# 升级说明 # | ||
# CMSIS-DAP 升级说明 # | ||
CMSIS-DAP 使用stm32f103c8t6,由于flash只有64KB,升级需要使用另外一个仿真器对其进行升级, | ||
如stlink + st utility,jlink + jflash,或者cmsis-dap + openocd/pyocd。 | ||

# DAPLink 升级说明 # | ||
DAPLink使用 stm32f103cbt6,flash大小为128KB,DAPLink自带一个带U盘的bootloader,可以方便的 | ||
进行拖拽升级,升级步骤如下: | ||
1. 使用杜邦线将nRST和GND短接。 | ||
2. 将DAP插入到PC中,预期应该会出现一个名为MAINTAIN的U盘。 | ||
3. 此时可以将nRST和GND断开。 | ||
4. 将新的固件拖动到MAINTAIN U盘中,即可自动完成固件升级。 | ||

||
PS: | ||
all-in-one-image目录下为完整的128KB镜像,若需要烧录此目录下的镜像,则和CMSIS-DAP一样, | ||
需要另一个仿真器对其进行升级,其他目录下则可以通过拖拽方式进行升级。 | ||
