Tags:OpenOCD DAP-LINK 调试 ESP32 经历

目的

手里有调试STM32的DAP-LINK,想试试通过JTAG调试ESP32

OpenOCD支持CMSIS-DAP

DAP-LINK支持的芯片,我手上这款描述如下,应该JTAG协议的都支持

平台

windows10 + ESP-IDF

ESP-WROOM-32E模组 + 烧录底座

DAP-LINK

乐鑫OpenOCD

使用乐鑫官方的OpenOCD,结果无法识别CMSIS-DAP设备

官方OpenOCD

官方接口支持CMSIS-DAP,但是芯片并不支持ESP32

有cmsis-dap.cfg

没有esp32的cfg

使用官方OpenOCD,配置文件使用乐鑫的,CMSIS-DAP可以正常识别,但确实不支持ESP32芯片

结论

  1. 乐鑫OpenOCD不支持CMSIS-DAP

  2. 官方OpenOCD支持CMSIS-DAP,但是不支持乐鑫的芯片

  3. 寄,还是下单了ESPLink
