STM32: 做一个与ST-LINK/V2-1调试器兼容的BOOTLOADER(二)

原文在此:

STM32: 做一个与ST-LINK/V2-1调试器兼容的bootloader

完整代码如下:

https://github.com/brobwind/chibios_bro_dbg_link_v2_1

编译使用 gcc-arm-none-eabi-4_8-2013q4

将该编译工具链加入path之后,执行make命令编译:

$ make
Compiling crt0_v7m.s
Compiling chcoreasm_v7m.s
 ...
Linking build/ch.elf
Creating build/ch.hex
Creating build/ch.bin
Creating build/ch.dmp

   text	   data	    bss	    dec	    hex	filename
   9272	    476	  20384	  30132	   75b4	build/ch.elf
Creating build/ch.list

Done
bogon:chibios_bro_dbg_link_v2_1 hello$ 

修改标识:

$ echo -e -n '\x15\x3c\xa5\x47' | dd of=build/ch.bin bs=1 seek=0x100  conv=notrunc

通过openocd写入固件的脚本如下:

#! /bin/bash
set -e -x

FW=build/ch.bin
ADDRESS=0x08000000

OCD=/usr/local/bin/openocd
${OCD} -f interface/stlink-v2-1.cfg -f target/stm32f1x.cfg -c init -c "reset halt" -c "stm32f1x unlock 0" -c "reset halt" -c "exit"
${OCD} -f interface/stlink-v2-1.cfg -f target/stm32f1x.cfg -c init -c "reset halt" \
        -c "flash erase_sector 0 0 127" \
        -c "flash write_image erase ${FW} ${ADDRESS} bin" \
        -c "verify_image ${FW} ${ADDRESS} bin" -c "reset run" -c shutdown

目前存在的问题主要是:

如果再通过Stlink Utility进行升级的操作,升级时无法进入bootloader模式。

希望有一天能够解决这个问题。
