0x52 0x06;
chip_erase_delay = 20000;
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 = 0;

memory "flash"
size = 8192;
paged = no;
min_write_delay = 4000;
max_write_delay = 9000;
readback_p1 = 0xff;
readback_p2 = 0xff;
read = " 0 0 1 0 0 0 0 0",
" x x x a12 a11 a10 a9 a8",
" a7 a6 a5 a4 a3 a2 a1 a0",
" o o o o o o o o";

write = " 0 1 0 0 0 0 0 0",
" x x x a12 a11 a10 a9 a8",
" a7 a6 a5 a4 a3 a2 a1 a0",
" i i i i i i i i";
mode = 0x21;
delay = 12;
;

memory "signature"
size = 3;
read = "0 0 1 0 1 0 0 0 x x x 0 0 0 a1 a0",
"0 0 0 0 0 0 0 0 o o o o o o o o";
;
;
#------------------------------------------------------------
然后保存
現(xiàn)在就可以燒錄AT89S52的單片機(jī)了,
例如我想燒錄放在桌面上的編譯好的跑馬燈程序,
用命令

sudo avrdude -p 8052 -c usbasp -e -U flash:w:/home/vowstar/桌面/跑馬燈.hex

即可
效果如圖:

開(kāi)發(fā)板上的效果:

注意事項(xiàng)：

如果提示器件沒(méi)有響應(yīng)，signature = 0x000000原因是：usbasp的固件不能用原裝的 （http://www.fischl.de/usbasp/）
要用來(lái)自這里的http://www.8051projects.info/blogs/usb-8051-avr-programmer.html

2. 提示：~/Desktop $ sudo avrdude -p 8052 -c usbasp -e

avrdude: Cant find programmer id "usbasp"

Valid programmers are:

上面這種情況接 usbasp編程器(并口的)到電腦上,然后在終端下執(zhí)行命令lsusb,提示：
~/Desktop $ lsusb
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

這樣看來(lái),編程器沒(méi)問(wèn)題可以被識(shí)別.
檢查一下/etc/avrdude.conf中是不是上文所述配置,然后檢查編程器的跳線(xiàn)設(shè)置,跳線(xiàn)帽錯(cuò)沒(méi),再檢查一下單片機(jī)是不是AT89S52,
最后確認(rèn)單片機(jī)外圍不能接其他影響IO傳輸?shù)钠骷?比如DS18B20,ULN2003等,斷開(kāi)它們?nèi)缓髧L試下載.
下載程序時(shí)要用root權(quán)限
