刷路由固件手里没编程器就网上到处找后来发现了开源编程器
http://www.flashrom.org 然后用stm8实现了个适配器 这些是几个月前的事了 烧写了flash后就丢那了 今天又要烧芯片整理了一下修正了一个bug 顺手发上来吧 因为很简单所以也没有电路图, 一片STM8S103F3最小开发板即可
- MCU频率 16MHz
- SPI 波特率 fMASTER/2 = 8Mhz
- UART 波特率 fMASTER/16 = 1Mhz
- MCU 外部链接
- STM8S103F -> xx
- PD5 (UART1_TX 2) -> PL-2303HX RX
- PD6 (UART1_RX 3) -> PL-2303HX TX
- PC4 (14) -> LED RED
- PC3 (13) -> LED GREEN
- PD3 (20) -> SPI FLASH SPI_CS (1)
- PC7 (SPI_MISO 17) -> SPI FLASH SPI_MISO (2)
- VCC -> SPI FLASH wp# (3)
- GND -> SPI FLASH GND (4)
- PC6 (SPI_MOSI 16) -> SPI FLASH SPI_MOSI (5)
- PC5 (SPI_SCK 15) -> SPI FLASH SPI_CLK (6)
- VCC -> SPI FLASH HOLD (7)
- VCC -> SPI FLASH VCC (8)

读还可以写就比较悲催了, 临时对付一下还不错.
